mass transfer

An absorption tower is packed with 1-in ceramic Rashing rings. It is to be designed to treat 2500 ft3/h of air contains 2% NH3 at 1 atm and 20 C. Pure water is to be used as a solvent. The ratio of the air flow to liquid flow is 1 lb of air per lb of liquid. If the gas velocity is to be one-half the flooding velocity what should be the diameter of the tower. Packing factor F = 179 ft2/ft3) L = 62.3 lb/ft3, L = 1 cP
