The removal of acidic gases such as CO{sub 2}, H{sub 2}S, and COS from gas streams is an important operation in the natural gas and synthetic ammonia industries, oil refineries, and petrochemical chemical plants. The solubilities of mixtures of carbon dioxide and hydrogen sulfide in water + diethanolamine (DEA) + 2-amino-2-methyl-1-propanol (AMP) have been measured at 40 C and 80 C and at partial pressures of acid gases ranging from 1.0 to 200 kPa. The ternary mixtures studied were 30 mass % AMP, 6 mass % DEA + 24 mass % AMP, 12 mass % DEA + 18 mass % AMP, 18 mass % DEA + 12 mass % AMP, 24 mass % DEA + 6 mass % AMP, and 30 mass % DEA aqueous solutions. The model of Deshmukh and Mather (1981) has been used to represent the solubility of mixtures of CO{sub 2} and H{sub 2}S in the ternary solutions. The model reasonably reproduces the equilibrium partial pressures of CO{sub 2} and H{sub 2}S above the ternary solutions for the systems tested.
