Tutorial Solute A is to be recovered from a liquid mixture in a multi-stage countercurrent stripping tower. The liquid mixture enters the tower at a rate of 200 kgmol/h and contains 25 mol% of A. The gas enters the tower at rate 800 kgmol/h and is initially free of solute. If the exiting gas stream contains 5.0% A, Determine: a) The concentration of the exiting liquid stream and b) The number of equilibrium stages. The following figure represents the Y-X plot includes the equilibrium curve. Tutorial Solute A is to be recovered from a liquid mixture in a multi-stage countercurrent stripping tower.
