Vapor Liquid Equilibria

The perturbed-chain statistical associating fluid theory (PC-SAFT) is used to correlate and predict the phase equilibria and the triple point pressure of CO2 and ethanol binary mixtures. The binary interaction parameters (kij) are regressed by fitting to the experimental data of mixtures. The vapor-liquid equilibria and liquid-liquid equilibria of the mixtures are investigated and the influence of temperature and pressure on the phase equilibria and the triple point pressures is demonstrated. Our results show that the pressure dependent kij can describe the phase equilibria of CO2- ethanol mixtures quantitatively well.
