1. A three stage cross current extraction system is proposed to extract 1000 kg of aqueous solution containing 35 mass % trimethyl amine (TMA) and 65 % water using benzene as a solvent (98 % benzene and 2 % TMA). The amounts of solvent to be used in three successive stages are 815 kg, 950 kg and 2650 kg. Determine the fraction of solute removed if the stages are assumed to be ideal. (20 marks) 2.
