Problem 4 : A distillation column receives a feed that is $42 mole \% Benzene and 58 mole \% Toluene. The feed is$

Problem 4 : A distillation column receives a feed that is 42 mole \% Benzene and 58 mole \% Toluene. The feed is 25% saturated liquid. The column is at 1atm. A distillate that is 70 mole Benzene is desired. A total condenser is used. Reflux is a saturated liquid. The external reflux ratio is L0/D=1.5. Bottoms from the partial reboiler is 90 mole \% Toluene. a) draw q-line b) draw the operation line for the rectifying and stripping section c) Find the number of equilibrium stages and feed location if the overall tray efficiency is 1
