Experimental investigation of hydrogen sulfide solubility in aqueous sulfolane solution

New experimental data are presented for the solubility of hydrogen sulfide in aqueous sulfolane solution which is an important topic in many areas of chemical engineering. Solvent mixtures of (SFL + H2O) contain the composition range from xSFL = 0.0113 to xSFL = 0.939, temperatures from (303.15 to 353.15) K with step 10 K and total pressures up to 2.0 MPa. Henry's constant of H2S in pure SFL, pure H2O and mixed (SFL + H2O) are reported on the mole fraction and molality base. Model for the Gibbs excess energy of mixed solvent is used to correlate the obtained experimental data.
