Abstract

The combined acid gas removal and water filtration system () removes sour gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2), from an input gaseous hydrocarbon stream (FG), as well as producing purified water (TW). The acid gas removal system () has a contactor () for contacting the input gaseous stream (FG) with an absorption liquid solvent (ALS), and a stripper () for recycling the absorption liquid solvent (ALS) and removing acidic gases (AG) therefrom. A first heat exchanger () heats used absorption liquid solvent (UALS) output from the contactor () prior to injection into the stripper (). A second heat exchanger () cools recycled absorption liquid solvent (RALS) using a refrigerant (R) before injection back into the contactor (). The refrigerant (R) is coupled with an absorber (), which receives a dilute ethanolic draw solution (DDS) from a forward osmosis filtration system (), producing purified water (TW).
