About Chemical Scrubbers
A chemical scrubber is an air pollution control device that uses a scrubbing liquid to remove harmful gases from an industrial exhaust stream. It works by forcing a contaminated gas stream through a liquid that absorbs and chemically neutralizes pollutants, such as sulfur dioxide (
