In a packed absorber, the solute mole fractions in the gas at the inlet and outlet are 0.01 and 0.005, respectively, under base case conditions. The incoming solvent has no solute content in it. The absorber has 30 transfer units and is operating isothermally. It is desired that the outlet mole fraction of the solute be reduced to 0.002 by changing the tower pressure. How much should the tower pressure be changed in comparison to the base case? Assume that the liquid and gas flowrates at the inlet remains unchanged, the tower continues to operate isothermally at the same temperature as the base case. Also assume that it is a dilute system.

Question
In a packed absorber, the solute mole fractions in the gas at the inlet and outlet are
0.01 and 0.005, respectively, under base case conditions. The incoming solvent has
no solute content in it. The absorber has 30 transfer units and is operating
isothermally. It is desired that the outlet mole fraction of the solute be reduced to
0.002 by changing the tower pressure. How much should the tower pressure be
changed in comparison to the base case? Assume that the liquid and gas flowrates at
the inlet remains unchanged, the tower continues to operate isothermally at the same
temperature as the base case. Also assume that it is a dilute system.
