Isothermal and isobaric VLE were cak-ulated from the isoplethic results with a extended UNIQUAC equation and these date agree well with the literature data.展开更多

The equilibrium composition of the vapor phase was calculated from pTx by indirect method. The model parameters of the liquid activity coefficient of the Wilson, NRTL, Margules and van Laar equations was corrected by the least square method. The ternary system VLE data were predicted by the Wilson equation, with the calculated boiling points showing good agreement with the experimental data.展开更多
