The University of Alberta has measured the solubility of CO/sub 2/ and H/sub 2/S in a Sulfinol solution at 104/sup 0/ and 212/sup 0/F (40/sup 0/ and 100/sup 0/C) to provide equilibrium data on the Sulfinol process. The solvent consisted of sulfolane (a physical solvent) together with diisopropanolamine (DIPA, a chemical solvent) and water. Partial pressures of CO/sub 2/ ranged from 0.35 to 825 psi (2.4 to 5688 kPa), while partial pressures of H/sub 2/S ranged from 0.67 to 560 psi (4.6 to 3862 kPa). Present results show that at high partial pressures, the effect of the physical solvent, sulfolane, leads to high solubilities of the acid gases in the liquid, making Sulfinol solutions attractive solvents at acid-gas partial pressures of 110 psi (760 kPa) or greater.
