A Vent Gas Scrubber System is a lightweight, portable, and easy-to-install solution designed for cost-effective pollution control from low-volume sources.It consists of a scrubber and a liquid gas separator, both readily available from stock.This system is ideal when it is undesirable to discharge entrained gas along with the scrubbing liquid.The liquid gas separator operates without causing a pressure drop, ensuring the scrubber's capacity remains unaffected. Utilizing gravity, the separator directs liquid to a bottom drain while the gas reverses direction by 180 degrees to exit through a top outlet.Its design allows low gas velocity for efficient separation.
