Q2: Solute A is to be removed from an inert gas B in a multi stage countercurrent absorption tower. The gas enters the tower at a rate 250 kgmole/h and contains 20 mol % A, the solvent enters the tower at a rate of 900 Kgmole/h and initially free of solute. Determine: " a- The concentration of the exiting gas stream. b- The number of stages, if the exit liquid stream contains 5 mol % A. The equilibrium relationship is YA= 3.75 XA
