In a solid - liquid extraction process operated according to the principle of continuous reverse current, the oil of a nutrient will be extracted with pure hexane. A mixture containing 7000 kg of inert solid, 1500 kg of oil and 500 kg of hexane enters the process per hour. The upper stream leaving the total stage contains 65% hexane and 35% oil by weight. A total of 85% of the oil in the inlet current will be recovered. The underflow is constant at N=2.0 kg inert solid/kg solution; a. Find the amount and composition of the output current b) Find the theoretical number of steps required to perform the extraction
