Résumé

_______________________________________________________________________ In this study, we present new experimental data of vapor-liquid equilibrium for the binary system trifluoromethane (R23) + 2,3,3,3-tetrafluoropropene (R1234yf), measured at 254.10, 273.43, 293.24, 303.17, 318.08, 332.97, and 348.40 K and at pressure ranging from 0.1568 to 4.3553 MPa. A " static-analytic "-type apparatus is used to do the measurements, with sampling of the equilibrium phases via capillary sampler (ROLSI TM). We used two different methods to model the obtained isothermal P-x-y data: 1) the Peng-Robinson cubic equation of state, incorporating the Mathias-Copeman alpha function, combined with the NRTL excess free energy model and Wong-Sandler mixing rules, and 2) the PC-SAFT equation of state. Both models show a very good agreement with the experimental data. ________________________________________________________________________
