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 X-SFL = 0.0113 to X-SFL = 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. (C) 2016 Elsevier Ltd.
