Abstract

The purpose of this paper is to evaluate the effect of five different mixing rules on the calculated thermodynamic properties including vapor pressure, density and excess property of several binary mixtures. These properties are calculated by ISM (Ihm-Song-Mason) and PHS (Perturb Hard Sphere) equations of state (EOS). Also we use two interaction parameters, Kij to improve the results. The results indicate that mixing rules can effect on predicted thermodynamic properties. The Fit (MADAR-1) mixing rule gives more acceptable values. when the mixture components are similar in size, different mixing rules often do not change the errors in calculated properties more than 2%-1%. However, as the size similarity decreases, the effect of applied mixing rules becomes more important.
