A distillation column with a total condenser is separating a feed that is 30 mol% acetone from ethanol. Distillate Xp = 0.9 and bottoms XB = 0.13 (both for Acetone). L/V = 0.8 and V/B = 1.0. (a) Find the composition of the liquid leaving the 5th stage below the total condenser. (b)The column has a partial reboiler that acts as an equilibrium contact. Find the vapor composition leaving the 2nd stage above the partial reboiler. (c)Find the optimum feed location, total number of stages and required q value of feed.
