Liqui-Mem is a membrane contactor used for gasification of water and wastewater, as well as gas separation, especially in the refining and petrochemical industries. This device utilizes innovative membrane technology that allows for efficient contact between two fluid phases, offering high surface area and low volume for effective gas transfer. It addresses significant challenges in these industries, such as treating spent caustic (harmful wastewater), removing carbon dioxide from valuable gases like hydrogen and methane, and purifying flue gases. Liqui-Mem enhances the value in refining and petrochemical processes by separating gases (like CO2 from others) and neutralizing harmful wastewater. Moreover, it offers several advantages over traditional methods in industries like fish farming and greenhousing, improving gas transfer processes.
