ABSTRACT

Isothermal vapor-liquid equilibria (VLE) data for the binary 1,1,1,2-tetrafluoroethane (HFC-134a) + 1,1,1,2,3,3,3 - heptafluoropropane (HFC-227ea) and 1,1,1-trifluoroethane (HFC-143a) + 2,3,3,3-tetrafluoropro-1-pene (HFO-1234yf) systems were measured at temperatures from 283.15 K to 323.15 K at 10 K intervals. The VLE experimental data for the HFC-134a + HFC-227ea system agree well with the literature data. The experimental data were correlated by using PR EoS with vdW mixing rule, and binary interaction parameters in mixing rules were optimized to fit the experimental data of each binary mixture. The comparison between the experimental data and the correlated results shows a good agreement.
