主　　题：Liquid-vapor equilibrium fugacity coefficient activity coefficient azeotrope distillation. 

摘      要：The current paper deals with the way in which the liquid-vapor equilibrium can be predicted, using the program Microsoft-Excel to obtain the bubble temperatures of twenty different non-ideal mixtures, the location of the azeotrope and the relation of the minimal reflux. The Wilson model was used for the activity coefficient and the cubic equation of state was used for the fugacity coefficient, utilizing the Pitzer correlation for the second virial coefficient.
