A packed column (50 cm diameter) is to be used to remove 6 mole percent of ammonia gas from air mixture at 1 atm. The inlet gas flow rate is (1200 + (student number/10)) kg/min. m; the recovery of the separation process is 97% ammonia and the overall gas transfer coefficient is 2.134 kg/hr. m’ atm. The equilibrium relation for the system may be taken as Y = 1.15€ X, where x and y are expressed in mole fraction. Note:- convert the composition to the molar ratio Determine:

1. minimum mass liquid flow rate
2. The number of transfer unit and packed column volume that will be required for designing the column using 1.25 of minimum liquid flow rate.
