To develop a widely applicable method for predicting high-pressure vapor-liquid equilibria by the equation of state, a mixing rule is proposed in which mixture energy parameter "a" of the Soave-Redlich-Kwong, Peng-Robinson, and Martin cubic equations of state is expressed by using the ASOG group contribution method. The group pair parameters are then determined for 14 group pairs constituted by six groups, i.e. CH4, CH3, CH2, N2, H2, and CO2 groups. By using the group pair parameters determined, high-pressure vapor-liquid equilibria are predicted with good accuracy for binary and ternary systems constituted by /i-paraffins, nitrogen, hydrogen, and carbon dioxide in the temperature range of 100-450 K.
