A distillation column with full condenser and partial reboiler separates acetone from isopropanol. The molar flow rate of the charge is 10 kmol/min with 50 mol% saturated liquid acetone. The distillate must have 95 mole % saturated liquid acetone, the residue contains 5 mole % acetone. Operating pressure is 1 atm. the reflux returns as a saturated liquid and the reflux ratio is 4.7. Determine the optimal charge stage, the number of equilibrium stages, the minimum number of equilibrium stages, and the minimum reflux ratio. Balance data in the attached table.
