2. A packed tower is to be designed to remove 85% of the ammonia (NH3) from a gaseous mixture of 9% ammonia and 91% air, by volume. Molar flow rate of the inlet gaseous mixture is 100 mol/hr. The equilibrium and operating line for this water-ammonia are given below. X and Y values are molar ratios in liquid and gaseous phase, respectively. 0,50 0,45 0,40 0,35 0,30 Equitibrium Line > 0,25 0,20 Operating Line 0,15 0,10 0,05 0,00 0,000 0,002 0,004 0,006 0,008 0,010 0,012 0,014 0,016
