Oilseeds containing 20% oil by weight will be extracted with pure solvent in a multi-stage leaching system. In the extract phase (overflow, V₁) containing 50% oil by weight, 90% of the oil in the feed will be recovered. Since it is known that 2 kg of inert solid is carried per 1 kg of solution in the underflow (LN), for this solid- liquid extraction process calculate and draw graph (if necessary); a) Extract phase (overflow) flow rate b) Underflow flow rate and composition c) The flow rate of solvent used d) Number of theoretical plates e) Percentage of non-recovered oil.
