Abstract

The Perturbed Anisotropic Chain Theory (PACT) is used to model the vapor pressure and liquid density of pure CFC and HCFC compounds, and the vapor-liquid equilibria of binary and ternary CFC and HCFC mixtures and CFC/HCFC-hydrocarbon mixtures over a wide range of temperature and pressure. The phase behavior of nineteen binary and three ternary mixtures is predicted with very good accuracy compared with experimental data. Two widely used cubic equations of state, the Peng-Robinson and the Soave-Redlich-Kwong equations, are used for comparison. The overall deviation between cubic equation predictions and experimental data is twice the deviation between PACT predictions and experimental data. Using one temperature-independent binary adjustable parameter excellent correlation of the experimental data is obtained for all three equations.
