Solute A is to be absorbed from a binary mixture containing 7.5% of A with solvent B in a packed tower. Based on flooding calculation, a tower diameter of 1.2 m is selected. Total rate is 60 kmol/h. The exit gas must not contain 0.2% of solute A. Solute free liquid B enters from the top of the tower at 40 kmol/h. The gas phase and liquid phase mass transfer coefficients based on mole ratio unit are: kx=2.05 kmol/mh and ky =1.75 kmol/mh. The equilibrium line Equation is Y=0.63X. Specific interfacial area of gas-liquid contact is 71 m/m

(a) Calculate packing height required for the desired separation.

(b) For 99.5% solute A removal, what % increase in packed height is needed?

(c) Determine slopes of operating line in each case.
