A Dry Scrubber Unit is a type of air pollution control system that is used to remove pollutants from industrial exhaust gases. It works by using a dry sorbent material to adsorb or chemically react with the pollutants in the gas stream, before releasing the cleaned gas back into the atmosphere. The Dry Scrubber Unit typically consists of a series of chambers or beds filled with a sorbent material, such as activated carbon or lime.ï
