Removal of amines from wastewater using membrane separation processes

Natural gas is one of the energy sources in the world. It consists of predominantly methane (CH4), ethane (C2H6), ethylene (C2H4), propane (C3H8) butane (C4H10), pentane (C5H12) and some impurities particularly hydrogen sulfide (H2S) and carbon dioxide (CO2) that need to be treated prior utilized.
