Q2) An air-NH3 mixture containing 20 mol % NH3 is treated with water in a packed tower to extract NH3. 1000 kg/h.m² is the gas flow rate. The temperature is 35 degrees Celsius, and there is one atmosphere of pressure. At 1.5 times the minimum water flow rate, 95 percent of NH3 is absorbed. If the entire height of the transfer unit is 1 m, how much taller does the = 0.746 x, tower have to be to absorb 95 percent of the NH3? According to Henry's law, ye where x and y are mole fraction units. Changes in gas flow rate are easy to overlook. The average molecular weight of the incoming gas combination is 26.472.
