The accuracy of these approaches in predicting equilibrium temperatures at given pressures (635 experimental data with T = 220 ? 413.97 K and P = 0.05 ? 48.35 MPa), liquid phase compositions, and liquid molar volumes was examined and compared to provide an overview on their performance. The recently developed PR + COSMO-SAC EOS was found to be most accurate, with deviations of 6.25 K in temperature, 0.071 in liquid mole fraction, and 21% in liquid molar volume. The performance of these models can be very different for the solid containing different functional groups. Nevertheless, the PR + COSMO-SAC EOS could provide useful a priori predictions with only input of experimental heat of fusion and melting temperature of the solid. ? 2017 Elsevier B.V.Carbon dioxideCOSMO-SACModified Huron-Vidal mixing rulePeng-Robinson equation of stateSolid-liquid-gas equilibriumWong-Sandler mixing rulejournal article10.1016/j.supflu.2017.08.0082-s2.0-85032828224https://www.scopus.com/inward/record.uri?eid=2-s2.0-85032828224&doi=10.1016%2fj.supflu.2017.08.008&partnerID=40&md5=60eb6b9d51a2c7fcce449b285b3ab08d
