چکیده انگلیسی
The vapour-liquid phase equilibrium was measured using an apparatus based on the recirculation method for the 2,3,3,3-tetrafluoroprop-1-eneâ+âpropane binary system. A total of 55 data points were obtained over the temperature range from 253.150 to 293.150âK. The experimental standard uncertainties were less than 5âmK for the temperature, 800âPa for the pressure, and 0.005 for the mole fraction. The experimental data were correlated by the PR-VDW model and PR-HV-NRTL model. Both models can present the experimental data well and the PR-HV-NRTL model achieves a higher degree of precision. The relative deviations of pressure are within ±0.50% and the maximum absolute deviation of vapour mole fraction is 0.006 for the PR-HV-NRTL model. A positive azeotropic behaviour can be observed for the binary system.
