absorption tower is use to remove SO2 from a mixture of SO2 and air. The flow rate and SO2 content of the gas mixture before the packed tower are 25 m3/min and 5.0 percent by volume, respectively. working pressure is 1 atm and temperature of the packed tower is 25 C. Removal of 90 percent of the SO2 is required, and water, initially pure, is to be used as the liquid solvent. The equilibrium line for SO2 and water can be estimated by y=30x. Determine the flow rate of water that represents 150 percent of the minimum liquid requirement, pressure drop, column diameter, and height of packing. By plotting equilibrium line.mass transfer coefficient to be 2.0x10-4 kmol/s.m2.atm
