ABSTRACT
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.
