Abstract

The capability of the CORGC equation of state for prediction of liquid density of multicomponent mixtures has been tested. In order to improve its accuracy, a new set of mixing rules has been developed which gives better predictions than the best available correlations. The average of absolute deviation for 25 multicomponent systems of nonpolar was only 0.67% and 2.7% for 5 slightly polar systems.
