A simple and predictive for describing the high P-T vapour-liquid equilibria (VLE) of binary mixtures is described. It is based on the use of group contribution method such as UNIFAC combined with the Redlich-Kwong-Soave (RKS) equation of state (EOS) and quadratic mixing rules. VLE data are generated by UNIFAC at a prefixed temperature. These data are used for determining by regression analysis the binary interactin parameters of the RKS/EOS. Then the EOS with the same parameters can be used for describing VLE at higher temperatures.
