The removal of the acid gases, H{sub 2}S and CO{sub 2}, from refinery and natural gases is necessary to meet the specifications on the small amount of H{sub 2}S and CO{sub 2} remaining after treatment. The solubility of H{sub 2}S and CO{sub 2} in an aqueous solution containing 45 mass % 2-piperidineethanol, 40 mass % sulfolane, and 15 mass % water has been determined at 40 and 100 C. Partial pressures of H{sub 2}S ranged from 0.02 to 5,550 kPa and partial pressures of CO{sub 2} ranged from 0.002 to 18,900 kPa. Additional data for CO{sub 2} were obtained at 25, 70, and 130 C. Data were also obtained for mixtures of H{sub 2}S and CO{sub 2} in this solution at 40 and 100 C.
