Question:

Consider the system water(1) + methylethylketone(MEK)(2) + acetic acid(AA)(3) at 299.85 K. For a ternary LLE system, estimate tie lines at x3α = 0.005, 0.01, 0.02, using UNIQUAC, where the parameter values are r = [0.92, 3.2479, 2.2024], q =[1.40, 2.876, 2.072], and the a values (in K ) are a12 = -2.0882, a21 = 345.53, a13 = 254.15, a31 = -301.02, a23 = -254.13, a32 = -4.5537. Let α be the water-rich phase. Plot the results on rectangular coordinates, using x1 as the abscissa and x3 as the ordinate. Connect the tie lines on the plot. Add the experimental tie lines (Table 14.3) to the same plot using different symbols.Table 14.3 Water (1) + Methylethylketone (MEK) (2) + Acetic Acid(3) System at T = 299.85 K a phase mol% 3
