![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]
