90% of Ammonia is stripped from a 5 mole% dilute aqueous solution by countercurrent contact with pure (ammonia free) air. The equilibrium relationship is y=0.8x. The molar flow rate of air is 1.5 times that of the ammonia solution. This process is carried out in a real column with 10 plates. The process is operated at a total pressure of 101.3 kPa. a. Draw a process diagram and show all flow streams with the corresponding compositions. b. Draw the equilibrium and operating lines. c. Using the absorption factor method, calculate the number of ideal stages in this absorption column. What is the real column's efficiency? d. Using the Kremser equation, calculate the number of ideal stages in this absorption column. 90% of Ammonia is stripped from a 5 mole% dilute aqueous solution by countercurrent contact with pure (ammonia free) air.
