摘要：
The isothermal vapor-liquid equilibrium (VLE) for tetrafluoromethane (CF4) + propane (C3H8) system was measured and P, T, and y data were collected at temperatures of (142.96, 163.07, 183.10, 203.26, 223.17, 243.12, 263.15, 283.01, and 293.23) K. A vapor recirculation method was employed to drive the mixing of the two components in the system and to quicken the equilibrium process. The experimental results were correlated with Peng-Robinson equation of state and the van der Waals two-parameters mixing rule. The mean deviations between the correlated and measured vapor compositions were found to be satisfactory within 0.01 and the data showed a good accuracy and consistency.
