Question
Q1 / Ammonia is to be removed from a 12 per cent ammonia-air mixture by countercurrent scrubbing with water in a packed tower at 293 K so that 98 per cent of the ammonia is removed when working at a total pressure of 101.3 kN/m2. If the gas rate is 0.065 kmole/m2s of tower cross-section and the liquid rate is 0.095 kmole/m2s, find the necessary height of the tower if the absorption coefficient KGa = 0.0015 kmol /m3s(KN/m2) partial pressure difference. The equilibrium data are: kmol NH/kmol water 0.02 0.03 0.04 0.05 0.08 0,11 0.16 Partial pressure NH: 1.5 2.5 3.5 4.5 6.5 9.0 14.0
