Abstract
Abstract Ponce-Ramirez, L., Lira-Galeana, C. and Tapia-Medina, C., 1991. Application of the SPHCT model to the prediction of phase equilibria in CO 2 -hydrocarbon systems. Fluid phase Equilibria , 70: 1-18. A simplified version of the Perturbed Hard-Chain Theory (SPHCT) of Kim et al. is applied to the computation of the vapor-liquid equilibrium of binary systems of the type CO 2 -hydrocarbon at different temperatures of interest to the oil industry. The molecular parameters required for 70 components of the four homologous series of hydrocarbons (paraffins, olefins, naphthenes and aromatics) and other fluids of industrial interest are reported. Very satisfactory results are obtained with this model.
