Question
Use theMcCabe–Thiele method to compute, at 1 atmnumber of equilibrium stages N, for R/Rmin = 1:3,and the optimal feed-stage location for benzene distillate and bottoms purities of 99.9 and 0.1 mol%, respectively, using a reflux ratio of 1.88, which is about 30% higher than the minimum reflux of 1.44.At the top of the column, α = 2.52; at the bottom, α = 2.26.
