An extension of the SAFT-VR Mie equation of state is proposed to predict the properties of multipolar fluids. The new model, referred to as multipolar M-SAFT-VR Mie, incorporates the general multipolar term developed by Gubbins and coworkers, which accounts for dipole−dipole, quadrupole−quadrupole, and dipole−quadrupole interactions. A modification of the third order terms in the perturbation theory results in an accurate description of the simulation data for multipolar Lennard-Jones fluids. Both the M-SAFT-VR Mie and polar soft-SAFT models are extended to account for polarizability, and a good agreement is obtained with molecular simulation data. The M-SAFT-VR Mie model is applied to refrigerant systems, and it is found that including both dipole and quadrupole moments in molecular models leads to more accurate results than using only a dipole moment. The new model provides excellent predictions of the vapor−liquid equilibria of zeotropic and azeotropic refrigerant mixtures without the need for binary interaction parameters, making it a valuable tool for formulating low-GWP working fluids.

Isothermal vapor−liquid equilibria (VLE) for eight binary systems involving R1233zd(E) [R1233zd(E) + n-butane, R1233zd(E) + CO 2 , R1233zd(E) + HCl, R1233zd(E) + R134a, R1233zd(E) + R152a, R1233zd(E) + R245fa], and R1233xf (R1233xf + R134a, R1233xf + R152a, R1233xf + R245fa) were measured at temperatures from 263 to 353 K. The experiments were conducted by means of a static analytic apparatus with phase analysis via gas chromatography, with the resulting maximum expanded uncertainties of 0.2 K for temperatures, 10 kPa for pressure, and 0.04 for vapor and liquid mole fractions. The main advantage of the equipment is that vapor and liquid samples were taken from vapor and liquid phase by two capillary samplers (ROLSI®). The Peng−Robinson equation of state and a modified Patel−Teja equation of state were both considered to represent the experimental data. If possible, comparison between the new experimental data and prediction with REFPROP 10.0 software were realized.
