LET’S TRY FOR THIS CALCULATION
Soy bean flakes containing 20% (w/w) oil was extracted through a single stage operation under atmospheric pressure with n-hexane as solvent. The clear liquid containing 15% (w/w) oil (solute) was discharged from the top layer and the precipitate leaving from the bottom contained 68% (w/w) solids. If the flow rate of feed was 2000 kg/h (F) and the stage operation was ideal, calculate the flow rate of solvent (S) and flow rate of overflow product (V). (10 marks)
