A tower, 15 cm in diameter, is to be used to lower the ammonia, NH3, concentration in a gas stream from 3.6 to 0.3 mol %. Water is fed to the top of the tower at a rate of 14.5 mol/s and the gas stream is fed to the bottom at a rate of 8 mol/s.

The tower operates isothermally at 293 K and 1.013×105 Pa. The overall mass-transfer capacity coefficient, KYa, may be assumed to equal 71 mol/m.s: ?YA. The equilibrium data at 293 K are as follows:
