Countercurrent leaching of oil from meal. Acontinous countercurrent multistage system is to be used to leach oil from meal by benzene solvent (B3). The process is to treat 1000 kg/h of inert solid meal (B) containing 400 kg oil (A) and also 50 kg benzene (C). The inlet flow per hour of fresh solvent mixture contains 655 kg benzene and 20 kg oil. The leached solids are to contain 60 kg oil. Settling experiments similiar to those in the actual extractor show that the solution retained depends upon the concentration of oil in the solution. The data (B3) are tabulated below as N kg inert solid B/kg solution and yA kg oil A/kg solution. Calculate the amounts and concentration of the stream leaving the process and the number of stages required.
