Ex. 45: A soluble gas is absorbed from a dilute gas-air mixture

Ex. 45: A soluble gas is absorbed from a dilute gas-air mixture by countercurrent scrubbing with a solvent in a packed tower. The solvent liquor introduced to the column at the top contains no solute and it is desired to recover 90% of the solute by using 50% more iquid than the minimum necessary. What height of the packing will be required if the height of a transfer unit (HTU) of the proposed cower is 600 mm.
