Abstract

A lot of predictive methods for predicting the high-pressure vapor-liquid equilibria have been proposed using cubic equations of state and excess free energy mixing rule. This paper deals with the proposal of MHV1-SA model that is obtained by combination of SRK cubic equation of state and MHV1 mixing rule with ASOG group contribution model. The high-pressure vapor-liquid equilibria for five systems have been predicted using ASOG group pair parameters for low pressure. The ASOG group pair parameters for 30 group pairs relating to group CO2 and CH4 have been then determined newly using high-pressure vapor-liquid equilibrium data. The high-pressure vapor-liquid equilibria for the systems containing carbon dioxide and methane have been predicted, and the comparison of this work has made with the predicted results using PSRK, LCVM, and PRASOG.
