A tray tower is to be desigend for absorption of SO2 from air by contact with fresh water. the entering gas has a mole fraction of SO2 of 0.1 and the exit gas must contain a mole fraction of SO2 no greater than 0.0005 the water flow rate uaed is to be 1.5 time the minimum and the inlet air flow rate is 500 kg/h the colum is to be operated at 1 atm and 303 K what is the water flow rate in Kmol/h for this operation we wish to determine the required stages for such water
Using the equation for the operating line of the absorption tower, we input the appropriate values so that the bottom of the tower is at equilibrium conditions:
