A mixture of acetone and ethanol is to be separated in a distillation column operating at 1 atm with a total condenser and a partial reboiler. The distillate is 90 mol% acetone and the bottoms is 10 mol% acetone. The reflux is returned as a saturated liquid. The boilup ratio is 2.0. Two feed streams are fed to the column. The first feed has a flow rate of 75 kmol/h and is a saturated liquid with a composition of 60 mol% acetone. The second feed has a flow rate of 100 kmol/h with a composition of 40 mol% acetone and is a vapor-liquid mixture that is 60% vapor. Assume CMO and use the acetone-ethanol x vs. y diagram. Find D and B, plot the two feed lines and three operating lines on the x vs. y diagram and find the optimum feed location for the two feed streams along with the total number of equilibrium stages required to achieve the desired separation.
