Ammonia is to be removed from a 10 per cent ammonia-air mixture by countercurrent scrubbing with water in a packed tower at 293 K so that 99 per cent of the ammonia is removed when working at a total pressure of 101.3 kN/m². If the gas rate is 0.95 kg/m²s 155 of tower cross-section and the liquid rate is 0.65 kg/m²s, what is the necessary height of the tower if the absorption coefficient KGa difference. The equilibrium data are: = 0.001 kmol/m's (kN/m²) partial pressure
