<P> Scrubber systems (aka Chemical Scrubbers, Gas Scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and / or gases from industrial exhaust streams . The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used till today . Traditionally, the term "scrubber" has referred to pollution control devices that use liquid to wash unwanted pollutants from a gas stream . Recently, the term has also been used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to "wash out" acid gases . Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases . Scrubbers can also be used for heat recovery from hot gases by flue - gas condensation . They are also used for the high flows in solar, PV, or LED processes . </P> <P> There are several methods to remove toxic or corrosive compounds from exhaust gas and neutralize it . </P>
