Absorption of Ammonia in Packed Tower. A gas stream 4.0 mol % NH3 and its ammonia content is reduced to 0.5 mol % in a packed absorption tower at 293 K and 1.013 x 105 Pa. The inlet pure water flow is 68 kg mol/h and the total inlet gas flow is 57.8 kg mol/h. The tower diameter is 0.747 m. The film mass-transfer coefficients are k’ya = 0.0739 kg mol/s.m3 mol frac and k’xa = 0.169 kg mol/s.m3 mol frac. Using the design methods for dilute gas mixtures, do as follows. (a) calculate the tower height using k’ya (b) calculate the tower height using K’ya
