Type


	Process
	Your choices are...
	Drum Evaporator		Drum evaporators encapsulate 55 gallon drums and apply heat to the outside to evaporate the contents.
	Falling Film		In a falling film, evaporator liquid feed enters at the top, flows downward inside the steam-heated tubes in the form of a film, and leaves from the bottom.
	Fluidized Bed		Fluidized bed evaporators are used and suitable for concentration of liquid which exhibit severe fouling. They operate on forced circulation principle and are characterized by fluidized bed calandria. In its tubes, particles (e.g., glass pellets, ceramic particles or steel cylinder particles) are put into motion by the liquid flowing upwards and are eventually discharged into discharge chamber.
	Forced Circulation / Crystallizer		The liquid feed is pumped into the steam-heated tubes at the bottom. The liquid is superheated as the static head is reduced during flow from the heater to the vapor separator and it flashes into a mixture of vapor and liquid. The liquid returns to the pump inlet where it is re-circulated. Vapor leaves the top of the evaporator. This type of evaporator is ideal for concentration of viscous liquids with high specific gravity or liquids that tend to form scaling. Forced circulation evaporators are also known as crystallizers.
	Plate		Plate evaporators are of compact design. Instead of tube bundles, framed plates are used as the heating surface. These plate assemblies are similar to plate heat exchangers, but are equipped with large passages for the vapor flow. In these units a product plate and a steam plate are connected alternately. The product passage is designed for even distribution of liquid on the plate surfaces and low pressure drop in the vapor phase.
	Rising Film		Rising film evaporators are also known as natural circulation evaporators or climbing film evaporators. In a rising film evaporator, the liquid feed enters the bottom of the steam-heated tubes. The parallel movement of liquid and vapor along the tube surface causes effective water evaporation from the liquid feed. This type of evaporator is ideal for liquids, which attain high viscosity or have a fouling tendency.
	Rotary		Rotary evaporators (also called "rotavaps") are used to remove solvents from reaction mixtures and can accommodate volumes as large as three liters. They are found in almost every organic laboratory. A typical rotary evaporator has a heatable water bath to keep the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal. Most labs use a simple water aspirator vacuum on their rotavaps, so a rotavap cannot be used for air and water-sensitive materials unless special precautions are taken.
	Scraped Surface		Scraped surface evaporators are designed for the evaporation of highly viscous and sticky products, which cannot be otherwise evaporated. This type of evaporator has been specially designed to provide a high degree of agitation as well as scraping the walls of the evaporator to prevent deposition and subsequent charring of the product.
	Short Path		The short path evaporator, with internal condenser, combines evaporator and condenser in a single apparatus. This eliminates pressure losses caused by piping. Therefore, the distance between evaporation and condensation is extremely short. Short path distillation is used for the gentle separation of materials at the lowest possible temperature.
	Thermal		Thermal evaporation relies upon the boiling of wastewater at atmospheric pressure. There are numerous designs with distinct differences in efficiency, performance, maintenance and safety issues. Because the evaporation rate is based upon the introduction of heat into the wastewater, thermal evaporation is likely to be the most consistent and reliable type of evaporation. The sources of energy are typically natural gas, propane, steam or electricity.
	Thin Film		A thin film evaporator consists of a jacketed cylindrical heating section, a top vapor section with an entrainment separator, a top cover with mechanical seal housing and roller bearings, and a bottom conical section housing the lower bearing.
	Vacuum Distillation		Vacuum distillation utilizes a simple principle. Under vacuum, water boils at a much lower temperature than 212°F (boiling temperature at normal atmosphere). This lower boiling temperature can eliminate chemical degradation that typically occurs at 212°F. The manufacturer can also recover and re-use, if desired, the large water phase (steam vapor) that has been evaporated and condensed. The re-use of the water phase is a standard alternative for all wastewater applications and is often the reason that vacuum evaporators are chosen for large volume applications. A lower boiling temperature can provide significant benefit to generators with fitting applications and waste recovery objectives. During evaporation, the waste chemicals can be concentrated without destroying their chemistry, and the chemicals then can be re-used in the manufacturing process.
	Wiped Film		In a wiped film evaporator highly viscous and sticky products are processed. In a roto film evaporator viscous liquid can be concentrated by forming a thin film of the liquid, which the rotor scrapes away as evaporation occurs.
	Other		Other unlisted technology type.

	Features
	Your choices are...
	Atmospheric		An atmospheric evaporator sprays the wastewater onto a contact medium with a high-surface area. A high-volume air stream then passes through this medium, allowing the air stream to be "humidified" and then carried away. The air or the water must typically be heated in order to increase the air's capacity to hold moisture. Because of the spraying action, the wastewater must be fairly clean in order to minimize clogging of nozzles and fouling of the contact medium.
	Mechanical Vapor Recompression		In evaporators with MVR, the heating medium in the first effect is vapor developed in the same effect, compressed to a higher temperature by means of a high-pressure fan (MVR). Any excess vapor from the high heat section is condensed or may be utilized in a high concentrator. The condensate temperature is, however, too low for further beneficial waste heat utilization.
	Thermal Vapor Recompression		In multiple-effect evaporators with TVR, the heating medium in the first calandria is the product vapor from one of the associated effects, compressed to a higher temperature level by means of a steam ejector (TVR). The heating medium in any subsequent effect is the vapor generated in the previous calandria. Vapor from the final effect is condensed with incoming product, supplemented by cooling water if necessary. The condensate can be used a boiler feedwater, CIP liquid, or for preheating the drying air of an associated spray dryer.
	Horizontal		The evaporator has a horizontal configuration.
