taining 5 mol % NH3. The inlet gas and water rates are 1000 kg/hr.m² and 5000 kg/hr.m². The tower erates at 35°C and 1 atm. It is found that 90% of the incoming NH, is absorbed under these conditions. e equilibrium relation is given by y* = 0.746x. Kça = 62.4 kmol/hr.m³.atm Estimate the %-age increase in tower height in order to absorb 97% NH, if the operating conditions remain constant and variations in the flow rates due to higher absorption may be neglected. Discuss the additional informations required to determine the diameter of this packed tower.

A counter-current packed tower is to be used for water scrubbing of an air-NH3 mixture containing 5 mol% NH3. The inlet gas and water rates are 1000 kg/hr.m² and 5000 kg/hr.m². The tower operates at 35°C and 1 atm. It is found that 90% of the incoming NH, is absorbed under these conditions. The equilibrium relation is given by y* = 0.746x. Kaa = 62.4 kmol/hr.m³.atm (a) Estimate the %-age increase in tower height in order to absorb 97% NH, if the operating conditions remain constant and variations in the flow rates due to higher absorption may be neglected. Discuss the additional informations required to determine the diameter of this packed tower. (b)
