A distillation column is separating a feed that is 20 mol% methanol, 50 mol% n-propanol, and 30 mol% n butanol. Feed is 750 kmol/h. We wish a 92 mol% recovery of methanol in the distillate and 95% recovery of n-propanol in the bottoms. Use L/D=7.0. Feed is a saturated liquid. The column has a partial reboiler and a total condenser. You may assume that n-butanol does not distribute (all butanol exits in the bottoms). Relative volatilities with respect to n-propanol are: methanol=3.58, n-propanol=1.0, n-butanol=0.412. Relative volatilities may be assumed to be constant. a) Find D, B, xi,dist, xi,bot b) Step off stages using second stage above the partial reboiler (the third equilibrium contact from bottom) for feed location and find the total number of stages and the calculated distillate mole fractions.
