It is common industry practice to utilize various amines to remove acid gases such as H2S or C02 from hydrocarbons with low molecular weight. The amines most commonly
used include Methyl Ethanol Amine (MEA), Diethanol Amine (DEA), and Methyl Diethanol Amine (MDEA). Aqueous solutions of these amines form complexes with acid gases which, with the application of heat, can be broken reversibly.
