question 5

4. (20 pts) The process recovers composition A using multi-unit processes. Calculate the flow rate of F, D, E, H, J, K, and L streams. 5. (20 pts) A triple-effect evaporator aims to remove H2O in an incoming KCl aqueous stream from 25wt% to 3wt%. If the evaporator is producing 1.467104lbs per hour of KCl (with 3wt%H2O ), determine: (a) the feed rate of the KCl aqueous in lbs per hour. (b) the amount of H2O removed from the KCl aqueous in each evaporator
