A distillation column with a partial reboiler and a total condenser is being used to separate a mixture of Comp A (1), Comp B (2), and Comp C (3). The feed is 40.0% molc Comp A. 30.0% mole Comp B and 30.0% mole Comp C. The feed is input as a saturated vapor. We desire 96.50% recovery of the Comp B in the bottoms and 99.50% recovery of the Comp A in the distillate. The reflux is returned as a saturated liquid, and CMO can be assumed. Equilibrium can be represented as constant relative volatilities. Choosing Comp B (2) as the reference component, a12 = 1.40 and a32 = 0.80. Use a basis of 100 moles of feed/h. Find the number of equilibrium stages required at total reflux.

QUESTION 19 A distillation column with a partial reboiler and a total condenser is being used to separate a mixture of Comp A (1), Comp B (2), and Comp C (3). The feed is 40.0% molc Comp A. 30.0% mole Comp B and 30.0% mole Comp C. The feed is input as a saturated vapor. We desire 96.50% recovery of the Comp B in the bottoms and 99.50% recovery of the Comp A in the distillate. The reflux is returned as a saturated liquid, and CMO can be assumed. Equilibrium can be represented as constant relative volatilities. Choosing Comp B (2) as the reference component, a12 = 1.40 and a32 = 0.80. Use a basis of 100 moles of feed/h. Find the number of equilibrium stages required at total reflux.
