Pressure, density, and temperature (PρT) data are presented for ethane (1) + hydrogen sulfide (2) at z2 = (0.0380, 0.0563, 0.0977, and 0.1430) and various temperatures in the (254.05 to 363.21) K range. A vibrating tube densimeter, with the forced path mechanical calibration model, was used to determine both PρT data and vapor−liquid equilibrium (VLE) even when the mixture is close to its critical temperature. PρT and VLE results were correlated with the Benedict−Webb−Rubin−Starling's equation of state (BWRS EoS), the re-evaluated pure component parameters, and the mixing parameters derived using Starling's generalized mixing rules. Finally, we have compared, in VLE conditions, the BWRS EoS to a Peng−Robinson EoS using quadratic mixing rules.
