Question:

For the systems specified below, obtain residue curve maps and plot the range of possible distillate and bottoms compositions for the given feeds. UNIQUAC parameters are provided.

(a) methanol(1) + ethanol(2) + ethyl acetate(3), z1 = 0.25, z2 = 0.25, z3 = 0.5, r = [1.4311, 2.1055, 3.4786], q = [1.432, 1.972, 3.116], a parameters (in K); a12 = 91.226, a21 = 124.485, a13 = 74.2746, a31 = 389.285, a23 = 31.5531, a32 = 183.154.0

Aspen 2006 gives poor VLE using LLE parameters for this system. Use the provided parameters.

(b) Solve part (a), but use z1 = 0.4, z2 = 0.4, z3 = 0.2.

(c) methanol(1) + 2-propanol(2) + water(3), z1 = 0.2, z2 = 0.6, z3 = 0.2, r = [1.4311, 2.7791, 0.92], q = [1.432, 2.508, 1.4], a parameters (in K); a12 = 39.717, a21 = 26.6935, a13 = 112.697, a31 = 176.077, a23 = 151.061, a32 = 55.1272.

(d) Solve part (c), but use z1 = 0.6, z2 = 0.2, z3 = 0.2.

(e) methanol(1) + ethanol(2) + benzene(3), z1 = 0.25, z2 = 0.25, z3 = 0.5, r =­ [1.4311, 2.1055, 3.1878], q =­ [1.432, 1.972, 2.4], a parameters (in K); a12 = 91.2264, a21 = 124.485, a13 = 27.2253, a31 = 559.486, a23 = 42.6567, a32 = 337.739.

(f) Solve part (e), but use z1 = 0.4, z2 = 0.4, z3 = 0.2.
