You have a saturated liquid feed consisting of 100 moles/hour of a mixture of NH3, CaCl2, and H2O, with the following composition: NH3 (mole fraction 0.20), CaCl2 (0.40), and H2O (0.40). You want to fractionate this mixture in a distillation column operating at a pressure of 101.3 kPa abs. Your goal is to recover 90% of the NH3 in the distillate and 90% of the CaCl2 in the bottoms. What would be the composition of the distillate and bottoms, and what would be the flow rate of each stream? a) The temperature of the feed b) The composition of the vapor that would be in equilibrium with this feed c) The moles per hour and the composition of the distillate and the bottoms d) The temperature at the top (dew point) and the bottom (bubble point) of the tower

e) Solve the equlibirum vapor curve using Raoult's and Dalton's Law

f) Calculate the minimum number of stages required to carry out the separation, use Fenske's Equation.

g) The reflux ration at which the column operates in order to achieve the required separation use Erbar Maddox Chart and Underwood Equation. It would be nice if you can do this calculation on an excel, if not type it out.
