They were the original type of scrubber developed for this purpose. There are several different types of wet scrubbers designed to remove various pollutants from exhaust gas streams. The main categories include: Spray tower scrubbers, Venturi scrubbers, and Packed-bed scrubbers.

Ducon Environmental Systems (Ducon), a unit of Ducon Technologies Inc., is a world leader in providing the most advanced technologies for air pollution control equipment, and environmental consulting services since 1938.
Ducon''s equipment including: wet scrubber, venturi scrubber, & baghouse filter, allows its users to comply with the latest government environmental regulations for control of gaseous and particulate emissions and also helps recover valuable products discharging to the atmosphere.

That''s why they penetrate so easily through most filters, contaminating industrial and commercial exhausts. Electrostatic Precipitation is one of the most efficient methods known for removal of submicron particles from contaminated air. Electrostatic Precipitator acts as a magnet, attracting unwanted particles from the passing air, resulting in a clean and less odorful discharge.
Ducon Industrial Electrostatic Precipitators are built for tough industrial and commercial applications. Heavy-gauge housings accommodate heavy-gauge electrostatic modules, the largest, heaviest and by far, the most powerful in its class. All units are furnished with safety interlock switches to prevent electrical shock. 3" deep bottom with drain for collected contaminants is standard. Ducon''s Dry ESP Model E-7 electrostatic precipitator is incredibly efficient. It will remove particles as small as 0.01 micron in size. Overall efficiencies for all particle sizesof 99% or higher are common in our unit.

In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants. Wet Scrubbers can be designed to collect particulate matter and/or gaseous pollutants. Ducon, known for its patented dynamic wet scrubbers include the UW-3 Dynamic Wet Scrubber. This compact, unitized wet scrubber with self-cleaning wet fan features high dust collection efficiency in minimum space with low water requirements. Rugged construction virtually eliminates maintenance problems.

Flue Gas Desulfurization, also known as FGD, is a set of technologies used to remove sulfur dioxide from exhaust flue gases in sulfur oxide emitting processes such as Coal Fired Boilers, Pulp and Paper Plants, Oil Fired Boilers, Diesel Generators, Power Plants, Industrial Boilers and Waste Incinerators. Wet Flue-Gas Desulfurization Systems, include Spray Towers, Chemical Absorption Towers, and Ventri Rod Absorbers.

Dry, and Semi Dry, Flue Gas Desulfurization Systems, include a spray dryer and a baghouse filter. Ducon supplies Semi-Dry Removal type Dry Flue Gas Desulfurization Systems as well as Dry Injection type systems. The SDR systems are custom designed to absorb gaseous pollutants.

In contrast to a wet scrubber, which apply energy directly to the flowing fluid medium, an electrostatic precipitator applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy. Ducon Electrostatic Precipitators, are for new applications, or upgrade of existing installations and replacement parts. operating installations at boilers of sizes up to 600 MW capacity. In many cases, Wet Precipitators are being used in coal fired power plants to control acid mist emissions after a WFGD.

Cyclone Separator: Fluid Catalytic Cracking, FCC is one of the most important refinery processes as it converts high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils to more valuable gasoline, olefinic gases, and other valuable products. Residue fluid catalytic cracking RFCC is used for upgrading heavy feedstocks to light products. Therefore, a properly designed and highly efficient FCC and RFCC cyclone system is extremely important to ensure refineries operate efficiently with reduced operating costs and remain competitive. Ducon has an ongoing record of hundreds of successful operating FCC cyclone installations since the 1970''s that operate reliably and maintenance free for years. Ducon secured numerous FCC Cyclone technology patents for 50 years.
