The purge gases from a synthetic ammonia plant contain 4% ammonia by volume and 96% hydrogen, nitrogen, argon and other inerts. This gas is to be scrubbed at 5 atmosphere pressure with water in a bubble plate tower maintained at 68°F by cooling coils. With water and inert gas rates of 0.88 and 4 lb/min ft2 of tower cross section respectively, how many theoretical plates will be required to produce a solution containing 13% ammonia by weight? The average molecular weight of the inert gas is 21. Data: the following gives the equilibrium partial pressure of ammonia solutions at 68°F 69.6 166 5 10 Partial pressure, torr 12 Pound NH3/100 gram H2O 1 19.2 31.7 1.5 5 50 3.75

Q1: A rotary countercurrent dryer is fed with ammonium nitrate containing 5% moisture at the rate of 1.5 kg/s, and discharges the nitrate with 0.2% moisture. The air enters at 405 K and leaves at 355 K; the humidity of the entering air being 0.007 kg moisture/kg dry air. The nitrate enters at 294 K and leaves at 339 K. Neglecting radiation losses, calculate the mass of dry air passing through the dryer and the humidity of the air leaving the dryer. Latent heat of water at 294 K = 2450 kJ/kg. Specific heat capacity of ammonium nitrate = 1.88 kJ/kg K. Specific heat capacity of dry air = 0.99 kJ/kg K. Specific heat capacity of water vapor = 2.01 kJ/kg K.
