$CHEMICAL ENGINEERING SEPARATION PROCESSES A saturated liquid mixture containing mol fraction$

CHEMICAL ENGINEERING SEPARATION PROCESSES A saturated liquid mixture containing mol fraction %42A is sent to a distillation column at a rate of 500mol/hr. The overhead product contains mol fraction %90A and the bottom product contains mol fraction \%92 B. The reflux ratio is 1.5 and total condenser is used in the system. Equilibrium Data (Mol Fraction A) Enthalpy-concentration data NB: the commas on values represent decimal points a) Find the ideal number of stages using the Ponchon-Savarit method. At what stage is the feeding? b) If the cooling water enters the condenser at 20C and leaves at 70C, find out the amount of cooling water used. (Cpr1cal/gC) c) If saturated water vapor at 120C is used as a heater in the boiler, find the required amount of water vapor in 1 hour ( 1sb505cal/g)
