This modified coordination number model was compared with other equations in literature. Better agreement with molecular simulation data for fluid mixtures is observed from this study. Pure fluid parameters for non-polar low molecular weight compounds and polymers are reported. Satisfactory calculated results for the saturated properties are obtained. VLE calculations on non-polar fluid mixtures and polymer solutions were investigated using the van der Waals mixing rules. The equilibrium pressures, solvent solubility and activity of various binary systems were evaluated. This EOS presents comparably good results in comparison with those from other engineering models. |
