Résumé

Isothermal vapor-liquid equilibrium (VLE) data are presented for the system hexafluoropropylene (R1216) + propylene (R1270). Measurements were performed for six isotherms ranging from (263.17 to 353.14) K, at pressures from (0.224 to 4) MPa. The measurements were undertaken using a “static-analytic” type apparatus, with sampling of the equilibrium phases via pneumatic capillary samplers (Rolsi, Armine's patent). The apparatus and the samplers were developed in the CEP/TEP laboratory. The uncertainties in the measurements are within ( 0.02 K, ( 0.0005 MPa, and less than ( 4.0 % for temperature, pressure, and mole fractions, respectively. The full set of isothermal VLE data is correlated with the Peng-Robinson equation of state (PR EoS), incorporating the original Soave R function, with the Wong-Sandler mixing rule utilizing the nonrandom two-liquid (NRTL) activity coefficient model.
