| Abstract | Abstract We report the measurement of high-pressure vapor–liquid equilibrium data for binary mixtures of carbon dioxide + n -octane, +methanol, and +ethanol systems at 313.14 K and carbon dioxide + perfluorohexane at 303.15–323.15 K. The experimental data were collected using a new simple apparatus for measuring high-pressure vapor–liquid equilibria and correlated using a modified SRK equation with the three-parameter conventional mixing rule proposed by Adachi and Sugie. The SAFT-VR equation of state has also been used to predict the phase behavior and found to be in good agreement with experimental data. For the carbon dioxide + methanol, carbon dioxide + ethanol and carbon dioxide + perfluorhexane systems simple Lorentz–Berthelot combining rules can be used to determine the cross interactions and predict the phase behavior. For the carbon dioxide + n -octane system cross interaction parameters fitted to experimental data are needed in order to capture the non-ideal phase behavior exhibited by this system. |
