separation process

9) A water ethanol mixture at the rate of 100 kmol/h containing 30 mol% ethanol is subjected to a distillation column (with partial reboiler and total condenser) to be separated into a top product containing 75 mol% ethanol and a bottom product containing 5 mol% ethanol. The feed is a saturated liquid. The reflux ratio is 2. The equilibrium curve based on the mole fraction of more volatile component (ethanol) is given.

a) Determine the rates (kmol/h) of top and bottom products.

b) Find the number of theoretical (ideal) plates.

c) Find the feed plate.
