Caustic Fume Scrubber

Explanation

Caustic Scrubber is used for the removal of H2S and other acid pollutants from the exhaust gas. Caustic scrubber are mostly used in the treatment of refinery fuel gas, acid gas from amine units etc. Presence of CO2 is an important factor in design of Caustic scrubber.

Mechanism

Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. … If little or no CO2 is present, caustic scrubbing is traditionally done by contacting the gas with recirculated caustic solution in a packed tower.
