摘要：

The UNIFAC model is applied to the excess Helmholtz energy at constant packing fraction associated with the equations of state of Soave-Redlich-Kwong and of Peng-Robinson. The mixing rule thus defined is applied to vapor-liquid equilibria of mixtures containing methane, ethane, carbon dioxide, paraffinic and aromatic hydrocarbons, alcohols and ketones. Satisfactory accuracy is obtained in calculating the bubble-point pressures and the compositions of the phases in equilibrium.
