D6. A stripping column with an additional feed is separating two feeds containing acetone and ethanol. The column has a partial reboiler and no condenser. Feed 1 is 70.0 mol % acetone, has a feed rate F, = 200.0 kmol/h, and enters as a saturated liquid at the top of the stripping column. Feed 2 is 44.0 mol% acetone, has a flow rate F, = 100.0 kmol/h, is a two-phase mixture that is 40.0 mol% vapor, and enters the column at its optimum feed location. Boilup ratio V/B = 2, and bottoms is 26.0 mol% acetone. CMO is valid. Find a. Distillate and bottoms flow rates, Dand B, and distillate mole fraction of acetone Y dist b. Optimum feed location for feed F, and the total number of equilibrium stages required. 2
