In a solid-liquid extraction process operated according to the principle of continuous counter current the oil of a food will be extracted with pure hexane. As long as 7200 kg of inert solids, 1200 kg of oil per hour and Mixture containing 400 kg of hexane enters. The upstream leaving the total stage, by weight It contains 60% hexane and 40% oil. A total of 85% of the oil in the inlet stream will be recovered. Lower the flow is constant in N = 2.0 kg inert solid/kg solution. According to this, a) The amount and composition of the output streams, b) Find the theoretical number of steps required to perform the extraction.
