Measurement of vapor-liquid equilibria for the binary mixture of propylene(R-1270) + HFC-134a |
| 초록 |
Isothermal vapor-liquid equilibria data for the binary mixture of propylene (R-1270) + HFC-134a at five equally spaces temperatures between 273.15 and 313.15K were measured by using a circulation-type equilibrium apparatus. The experimental data were correlated with the Peng-Robinson equation of state (PR-EOS) combined with the Wong-Sandler mixing rule. It was confirmed that the data calculated by this equations of state have a good agreement with experimental data. The experimental azeotropic points at investigated temperatures of this mixture were compared with ones calculated from the simple equation gotten from the fundamental equation of phase equilibrium and NRTL activity coefficient model. The result indicates that there was a small different between experimental azeotropic points and calculated ones corresponding to nonrandomness parameter α12 equaling to 0.2. |
