ABSTRACT
Isothermal vapor-liquid equilibrium (VLE) data for {tetrafluoromethane (R14) + ethane (R170)} were measured at (179.68, 190.14, 200.68, and 210.03) K. A recirculation-method apparatus was used in this measurement, in which a self-made electromagnetic recirculation pump was used to drive the vapor to accelerate the thermodynamic equilibrium process. The measured VLE data were fitted with the Peng-Robinson equation and the Huron-Vidal mixing rule. The calculated results were compared with the experimental data.
