ABSTRACT
Isothermal vapor liquid equilibrium (VLE) data of the alternative 2,3,3,3-tetrafluoroprop-1-ene + 1,1,1,2-tetrafluoroethane + propane ternary mixture over the temperature range of 283.15-323.15 K at 10 K intervals were measured using a circulation type apparatus. The experimental VLE data were correlated by Wilson-RK model, NRTL-RK model and PR-WS-MUNIFAC model. All of the models can well present the experimental data. The average absolute relative deviation (AARD) of pressure are within 0.60% and the maximum average absolute deviation (AAD) of vapor mass fraction is 0.0154 for the PR-WS-MUNIFAC model. Based on the UNIFAC (Dortmund) method, the two new functional groups of C2H2F and CH2F were divided and the relevant group parameters were obtained by fitting the experimental data.
