Abstract
The ASOG group contribution method for calculating the excess Gibbs energy at low pressures has been combined with the recently developed zero pressure MHV mixing rules of Michelsen for cubic equation of state. By using these models, high pressure vapor-liquid equilibria were predicted for 7 systems containing mostly polar substances. A comparison was made with the performance of the models which use the UNIFAC group contribution method, and in all tested cases the predictions were found comparable. The results indicate that the built-in temperature dependence of the ASOG method allows a reliable extrapolation well into high temperature region
