Using a packed column, ammonia is absorbed from air to water. The incoming gas contains 6% NH3 and its flow rate is 200 kmol / hour. The exiting gas contains 0.2% NH3. Pure water is fed to the column as liquid at a flow of 230 kmol / hour. Gas phase bulk transfer unit height is known as HOG = 1.7 m and the equilibrium relation can be taken as y = 0.9x under these operating conditions. a) Calculate the column fill height. b) Find the ratio of L '/ Lmin used.
