(minimum liquid rate for absorption)! a packed tower is to be designed for the absorption of 98% of the ammonia(a) from an air-ammonia mixture containing 4% ammonia at a rate of 4200 nm (normal cubic metre) per hour using water as the solvent. the tower operates at 105.1 kpa and 303 k. the equilibrium data for nh3-water system at 303 k [sherwood, t. k., ind. eng. chem., 17(1925) 745] are given below: partial pressure of nh, (mm hg) 19.3 29.6 40.1 51.0 79.5 110 kg nh, per 100 kg water 3 4 5 7.5 10 (a) calculate and plot the equilibrium data as xa vs. pa, xa vs. ya and xa vs. ya . up to what value of pnh3 can the henry's law be used to describe the equilibrium? (b) calculate the minimum liquid rate for the absorption (the inlet water is nh3-free).
