文摘

The vapor−liquid equilibrium (VLE) data for the binary system of R152a + R290 were measured with a recirculation method at five temperature points from (254.31 to 287.94) K. All of the data were correlated by the Peng−Robinson (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. The data were also compared with the results obtained from the literature. Azeotropic behavior can be found at the measured temperature range.
