摘要：

The isothermal vapor-liquid equilibrium (VLE) for tetrafluoromethane (CF4) + propane (C3H8) system was measured and P, T, 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 used to achieve quick equilibrium. The temperatures were measured with Pt100 platinum resistance thermometers and the uncertainty was less than ±0.005 K. The pressure was surveyed by two absolute pressure transducers, one by Keller PA33 pressure transducer with a full scale of 2 MPa and uncertainty of ±200 Pa, and the other by Mensor 6100 with a full scale of 10 MPa and uncertainty of ±1 kPa. The mixture composition measurement was performed by using a gas chromatograph (Agilent HP 6890N). After careful calibration, uncertainty was within ±0.002 in mole fraction over the whole range of concentrations. The experimental results were correlated with the 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 satisfactory as 0.011 and the data showed good accuracy and consistency. © All Rights Reserved.
