摘要
(Vapor + liquid) equilibrium (VLE) data for a binary system of {1,1-difluoroethene (R152a) + trans-1,3,3,3-tetrafluoropropene (R1234ze (E))} were measured by a static-analytic method at temperatures ranging from 258.150 to 288.150 K. All data were correlated by the Peng–Robinson equation of state (PR EoS) with the Huron–Vidal (HV) mixing rule involving the nonrandom two-liquid (NRTL) activity coefficient model. The correlated results show good agreement with the experimental data at each temperature point. The maximum average absolute relative deviation of pressure is 0.17%, while the maximum average absolute deviation of vapor phase mole fraction is 0.0020. Obviously the binary mixture is a zeotropic system at the measured temperature range.
