question 4

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. 4. (20 pts) The process recovers composition A using multi-unit processes.
