We have a distillation column with a partial condenser and a total reboiler separating a feed of 200 kmol/h. The feed is 40 mol % acetone and 60 mol % ethanol. The feed is a two-phase mixture that is 80% liquid. We desire a distillate vapor that is 85 mol % acetone and a bottoms that is5 mol% acetone. Column pressure is 1 atm. Reflux is returned as a saturated liquid and L/D = 3.25. Assume CMO. Equilibrium data is below.
