Gas Scrubber

Gas scrubber are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. Gas scrubbers are commonly used to help control emissions of gases into the atmosphere. The basic wet scrubber consists of a vessel with adequate cross-sectional area to provide the correct air velocity, a depth of packing media for distributing scrubbing solution like caustic or base solution that can capture and neutralize the gases, recirculation system to provide the correct volume of solution throughout the packing and a demister pad or mist eliminator to prevent excess scrubbing solution from re-entraining into the exhaust stack.
