Résumé

Isothermal vapor–liquid equilibrium (VLE) and vapor–liquid–liquid equilibrium (VLLE) data are presented for binary systems containing perfluorohexane (C 6 F 14) with carbon monoxide (CO) or hydrogen sulfide (H 2 S). Measurements were undertaken at three temperatures, viz. (293, 313, and 333) K, with pressures ranging from (0.322 to 24.497) MPa. An apparatus based on the " static-analytic " technique was used for the measurements. The equilibrium cell is equipped with a pneumatic capillary sampler, and equilibrium phase analysis is undertaken using a gas chromatograph. The uncertainties in the experimental measurements are 0.02 K, 0.0012 MPa, and 0.006 for temperature, pressure, and equilibrium phase mole fraction, respectively. The experimental data was modeled using the direct method using three different sets of thermodynamic models. The VLE data measured for the CO + C 6 F 14 system were correlated using the Peng–Robinson equation of state with the Mathias–Copeman alpha function and the Wong–Sandler mixing rule incorporating the NRTL (nonrandom two-liquid) activity coefficients model, while the VLE and VLLE data measured for the H 2 S + C 6 F 14 system were correlated using the Soave–Redlich–Kwong equation of state incorporating the Mathias–Copeman alpha function, and the MHV1 or MHV2 (modified Huron–Vidal first and second order) mixing rules utilizing the NRTL activity coefficient model.
