Ammonia is absorbed from air stream using water at 0 °c and 1.30 atm. the entering water stream is pure water. the entering vapor is 18 mol% ammonia. the goal is to recover 82% of the ammonia in the water outlet stream. the inlet gas flow rate is 50 kmol/hr. absorbent flow rate is 1.5 times the minimum solvent rate. equilibrium data are given below. assume dalton’s law applies. 1st column ‘g nh3/1g h2o’: 0.05 | 0.075 | 0.100 | 0.15 | 0.20 | 0.25 | 0.30 | 0.40 | 0.50 | 0.60 |‘partial pressure of nh3, mmhg’: 11.2 | 17.7 | 25.1 | 42.7 | 64 | 89.5 | 119 | 190 | 275 | 380
