Solubility of H2S, CO2, CH4 and C2H6 in sulfolane at elevated pressures

The solubility of hydrogen sulfide, carbon dioxide, methane, and ethane in sulfolane [C.A. Registry No. 126-33-0] has been determined at temperatures in the range 25° to 130°C at pressures up to 7.6 MPa. The experimental results were correlated by the Peng-Robinson equation of state, and interaction parameters have been obtained for these systems. The parameters in the Krichevsky-Ilinskaya equation were obtained from the interaction parameters of the Peng-Robinson equation.
