Modeling of Solid – Supercritical Fluid Phase Equilibria of Asymmetric Systems by EOS – G ex Models

Solid – Supercritical Fluid Phase Equilibria of 2,3-Dimethyl Naphthalene, 2,6-Dimethyl Naphthalene, Anthracene, , Naphthalene and Benzoic acid with carbon dioxide have been modeled by using PRSV equation of state, Wong- Sandler mixing rule and NRTL activity coefficient. Calculated results are compared with experimental data , absolute average deviations and optimized binary interaction factors are determined and reported
