A distillation column with a total condenser and a partial reboiler is separating acetone from ethanol. The feed is 10.0 kgmoles/minute. Feed is 60.0 mole % acetone and is a saturated liquid. The distillate is 95.0 mole % acetone and leaves as a saturated liquid. The bottoms is 5.0 mole % acetone. Column pressure is 1.0 atmosphere. Reflux is returned as a saturated liquid. Column is adiabatic. External reflux ratio is L/D= 4.7. Assume CMO. Step off stages from top down. 1) Find the optimum feed stage and total number of equilibrium stages. (Step off stages from the top down). Calculate (L/D)min, and calculate Nmin at total reflux. Select a case study of altering the composition of acetone in the feed stream and show its effect on the number of stages xa 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.50 0.60 0.70 0.80 0.90 ya 0.262 0.348 0.417 0.478 0.524 0.566 0.605 0.674 0.739 0.802 0.865 0.929
