A mixture of 25 % ammonia gas and 75 % air ( dry basis ) is passed upward through a vertical scrubbing tower, to the top of which water is pumped. scrubbed gas containing 0.5 % ammonia leaves the top of the tower. , and an aqueous solution containing 10 % ammonia by weight leaves the bottom. both entering and leaving gas streams are saturated with water vapor. the gas enters the tower at 100 OF and leaves at 70 oF . The ammonia mixture enters the tower enters the tower at a rate of 1000 ft3/min measured as dry gas at 60 ^oF and 1 atm. the pressure of both streams and throughout the tower = 15 lbf /in2 g. what percentage of the ammonia entering the tower is not absorbed by water , how many gallons of water per minute are pumped to the top of the tower.
