ABSTRACT
Isothermal vapor-liquid equilibrium (VLE) data for the binary mixture of methane (R50) + tetrafluoromethane (R14) were measured at (159.61, 161.58, 169.38, 173.90, and 178.93) K. The experiments were carried out with a recirculation-method apparatus including the measurements of temperatures, pressures, and compositions of the liquid and vapor phases. The experimental VLE data were correlated by the Peng-Robinson equation with the Panagiotopoulos-Reid mixing rule and its modified form. The calculated results by these two models were compared with the experimental data.
