[#400] Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m 2 and the solvent flow, rate is 400 moles of S/m 2 .hr. The equilibrium data is represented by Y = 3X 2 , where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is
