PdT data for Propane + Hydrogen Sulfide from (263.11 to 363.24) K at pressures up to 40 MPa

Journal of Chemical & Engineering Data, 56(1), 84-88, 2011

Pressure, density, and temperature (PρT) data are presented for two compositions (z1 = 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−Plöcker 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 % on both liquid and vapor phases except for data close to the critical point.
