Stripping #1: Ammonia from Water Ammonia is stripped from a dilute aqueous solution by countercurrent contact with air in a column containing seven sieve trays. Under specific conditions the equilibrium relationship is ye = 0.75 xe, and when the molar flow of air is 1.8 times that of the solution, 90% of the ammonia is removed. (a) How many ideal stages does the column have and what is the stage efficiency? (b) Under what thermodynamic conditions (temperature, pressure) is the column operating? [Discuss]
