A scrubber (or fume scrubber) is an air pollution control device designed to remove certain gases, vapors and fumes from the air stream from an industrial facility. A scrubber, also known as a chemical scrubber, typically sprays a scrubbing liquid in special scrubbing towers to absorb, dissolve or chemically react gaseous phase contaminants and contaminants into the absorbed flue gases before being vented to the atmosphere.
