Solubility of mixtures of carbon dioxide and hydrogen sulfide in water + monoethanolamine + 2-amino-2-methyl-1-propanol

Solutions of amines are frequently used in gas treating processes to remove acid gases such as CO[sub 2] and H[sub 2]S from gas streams in the natural gas and synthetic ammonia industries and petroleum chemical plants. The solubilities of mixtures of carbon dioxide and hydrogen sulfide in water + monoethanolamine (MEA) + 2-amino-2-methyl-1-propanol (AMP) have been measured at 40 and 80 C and at partial pressures of acid gases ranging from 1.0 to 200 kPa. The ternary mixtures studied were 3 kmol/m MEA + 2 kmol/m[sup 3] AMP and 2 kmol/m[sup 3] MEA + 3 kmol/m[sup 3] AMP aqueous solutions. The Kent and Eisenberg model has been modified 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.
