Amine gas treating, also known as gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove H2S and CO2 from gases. They are known as regenerative chemical solvents. It is a common unit process used in refineries, and it is also used in petrochemical plants, natural gas processing plants, and other industries.

Oil refinery wastewater is well-known in potentially contaminating groundwater and surface water. Wastewater in oil refinery, which originates from processes such as pyrolysis oil, amine gas treating, alkalization of the crude oil and contains a large quantity of sulfide sulfur, is called sulfur-alkaline waste (SAW). It is classified as a hazardous material. The substance has a significantly high chemical oxygen demand, of which the majority comes from inorganic sulfides, with 2000 mg L−1 of sulfide concentrations (Kuhn et al., 1983). Therefore, we need to pay more attention to the treatment of SAW.
