A 5% (by weight) solution of acetaldehyde in toluene is extracted with water in a three stage cross-current unit. If 100 kg of water is used per stage for 500 kg of feed, calculate (using graphical method) the percentage extraction of acetaldehyde and the weights of final raffinate and mixed extract. The equilibrium relationship is given by the equation, Y = 2.3 X where Y kg acetaldehyde/kg water and X = kg acetaldehyde/kg toluene. Assume that toluene and water are immiscible with each other. =
