Ternary and Multispecies VLE

FIGURE 9.6 Measured activity coefficients at infinite dilution yf for a variety of solutions [1, p. 233-235], The systems corresponding to the legend are B, acetone in chloroform C, chloroform in acetone D, carbon disulfide in acetone E, acetone in carbon disulfide F, acetone in hexane G, hexane in acetone H, methyl ethyl ketone in ethyl benzene I, ethyl benzene in methyl ethyl ketone J, 1,4-dioxane in nitromethane K, nitromethane in l,4-dioxane L, 1,4-dioxaneinMA -dimethylfoniianiide M, A, A -dimethyl formamide in 1,4-dioxane N, diethyl ether in chloroform O, chloroform in diethyl ether P, water in ethanol and Q, ethanol in water. 

The general low-pressure VLE calculation procedure for mixtures with more than two species is the same as for two species we attempt to find equations for the fugacities in gas and liquid phases that present/] as a function of T, P, and the mol fractions in that phase. As the number of species goes up, the mathematical complexity increases and the intuitive
