Oil Extraction with Countercurrent Leaching: System. We need to design a multistage countercurrent leaching system to extract oil trom a solid mixture. Feed: The solid mixture were processing contains 28% oil, 60% component X, and 12% benzene. The feed rate is 2.5 tons per hour (tons/hr). Fresh Solvent: We'll introduce 1.25 tons/hr of fresh solvent containing 99.5% benzene and only 0.5% oil by weight into the last stage. Stage: In each stage, we assume 616.8 kg/hr of benzene is retained in the solid leaving. Desired Outcome: The final leftover solid exiting the last stage should only contain 1.5% oil. a.) Determine the minimum number of ideal stages required for this leaching process to achieve the desired outcome, b.) Calculate the percentage of oil in the solid leaving and liquid leaving from each stage.
