Measurement of VLE (TPx or TPxy data) for hydrogen sulfide + (dimethylsulfide or ethylmethylsulfide or carbon disulfide) and methane solubilities in (dimethylsulfide or ethylmethylsulfide or methylmercaptan or ethylmercaptan)

VLE data (gas solubilities (TPx data) or complete TPxy data) were measured for the following systems:•hydrogen sulfide (H2S) + dimethylsulfide (DMS) at 278, 293, 313, and 333 K.•H2S + ethylmethylsulfide (EMS) at 293 and 313 K.•H2S + carbon disulfide (CS2) at 273, 298, 323, and 348 K.•methane (CH4) + DMS at 253, 273, 293, and 313 K.•CH4 + EMS at 248, 273, 293, and 313 K.•CH4 + methylmercaptan (MM) at 243, 258, 273, 293, and 298 K.•CH4 + ethylmercaptan (EM) at 273, 293, and 313 K.These data were used to establish new binary interaction parameters for the predictive Soave–Redlich–Kwong (PSRK) group contribution of state. The extension of the PSRK parameter matrix allows now to perform reliable phase equilibrium calculations for systems with any hydrocarbons and sulfur compounds. The mean relative deviation of PSRK compared to the experimental data for the bubble point pressures is less than 2% and the mean absolute deviation for the vapor phase composition is 0.03 in terms of mole fraction.
