Abstract
Bae H.-K., Lee S.-Y. and Teja A.S., 1991. A method for the prediction of critical temperature and pressure of pure fluids. Fluid Phase Equilibria, 66: 225-232. The critical temperatures and pressures of 213 organic compounds have been estimated using the Peng-Robinson equation of state, based on a knowledge of the van der Waals volume, normal boiling point and acentric factor of the substances. Comparisons with the group contribution methods of Lydersen and Ambrose are shown and the average absolute deviations between the experimental and calculated properties according to the present work, the Lydersen method and the Ambrose method are 0.52, 0.91 and 0.70%, respectively, for critical temperature, and 4.87, 5.82 and 3.84%, respectively, for critical pressure.
