PρT Data for Hydrogen Sulfide plus Propane from (263 to 363) K at Pressures up to 40 MPa

Pressure, density, and temperature (P rho T) data are presented for two compositions (z(1) = 0.2227 and 0.2691) of the hydrogen sulfide (1) + propane (2) binary mixture at three temperatures in vapor and liquid states from a vacuum up to 40 MPa. Experimental work was achieved thanks to a vibrating-tube densimeter using the forced path mechanical calibration model (FPMC). The Lee-Kesler-Plocker model was chosen with one temperature-dependent binary interaction parameter to represent our experimental data. Observed deviations on liquid and vapor densities (between experimental and calculated data) are less than 2 To on both liquid and vapor phases except for data close to the critical point.
