The AlfaPure range comprises purpose-built centrifugal separator systems for removing oil, grease and solid particles from water and oil based liquids, such as coolants, lubricants and wash liquids.

Efficient cleaning of service fluids pays off
Utilizing centrifugal separation, the AlfaPure range is a series of extremely efficient systems for cleaning industrial service fluids, such as coolants, wash liquids and mineral oils. Removing oil, grease or particles from these fluids makes them last much longer and reduces machine tool wear, leading, in turn, to increased uptime in your plant. It also results in cleaner, healthier working conditions in the workplace.

Longer service life for fluids
Continuous cleaning extends the life of wash liquids by up to six times, while coolants can be made to last as long as ten years, with dramatic savings in replacement costs. The costs of disposing of contaminated liquids and filters are also greatly reduced.

Extremely efficient cleaning

Centrifugal separation is the most efficient method available of cleaning service fluids. It removes water, abrasive metal fines and other particles as small as 2 μm, therefore machine tools give much longer service before wearing out. This means considerably lower tool replacement costs. Reduced tool wear also results in more precise machining and fewer rejects.

Complete system design
AlfaPure systems are built around centrifugal separators. Each system is a complete plug-and-play module, including separator, feed pump, sludge pump and an easy-to-operate control panel, a PLC control system that handles all valve and pump settings automatically. Normally installed in a bypass system, the unit operates continuously without interrupting machinery operations. This also means no plant redesign is needed

Optimized to your needs
Several AlfaPure systems are available to choose from, enabling to find the best available solution for different applications. Check our product range shown below and look at the technical details in the documentation section.

Alfa Laval FALCON treatment systems use centrifugal separation to remove any solids and water that might contaminate the fuel and lube oils used in a wide range of engine equipment.

The Alfa Laval FALCON system is designed to help protect the engine equipment used in the oil and gas industry by keeping fuel and lube oils clean. This ensures reliable performance, cuts down on service, maintenance and downtime, and extends the service life of key installations. These benefits make FALCON units popular for use on offshore oil and gas drilling rigs and production platforms, where reliable engine equipment can be mission critical and downtime particularly costly.
The FALCON separator units feature a compact, modular design centred around a disc stack centrifuge, one of Alfa Laval's main separator technologies. The basic equipment comprises the centrifuge module, an electric motor and built-in paring disc pumps for clean oil and dirty water. A range of other ancillary equipment is available to provide a complete installation for removing any solids and water that might contaminate the fuel and lube oils.
FALCON systems provide automatic, unattended operation, with the important advantage of being self-cleaning. No pre-filtration is needed, and with no filter cartridges disposal of any sludge removed from the fuel oil or lubricant can be done in an environmentally responsible manner.
Installing a FALCON unit between the bunker tank and the day tank helps protect diesel engines by removing any undesirable water and sludge particles from the fuel. The FALCON range also includes modular, self-cleaning units designed to deal with heavier types of fuel and crude oils. These installations include the requisite pre-heaters, starter units and control panels, with other equipment available as options.
Alfa Laval FALCON units are also extremely effective at ensuring that the lubricating oil for engines is clean. They remove virtually all the contaminants likely to be encountered in lube oil, including condensate, sludge and particles that stem from combustion or wear on moving parts, and any effects of cooling system leaks or salt water entering the crankcase.

PureVent is a radical new approach to cleaning the gas vented from engine crankcases by using centrifugal separation technology to remove oil mist and other particles, and help protect the environment.

An estimated 3500 m3 of lube oil ends in the world's oceans every year by allowing crankcase gas containing oil mist from marine diesel engines to pass into the atmosphere un-cleaned. This oil mist can drift long distances in aerosol form before the droplets finally settle on the sea – or on land, with the pollution this entails.
Although there are stringent regulations regarding oil discharges in bilge water, there are – as yet – no limitations on oil discharges into the sea via crankcase ventilation. Exhaust emissions from such engines are normally the prime concern, but crankcase gas still represents important environmental and health concerns. Crankcase gas is much less diluted and can cause high oil concentrations in limited areas. The oil mist can also soil a ship's engine spaces, decks and areas near the ventilation outlet. This is highly undesirable on board cruise ships, for example.
PureVent represents a radical new approach to the cleaning of crankcase gas in high-capacity installations. Developed specifically for use with marine diesel engines and power plant generators, PureVent technology employs high-speed centrifugal separation to separate oil mist and other particles from the crankcase gas produced by these engines. The separated oil can even be re-circulated for use as lubricant.
Cleaning efficiency is as high as 99.99% for a capacity of 40 m3/hour and 98.5% at 150 m3/hour. These performance values cannot be matched by any previous technology – traditional cyclones, air traps and filters have never been able to provide satisfactory results.

Alfie centrifugal separators remove the contaminating oil, grease and solid particles from coolants used in industry, helping prevent tool wear and avoid disposal problems.

Coolants are a major expense throughout metalworking industry, and replacing them once used is often messy and time-consuming. Disposing of used, contaminated coolants is also a continually escalating expense due to the need to comply with increasingly stringent environmental regulations.
Dirty coolants also result in substantial follow-on costs. Any tramp oil or solid particles present in a coolant can cause substantial wear on expensive tools and equipment, quality problems during subsequent processing and health problems for staff.
The Alfie range of compact high-speed centrifugal separators makes it easy to significantly reduce all such costs by keeping coolants clean, and do so in the most cost-effective way possible. Alfie units can be linked to a bypass flow, ensuring less downtime for service. In addition, fewer man-hours are required for maintaining service fluids. An Alfie separator plays a key role in ensuring longer tool service life and cleaner components, thus improving end-product quality.
The Alfie range currently consists of two different units. The Alfie 200 is designed for mounting on top of coolant tanks, and is fitted with a bellows that automatically adapts the inlet to the level of fluid in the tank.
The Alfie 500 is a compact, wheeled separator system that the operator can move from one tank to another. The PLC-based control system is easy to use, and special couplings make it easy to connect and disconnect the hoses quickly when moving the cleaning unit around.

The S and P Flex range of separator systems for fuel oil and lubricating oil combines the unique strengths of Alfa Laval's S separators and P separators with a modular concept for truly flexible supply.

The S and P Flex range combines essential protection with high flexibility, letting you design and construct your Alfa Laval separator system as you see fit. Incorporating the advanced efficiency of the newly updated S separator and the affordable simplicity of the P separator, it lets you choose the separation system that best meets your performance needs and available space.

• S separator
• P separator
• Low-wear mechanical platform
• Flexible supply

The S separator – newly enhanced

The S separator is the world’s best-selling and most efficient separator for fuel and lube oil. Using Alfa Laval’s unique Alcap technology, it automatically adjusts to the nature of your oil, giving you thorough protection and maximum economy from your fuel.

Today’s S separator contains enhancements that further increase its efficiency. Smart modifications in the disc stack, including an increase in separation area, allow up to 20% more flow with retained separation performance. This lets you process the same amount of oil with a smaller separator.

Additional features, including a more robust drive system, add to the S separator’s reliability and further reduce lifecycle cost.

The P separator

The P separator shares many features with the S separator, but it is designed for well-defined oils with fewer but vital process issues. Instead of the more refined Alcap technology, it has a manually set gravity disc or clarifier disc in the separator bowl.

The result is a separator with the same high performance, but one that is more suitable for lubricating and marine diesel oils, as it does not automatically compensate for density fluctuations.

A low-wear mechanical platform

S separators and P separators are built on a low-wear mechanical platform that features CentriShoot and CentriLock.

The CentriShoot discharge system, which greatly reduces sludge volumes, has a fixed discharge slide that flexes gently at the edges to expose the discharge ports.

The CentriLock bowl-locking system uses a lightweight, non-threaded snap ring that snaps in and lifts out with no more than an Allen key.

Both of these features prevent metal-to-metal wear. As a result, they minimize the risk of bowl replacement and significantly reduce lifecycle cost.

Flexible supply

The Flex range concept provides flexible options for the delivery of S separators and P separators:

• Flex system
  A separator with ancillaries as block components provides full say over the use of space in the engine room. This option allows local modularization or do-it-yourself assembly.
• Flex modules
  Customer-specified modules can be created using a wide variety of skids and machine blocks. Modular components can be delivered separately and assembled on site, which makes even larger systems easy to retrofit. Mixed modules are also possible for the simultaneous treatment of different mineral oils.

All deliveries feature the modular and easy-to-use EPC controller, which is based on standard supply and connects via Ethernet or bus communication to onboard automation systems.

This compact centrifugal separator cleans bilge water feed before it enters the existing bilge water treatment system onboard. This ensures compliance with international oil pollution prevention regulations for safe discharge overboard.

Cost-effective bilge water treatment
An economical and reliable alternative to installing a new bilge water treatment system, Alfa Laval PreBilge is cost-effective solution for upgrading ship bilge water treatment systems that do not currently meet, or have high operating costs in order to meet, international performance standards.
Using proven centrifugal separation technology, PreBilge oily water separator effectively cleans bilge water feed before it enters the existing bilge water treatment system, whether a gravitational coalescer or another type of system.
This ensures that cleaned bilge water discharged overboard by the existing bilge water system meets international regulations for an oil-in-water content of between 5 and15 ppm – even when the ship is subject to unfavourable roll, pitch and heave motions at sea.
Continuous oily bilge water pre-treatment
Installed as a pre-treatment loop, PreBilge runs continuously, providing the existing system with clean, problem-free feed. There is no need for the crew to monitor treatment, investigate oil-in-water alarms or change filters.
Compact, convenient installation
Easy to install, this compact oily water separator can be positioned anywhere in the engine room. Pipe connections can be drawn as needed so proximity to the vessel’s bilge water tank is not required.
Economical bilge water treatment
Since the discharge and oil monitoring are handled by the existing system, PreBilge does not require its own type approval or affect the vessel’s IOPP certificate. It ensures regulatory compliance and reduces operating costs while maximizing uptime with minimal effort and no change to the vessel’s paperwork.

The PX disc stack centrifuge range is designed exclusively for continuous degumming, neutralizing, dewaxing, and washing of various vegetable oils and animal fats, for small, medium and large capacity refining plants.

The PX range is based on a unique, semi-hermetic design concept. The hermetic, bottom-fed inlet ensures a gentle, non-destructive acceleration of the feedstock up to full bowl speed. The flow area for the feedstock has been increased to minimize inlet pressure drop. The outlets on the heavy and light phases are open, reducing the pressure drop across the separator. The feed-pressure requirement of the machine is therefore low.
The outlets are equipped with stationary paring devices for removal of the different phases. The paring disc on the light phase is fixed, while the paring tubes on the heavy phase are adjustable.
By adjusting a positioner on the heavy phase outlet, the operator can reduce or enlarge the paring diameter of the paring tubes. This patented innovation makes it possible to adjust the position of the separation interface during opera-tion, facilitating optimal separation.
With the working environment in mind, the PX range is designed to operate at low noise levels. This is achieved by means of a rubber-damped bearing assembly, jacketed frame and an outer bowl design engineered for low wind noise.

The bowl is fixed on top of the spindle, inside the space formed by the upper part of the frame, the solids collecting cover, and the frame hood. The hood carries the liquid discharge system.
All parts in contact with the process liquid are made of stainless steel. The bowl is a solids ejecting disc type, with an automatic hydraulic operating system for “shooting”.

Alfa Laval disc stack centrifuges for breweries are available in many different sizes and configurations, each specially designed for a specific kind of separation duty.

Alfa Laval has supplied high-quality separators to the brewing industry for decades. Alfa Laval brewery separators have proved crucial in enabling breweries around the world to achieve higher yields from greater efficiency, and in helping them meet changing demand patterns while maintaining profitability. Brewery separators from Alfa Laval ensure minimal levels of oxygen pick-up during passage through the separator, which is a major quality requirement for brewers. Hygiene issues are also a prime focus in all aspects of the design of these brewery separators.
The BREW series separators are all normally used within the following application steps in the brewing process:
pre-clarification
green beer separation
hot wort separation
beer recovery
With features and options such as Oxy stop, a hydrohermetic seal that ensures minimal oxygen pick-up in the clarified liquid, SmartEject self-triggering system, which provides intermittent discharge of solids that have a high dry matter content, a specially designed variable frequency drive (VFD) system provides benefits that include low starting current and a short time power supply, and much more, the brewer can customize the separator performance and capacity to a given application task to the optimum yield.

How it works

The LYNX drilling mud decanter centrifuge is built around a slender cylindrical bowl with a relatively large length/diameter ratio and a conical end. This bowl rotates at speeds of up to 3650 rpm (according to model), producing centrifugal force of anywhere from 300 to 3574 G. The other key components include a main drive motor, heavy-duty gearbox, back drive motor and control panel. The Alfa Laval direct drive gearbox ensures automatic control of the conveying speed.
The liquid drilling mud is fed into this long cylindrical bowl, where the centrifugal force presses it outwards to form a layer – known as the pond – around the wall. The thickness of this layer is determined by a series of discharge weirs at the end of the cylindrical section. The clarified liquid flows out over these weirs, with the aid of centrifugal force. Since the solids in the mud are heavier, they remain plastered against the bowl wall, and are continuously removed by the screw conveyor. They are then transported up to the conical section (known as the beach) where they exit via the discharge ports at the narrow end. Cleaned drilling mud exits at the opposite end.

A family of G - Alfa Laval's complete series of fuel ethanol decanters designed and built for ethanol producers. SG2 is the producers choice for ethanol production,

The world market for fuel ethanol is booming. Alfa Laval SG2 decanter centrfuges play an important role in enabling both new entrants and established players set up reliable, cost-effective processing facilities distinguished by low life cycle costs that help ensure solid profit margins.
The SG2 range of decanter centrfuges was designed and built with the specific requirements of ethanol production in mind. SG2 stands for "spent grain, generation 2".
With more than 400 units installed to date, the first generation of these units has been the preferred equipment in ethanol production for decades. The second generation consists of additional models and fine-tuned, improved performance for all existing ones.
SG2 units are the most cost-effective high-volume separation solutions currently available for processing dried distillers grains and solubles (DDGS). Thanks to their well-balanced, straightforward design, unique control systems and the use of robust, abrasion-resistant materials, they operate more reliably and more efficiently than any other comparable equipment – even at centrifugal forces as great as 3,500 G. They are used to process high-volume throughputs of stillage from all grain types in order to achieve a low level of suspended solids and high cake dryness, with reduced power consumption and lower life cycle costs.
The SG2-700 model is the current culmination of Alfa Laval's ongoing programme of fine-tuning the SG2 design in response to the evolution of customer requirements. The result is a decanter centrifuge that provides the driest cake, the clearest centrate and the lowest energy consumption on the market. Using less energy for evaporation and drying has a direct impact on bottom-line results. The SG2-700 model also features both a lower price point and smaller footprint than any previous models, paving the way to innovative configurations.

The Foodec range of decanter centrifuges brings a new level of separation performance to industries where delicate food and beverage products are processed and where exceptional hygiene standards are crucial.

Foodec decanter centrifuges combine unparalleled efficiency with exceptional hygiene, in a design that minimizes oxidation in delicate food and beverage products. They provide extremely efficient liquid extraction that leaves a particularly dry waste product. The Foodec design actually boosts solids handling capacity by as much as 25% compared with all other designs currently available – at no additional cost.
Foodec solutions are designed for separation duties in industries with a particular focus on hygiene standards and on avoiding the effects of oxygen pick-up. The unique Foodec design features an advanced sealing system that virtually eliminates any intake of air. This makes these units ideal for use in breweries and in the manufacture of a wide range of beverages and viscous foods, including wine, fruit juice, casein and lactose, coffee and tea, tomatoes and soy protein isolate.
The advanced drive system paves the way to much lower power consumption than any other current designs, and the innovative 2Touch control system reduces operating costs and gives even better control over the separation process. Together, this results in lower separation costs as well as boosting both the quality and value of the end product.

Alfa Laval Fuel Oil Cleaning Unit Solutions (FOCUS) are automated modular systems for purifying the liquid fuel oils used in gas turbine power plants.

The fuel cleaning process is designed to prevent the potentially harmful effects of contaminants often found in fuel oil, using a complete, pre-configured system with all sub-systems integrated effectively.
The liquid fuels used in gas-turbine power plants vary substantially in their physical properties and the amounts and types of contaminants they contain. The trace metals sodium and potassium are often present, as well as water and a range of solid particles. Such contaminants cause high-temperature corrosion, the formation of ash deposits and clogging of the fuel supply system, resulting in costly operating problems and downtime that affects revenue earning in the power plant.
However, with correct treatment prior to use, it is possible to employ a wide range of liquid fuels in any modern gas turbine power plant. By ensuring consistent compliance with specific fuel oil purification requirements, an Alfa Laval FOCUS (Fuel Oil Cleaning Unit Solutions) unit helps ensure extended turbine service life as well as a significant reduction in operating costs via less maintenance and downtime.
A FOCUS installation contains all the equipment necessary for cleaning fuel oil effectively and at low cost in a straightforward, compact and robust modular unit that provides automatic, unattended operation, if required. Using a FOCUS unit for fuel oil cleaning makes it possible to do away with pre-filtration and problems with disposing of contaminated filter cartridges, and ensure reliable operation and exceptional separation efficiency at all times.

A hermetic cell culture centrifuge, the Culturefuge is designed for gentle harvesting of shear-sensitive material in applications involving mammalian cell cultures and precipitated proteins.

Gentle product acceleration

The Culturefuge cell culture centrifuge is a hygienic clarification system for the gentle treatment of cell cultures and other shear-sensitive biological material. The unique hollow spindle enables gentle acceleration of the feed liquid to the rotational speed of the centrifuge, thereby minimizing cell lysis. This prevents the release of unwanted intracellular proteins or minimizes the destruction of fragile protein precipitates. Yields are thus enhanced and downstream operations optimized.

Scalable cell culture centrifuge
Ideal for cell culture fermentation and continuous cell harvesting under hermetic conditions, the Culturefuge delivers consistent product quality and can be accurately and reliably scaled up from use in laboratories and pilot plants to full-scale production.

Airtight cell culture centrifuge
The Culturefuge is a fully hermetic centrifuge, which effectively eliminates any air-liquid interface inside the separator bowl. This prevents air entrainment, which can cause problems in the downstream filtration process. Furthermore, flow control devices can be located downstream thus enabling implementation of an obstruction-free, full-bore feed arrangement.

Hygienic centrifuge design
Culturefuge is engineered using materials that meet stringent regulatory requirements for processing. To maintain hygienic operating conditions, this cell culture centrifuge can be automatically cleaned and sanitized without requiring major disassembly or assembly using Sterilization-in-Place (SIP) and Cleaning-in-Place (CIP) systems. In addition, flushing nozzles spray outside the centrifuge bowl, cyclone and inside the frame hood for maximum hygiene.

Product range

• Culturefuge 100 for pilot plants and small-scale production facilities with capacities ranging from 200 to 2,000 l/hr.
• Culturefuge 300 for production with capacities ranging from 2,000 to 8,000 l/hr.

MBPX 810H, fully hermetic
The MBPX 810H combines easy installation with superb separation performance. The hermetic design is achieved by a combination of a hollow-spindle inlet, a hermetic outlet and a separator bowl completely filled with liquid. The unique hermetic hollow-spindle inlet ensures the gentlest acceleration of particles, preventing them from lysing. It is ideal for mammalian cell cultures. The hermetic in- and outlet design also completely avoids air entrainment and other related problems with oxidization and foam.

Merco nozzle centrifuges are designed specifically to meet the separation needs of companies involved in starch processing. Built to cope with high solids loads, with a focus on better performance, low energy consumption and easy maintenance.

The Merco range of separators are different from conventional multi-purpose nozzle centrifuges, specially developed to meet starch processing requirements. These involve high solids loads and continuous discharge, combined with a need to avoid nozzle blockages.
Merco nozzle centrifuges are now widely used in the starch industry for processes that include primary starch separation, gluten thickening, mill stream thickening and the clarification of middlings. As part of this, they are used for classifying, concentrating and washing solids, and for clarifying liquids that contain relatively high concentrations of solids.
The key feature of the Merco design is a special recirculation system in which solids can be recirculated to the nozzles at the edge of the bowl, at the same time as wash water is added. This unique capability means users can adjust production settings while the system is in operation, simply by varying the nozzle draw-off.
The operator can change the split and the concentration by a simple adjustment of the underflow draw-off valve in the discharge line. This provides a uniquely efficient way to control the separation process by determining exactly how much underflow is to be removed, how much is to be recycled back to the rotor and how much wash water is to be added.
This also makes it possible to use large-diameter nozzles that can deal with variations in feed concentration, as well as helping prevent blockages. This in turn makes the unit more versatile, and makes it easy to vary procedures based on the characteristics of individual feed flows.
A wide range of different Merco models is currently available, with capacities of up to 1,000 tons per day.

Substantial savings on waste oil handling
PureDry cuts the cost of waste oil and solids handling by removing the maximum amount of water from the waste oil and concentrating the solids to super-dry sludge (typically 5-15 kg/24 h), thus eliminating oily waste and related disposal costs.
The efficiency of the system in terms of drying up oily waste streams means holding tank volumes for waste oil and waste water can be reduced, thus freeing up valuable space on board a ship or in a power plant.
Furthermore, waste fuel recovery is possible when FO waste are separated from LO waste (separate waste oil tanks) – fuel saving up to 2 % is possible.
Maintenance and service by Exchange
PureDry is supplied with an Exchange Kit, which includes a new separator insert (rotor and disc stack), a new XCavator, and a consumables kit. After one year, the crew replaces the separator insert as simply as replacing the insert in a filter, also replacing the XCavator. The used parts are returned to the nearest Alfa Laval Service Center, and the ship orders new Kits.
Integrated waste oil/bilge water treatment concept
In combination with Alfa Laval’s PureBilge system, PureDry forms a complete, integrated waste oil/bilge water treatment solution that can dry up all oily waste streams on the ship or in the power plant. PureDry separates out the oil, concentrates the solids to super-dry sludge which can be landed as dry waste, and sends the water to the bilge system. PureBilge then takes care of the fine polishing of the oily water prior to discharge overboard.

PureBilge is a fully automated centrifugal bilge water treatment system that cleans oily wastewater onboard vessels at sea. By effectively removing marine oil pollution, it makes bilge water safe for discharge overboard.

This reliable single-stage high-speed centrifugal separation system effectively cleans large bilge water volumes at sea as well as ashore without the use of chemicals, adsorption filter or membranes.
Cleaning efficiency
PureBilge generally achieves an oil-in-water content of less than 5 ppm. Performance has been proven under real-life operating conditions and is unaffected by sea heave, oil shocks or high solids loading.
Superior separation performance
PureBilge features a patented XLrator disc inlet, which gently accelerates the bilge water as it enters the separator bowl. This prevents the splitting of oil droplets and the formation of additional emulsions, which gives PureBilge a substantial edge over other centrifugal separation systems.
Certified and cost-effective
Certified according to IMO resolutions, MEPC.107 (49) and US Coast Guard document 46 CFR 106.50, PureBilge is designed for unmanned 24/7 operation.
No man-hours are required for operation or supervision. There’s also no reject to pump ashore and no need to transport land wastes such as filter elements, coalescence elements, active carbon, or flocculation deposits. This contributes to reduced operating costs.
Easy to install in any engine room
Designed for plug-and-play installation, PureBilge is a compact and factory-tested separator module that is easy to install in any engine room. Continuous operation means that there is no need for large bilge water holding tanks, which frees up space and increases payload capacity.
Fully automated monitoring and control
The new EPC 60 Bilge process controller is an easy-to operate, computer-based Alfa Laval process controller. It facilitates advanced fully automated monitoring and control of PureBilge functions by displaying in clear text process parameters, alarms and other data.

Alfa Laval X-series decanter centrifuges are designed to provide a cost-effective operation in the olive oil chain, for both two-phase and three-phase operation.

Design features and benefits
The decanters feature a special system called Variable Dynamic Pressure (VDP). The geometry of the bowl and conveyor allows for a high pressure to be made on the solids before the discharge, thus being able to reach a higher level of dryness. Through the electronic control of the conveyor speed (differential speed) the level of this pressure can be adjusted and set to obtain the required degree of dryness.
Two-phase and three-phase
It is possible to use the same decanter for both two-phase and three-phase operation, on the basis of the differences in specific gravity.
In the three phase operation, the special features of the bowl geometry allow to utilize the so called ARA system. The ARA system controls the specific regulation of the decanter liquid level that both optimize quality of oil and water consumption.
The higher clarity of oil separated through the three phase process can be obtained with the addition of a lower amount of dilution water. This ensures a higher oil quality and reduced fresh water consumption. For the same reason, AISI 316 stainless steel is used throughout, and the casings are also made of stainless steel.
The design includes hinged casings for easy opening, maintenance and cleaning.
The decanters also have an overload protection system in either electronic or mechanical release version.

Alfa Laval Y series decanter centrifuges are designed to provide cost-effective operation in the olive oil chain, specifically for two phase operation.

Design features and benefits
The decanters feature a special design for two phase operation. The geometry of the conveyor allows a good performance through:
Open and gentle feed zone design “Esbjerg” able to give maximum performance and wear resistance
Special flight for oil migration to the liquid outlet able to optimize yield and oil clarification avoiding turbulence
Special conveyor design to improve solids transportation and liquid separation
Tungsten carbide tiles on conveyor for Y9 and Y10. Optional for Y8. Special and exclusive wear protection able to significantly reduce maintenance cost of conveyor.
Through the electronic control of the conveyor speed (differential speed) the retention time can be adjusted and set to obtain the required degree of oil clarification. Electronic control of differential speed is done trough a variable frequency drive (VFD) directly connected to Alfa Laval's exclusive direct drive gearbox. This new setup makes it possible to reduce power consumption and wear due to transmission.
High quality stainless steel is used throughout, including hinged casings for easy opening, maintenance and cleaning.
The decanters also have an electronic overload protection system.

The final quality of the olive oil depends on the level of purity obtained from the final separator,
which makes the UVPX separators the ideal choice.

The UVPX separator lives up to the highest standards for efficiency and functionality. The design is based on criteria that include customer demands for gentle oil treatment, outstanding separation efficiency, easy installation and operation, and good serviceability.
Applications
The UVPX separator is designed for intermittent discharge of solids, while separating two intermixed and mutually insoluble liquid phases of different densities. It is most frequently used to clarify oil and to recover any traces of residual oil in the olive vegetable water.

Designed for palm oil clarification and purification, three-phase decanters in the PANX range offer maximum oil recovery with low energy consumption. They also enable mill owners to reduce effluents from their plants.

Purification or clarification of mineral oils used in marine installations and power stations (fuel and lubricating oils).

Separation takes place in a solids-retaining bowl that can be arranged for either clarification or purification. In both cases, the contaminated oil is fed into the separator through the centre, and it is separated by centrifugal force into its various phases, the heaviest phase (sludge and water) being forced outwards to the periphery of the bowl. The accumulation of sludge is periodically removed from the bowl by hand.

Installation
The oil is pumped, heated, and separated as shown in the figure. A liquid seal in the separator bowl prevents the oil from escaping through the water outlet. If this seal is broken, an alarm device is activated. With unmanned engine rooms, the
signals are transmitted to a remote control unit. When the seal is broken, the three-way valve shuts off the oil feed and the oil is recirculated until the fault is corrected.

Alfa Laval Centribone plants provide the most versatile and efficient way to process meat by-products.

The continuous wet rendering process can handle any raw material, from purely fatty tissues to the best gelatin bones. The low-temperature process is a totally closed system, especially suitable for processing edible products. With Centribone’s state-of-the-art processing, you can now move into more profitable segments in the market of end products.

High quality end products
To obtain the highest quality end products, the temperatures of fats, proteins and collagens must be kept as low as possible while processing. Centribone enables the production of high-quality fats, with outstanding colour, and no increase in free fatty acids (FFA) or peroxide value(s) and with very low moisture content. In the processing of pet foods or edible proteins, Centribone retains the highest possible nutritional values. The amino acid spectrum is virtually unaffected. This is due to the optimized heating programme – with the colour of the proteins and fats confirming its value. Centribone’s continuous processing makes it easy to maintain uniform quality. Producers benefit in terms of ease of operation – and customers appreciate the difference.

Flexible production planning
In reducing start-up and shutdown times, Centribone not only makes production more flexible and more efficient, but also allows more time in any production schedule. In a Centribone plant, for example, processing different raw materials such as fatty tissues and bone is possible in successive cycles, if
required. Whether you are a large-scale operator or a small one, your productivity is improved.

Short-time melting process
The minced material fed to the inlet of the raw material heater is led through the heater by a variable-speed conveyor. The holding time in the heater can be as short as five minutes, where the temperature is carefully controlled at 65–90°C (150–195°F), depending on the raw materials used and the end product desired. Rapid heating is achieved by injecting live steam directly into the raw material. Fully automatic control of the temperature profile can be obtained through built-in temperature sensors, available as optional instrumentation.

Low energy consumption
With Centribone, energy consumption is reduced by as much as 30%, compared with dry rendering methods. This is because the decanter and separator remove most of the process water mechanically. And, unlike conventional processes, Centribone becomes more economical to use as the water content of the raw material increases.

Flexible throughputs and layouts
Centribone plants can process a variety of raw materials at rated throughputs ranging from 3 to10 t/h. At higher throughputs, flexible twin-lines are normally recommended. Because of its logical, compact design, a Centribone plant requires minimum space. It can be easily fitted into existing buildings. In addition, it is easy to operate and maintain.

PureNOx is a complete water treatment system using a centrifugal separator to clean the wash water in the wet scrubber

PureNOx cleans the scrubber water in an Exhaust Gas Recirculation (EGR) process. EGR is one of the solutions under development for compliance with Tier III NOx reduction demands, which will apply to NOx Emission Control Areas starting in 2016. EGR has the potential to be the NOx abatement frontrunner, especially as it reduces fuel consumption when operating at Tier II.
PureNOx is a complete water treatment system using a centrifugal separator to clean the wash water in the wet scrubber, which operates in a closed loop apart from the bleeding off of additional water generated in the combustion process. Developed and undergoing testing in collaboration with MAN Diesel & Turbo, PureNOx will be commercially available in due time before Tier III legislation comes into force.
Cleaning of EGR scrubber water for engine protection
Cleaning of discharge water in compliance with IMO directives (MEPC 57/21 Annex 4)
Monitoring and logging of wash water in compliance with IMO directives
Control of pH level in the EGR process
Compact and simple installation as an integral part of a two-stroke diesel engine
Possibility to operate at very low engine loads
Reduction of maintenance costs for the EGR scrubber system

Benefits
Compared to other NOx emissions reduction systems, the EGR system offers these advantages:
Compact footprint and simple installation
The EGR system including Alfa Laval’s PureNOx WTS is designed as an integral part of the MAN two-stroke marine diesel engine.
Easy to operate and possible to operate at very low engine loads
A fully automated EGR control system ensures quick and correct response to engine load variations. Only a small amount of additives in form of NaOH is required, depending on the sulphur content in the fuel.
Lower maintenance costs of EGR scrubber system
Using the EGR with its integrated Alfa Laval PureNOx system is a reliable technique that effectively removes soot and thereby protects the engine.
Significantly reduced waste volumes for onshore disposal
PureNOx collects and discharges wash water solids as concentrated sludge into the sludge tank, while cleaning the scrubber water in compliance with IMO criteria for overboard discharge.
Protection of engine and environment
An Exhaust Gas Recirculation (EGR) system recirculates up to 40% of the exhaust gas into the charge air chamber. This lowers the combustion temperature, which directly reduces the formation of harmful NOx emissions. PureNOx not only prevents soot and compounds derived from the exhaust gas from accumulating in the EGR scrubber and corroding the engine, but also enables the bleed-off of clean water in compliance with IMO criteria.

The Clara range of self cleaning high-speed separators is specially developed for the food and beverage industries. In developing the Clara range, we emphasized gentle product treatment, high separation efficiency and low power consumption

The complete range for all needs
Within the Clara range there are models of all sizes, from laboratory or pilot-scale operation to models for large food or beverage plants with huge capacities. Depending on the model, the Clara separators are available in different designs, from non-hermetic (top fed) to fully hermetic (bottom fed) design.
The smaller models Clara 20, Clara 80 and Clara 200 are all skid mounted to facilitate installation, minimize footprint and make them mobile (all the skids have wheels). The skid has all the equipment needed for efficient and ­reliable operation of the separator. There is a control panel and a pipe rack ­containing all the necessary components to feed the separator with product and service water.
The larger models Clara 401, Clara 501, Clara 601 and Clara 701 are less suitable for skid mounting. Here, the electrical panels for starter and control panel are mounted on a stainless steel, self-­supported frame. Product and service water piping with all valves and gauges are mounted on the opposite side of the same frame.
Feed pumps and pumps for solids ­discharges are available as options for all Clara models. The larger Clara models also have capacity control as option.

Application areas
The Clara series is particularly well suited for clarifying products such as
white grape must (free run and press juice)
young wine (both still and sparkling types)
mature wine
tea extract
coffee extract
fruit juices (citrus, deciduous and tropical)
Features and benefits
The Clara separators have several ­distinct advantages, depending on the model.

Disc inlet - gentle product treatment
The disc inlet enables the feed to ­accelerate in a very gentle way. This increases separation efficiency and ­minimizes foaming.

Oxy-Stop - prevents oxygen pick-up
The liquid seal in the separator outlet prevents oxidation of the product and loss of volatile aromas or CO2.

Fully hermetic design - reduced power consumption
The fully hermetic design is achieved by a combination of a hollow spindle inlet, a hermetic outlet provided by a mechanical seal, and a separator bowl completely filled with liquid.
In addition to maximum separation ­efficiency and significantly reduced power consumption, the fully hermetic concept prevents any air-liquid interface, which otherwise is a source of foaming and food degradation.

Hollow spindle design - gentle acceleration
Our unique hollow spindle design ensures the most gentle acceleration of shear-sensitive particles. This leads to maximum separation efficiency and reduced power consumption at the same time.

Alfa Laval centrifuges for vegetable oil are continuously modernized to benefit from developments in materials, mechanical design and fluid dynamics. The VO range of low- and medium-sized separators are for continuous degumming, neutralizing, and washing.

VO separators are based on a simple, robust and well-proven, open design concept, and are easy to maintain. The design reduces the pressure drop across the separator and results in a low feed pressure requirement to the machine.

The bowls of the VO range are specifically designed for fatty oil separation. The geometry permits minimal pressure drop and high flow rates, and outlets are equipped with stationary paring devices for removal of the different phases. The paring device on the light phase is a fixed paring disc, while the paring device on the heavy phase is adjustable.

The diameter of the heavy phase paring device can easily be adjusted by changing the length of the paring tubes. This makes it possible to adjust the position of the separation interface in the disc stack, facilitating optimal separation.

With the working environment in mind, the VO separator range is designed to operate at low noise levels. This is achieved through a rubber-damped bearing assembly, and an outer bowl design engineered for low wind noise.

High capacity solids-ejecting centrifuge for the animal and fish processing industries, specially designed for extremely demanding separation jobs.

Key features of the AFPX range of centrifuges are their ability to handle high flow rates, high solids content and high-temperature processing. These functions make it the ideal choice to handle the tough conditions encountered in the animal and fish processing industries.
In addition, the AFPX 517 centrifuge combines a high G-force, high sludge capabilities and automated operation.

Applications
The AFPX was designed to discharge solids intermittently, while at the same time separating two intermixed and mutually insoluble liquid phases of different densities. The centrifuges comes in a series of optimized executions that are suitable for a considerable number of duties, including separating fish press water, stick water and extracts. Other applications include the purification of fish oil and liver oil, animal fat, peel oil, and similar products.

The Alfa Laval BTUX separation system has been specifically developed to ensure optimum separation and concentration efficiency in biotechnological applications.

The BTUX separators take advantage of the fact that the slurry of concentrated solids is pseudo-plastic and flows easily in the bowl against the centrifugal force. This means that the recovered solids can be obtained with a low demand on energy in a closed system under pressure. Therefore, the hygienic conditions are very good, further improved by a full-speed CIP procedure.

Unique Vortex nozzle design

Like the FEUX and MBUX separator models, the BTUX separator bowl is equipped with Alfa Laval´s unique vortex nozzles, which offers performance unmatched by conventional nozzle centrifuges. With the self regulating vortex nozzles the concentration of discharged solids phase can be kept at a high and even level irrespective of fluctuations in the feed flow or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clogging.

The BTUX separator system is designed for automatic ejection of washed-out solids during the cleaning cycle, which makes it particularly suitable for process lines equipped with automated cleaning-in-place (CIP).

A complete separation system

The BTUX is available in different sizes covering a wide range of process demands. A complete BTUX separation system consists of the BTUX separator, electric motor, solids cyclone, switch gear panel and starter, control panel, valve cluster, flow meter, sight glasses, flexible connections and other related equipment.

The Alfa Laval MBUX separators for recovery of yeast and other microorganisms take advantage of the fact that the slurry of concentrated solids is pseudo-plastic and flows easily in the bowl against the centrifugal force.This means that the recovered solids can be obtained with a low demand on energy in a closed system under pressure. Therefore, the hygienic conditions are very good and are further improved by a full-speed CIP procedure.

The MBUX separators are available in different sizes covering a wide range of process demands.

With the patented Alfa Laval self regulating vortex nozzles the concentration of discharged solids phase can be kept at a high and even level irrespective of fluctuations in the feed flow or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clogging.

The light and heavy phase are both discharged under pressure which prevents foaming and simplifies installation by eliminating pump systems and improves the hygiene. Solids pockets in the bowl guide the solids to the concentrate tubes, preventing accumulation of firmly packed solids and making separation and Cleaning In Place (CIP) easier and more effective.

Automated CIP at full speed

The bowl can be opened intermittently during production and/or the cleaning cycle for ejections of solids while the machine continues to run at full speed. Frame hood is fitted with a spray nozzle for washing the outside of the bowl.

The Alfa Laval Phoenix treatment system for contaminated water is an extremely versatile, modular process solution whose elements can be combined to meet many different needs.

When installed this ensures that it is able to efficiently treat virtually all kinds of oily, contaminated water from any offshore oil and gas operation.
Offshore rigs and production platforms – as well as other installations and vessels used in the oil and gas industry – operate with complex mixtures of oil, water and solids, often in large volumes. Most conventional technologies are incapable of effectively splitting the kinds of stable emulsions often found in mud contaminated oily waste water, or of removing suspended colloidal particles.
These complex streams of contaminated water vary considerably in composition and physical properties. However on a drilling rig, they almost always contain both hydrocarbon residues and solid particles – ranging from coarse to extremely fine. These mixtures are often in the form of complex emulsions that are difficult for traditional separation systems to tackle.
The new Alfa Laval Phoenix contaminated water treatment system combines our core centrifugal separation technologies with additional screening system and the use of environmentally responsible chemicals. The result is an extremely versatile, modular process solution whose elements can be combined to meet many different needs. This ensures that you are able to efficiently treat virtually all kinds of oily, contaminated water from your offshore oil and gas operations.
The Alfa Laval Phoenix system means
One single system for treating all kinds of contaminated water
Ideal combination of mechanical and chemical separation technologies
Less need for onboard storage, thus saving on space
Low overall processing costs
Reduced costs for transporting contaminated water to shore.
Compliance with requirements in the IMO Res. MEPC.107(49), ensuring an improved environmental profile.

The emmie comprises a trolley-mounted centrifugal separator and electrical oil heater for use on ships. Moved between marine hydraulic systems, it removes water and 99% of all 2-5 μm particles from oil, increasing oil service life and system reliability.

Increase marine hydraulic system reliability
The Alfa Laval emmie is a portable marine hydraulic oil cleaning system that effectively cleans hydraulic oil, removing both 99% of all 2 - 5 μm particles and 100% of the free water from oil used in hydraulic systems onboard ships. It meets the requirements for hydraulic oil cleaning in accordance to ISO Cleanliness Code 4406:1999 13/11/8.
Designed for use in systems such as CP propellers, steering gear and other marine hydraulic machinery, the emmie consists of a disc-stack centrifugal separator, which can operate in purifier mode and clarifier mode, and an electrical oil heater. By prolonging the service life of marine hydraulic oils, the emmie increases uptime, minimizes wear on maritime hydraulic equipment and reduces costs. In doing so, this portable ship hydraulic oil cleaning system generally pays for itself in less than a year.

Easy-to-use ship hydraulic oil cleaning system
Lightweight and compact, the Alfa Laval emmie is easy to use and does not require any alterations to marine hydraulic machinery. Connecting the emmie to a hydraulic oil tank takes just a few minutes. Then simply start the separator, start the pump and, after the oil flows through, start the heater. With its straightforward plug-and-play operation, the emmie mobile marine hydraulic oil cleaning system cleans the oil at a flow rate of 80 - 120 l/h. No supervision is required once the system has started.

Extended service lifetime
The Alfa Laval emmie effectively removes any water, airborne dust and particles from wear on paint, metal, plastic or rubber from marine hydraulic oils. By removing water from the oil, the emmie prevents system corrosion as well as oxidation and subsequent decomposition of oil additives, which reduce oil service lifetime. This not only prolongs the service lifetime of marine hydraulic oil, but also reduces oil consumption and costs.
In addition, by removing the particles from the oil, the emmie prolongs the service lifetime of hydraulic systems. Cleaner oils translate into more uptime – with fewer unscheduled production stops and fewer breakdowns due to solid particles that cause wear on parts and can clog equipment.

Reduced costs

Due to prolonged intervals between filter and oil replacements, the emmie drastically cuts operating and maintenance costs, including those related to the purchase of new hydraulic oil and the disposal of used filter cartridges and used oil.

Alfa Laval unparalleled decanter centrifuge technology has paved the way for a series of ground-breaking innovations, all based on proven technology renowned for reliability. Together, these ensure a unique combination of better performance and lower energy consumption, resulting in lower operating costs than ever before.
The ALDEC G3 is built around the Slimline design – a breakthrough in decanter centrifuge performance and capabilities. The smaller conveyor diameter makes room for more liquid in the pond, and allows higher bowl wall pressures, resulting in either drier cake or using less polymer.
Patented Alfa Laval Power Plates also effectively reduce the power consumption of ALDEC G3 decanter centrifuges, making a big contribution to cost savings.

Multiple benefits
The ALDEC G3 range ensures:
Lower power consumption (which also greatly reduces CO2 emissions)
10% boost in processing capacity – or drier cake
Reductions in life cycle costs
More efficient bio-solids handling
Better process monitoring and control
The ALDEC G3 decanter centrifuge design provides significantly improved separation results and better control of all the variables – using up to 40% less energy. Lower power consumption saves money as well as improving the environmental profile of any dewatering or thickening operation.

PureSOx H2O water cleaning unit is also available as a standalone product for use in wet scrubbers not designed by Alfa Laval.

Compact and modular, the PureSOx H2O water cleaning unit is an essential part of Alfa Laval’s PureSOx hybrid or freshwater scrubber. But it is also available as a standalone product for use in wet scrubbers not designed by Alfa Laval. Proven under real-life operating conditions, PureSOx H2O uses centrifugal separation to clean scrubber water in compliance with IMO legislation. The automated unit is easy to operate, and it is available in different sizes to suit a variety of flow rates. All equipment comes installed and tested on a common frame, which is divided into three main blocks to simplify retrofit installations.
