Extraction of oil using hexane. Orange peels, containing 20% oil, 30% water, and 50% insoluble matter, are extracted by contacting with fresh organic solvent hexane. Hexane and water are assumed immiscible. 90% of the oil is recovered in the solution (extract) containing 50% by mass of oil. The raffinate containing the unextracted oil has a mass of

Extraction of oil using hexane. Orange peels, containing 20% oil, 30% water, and 50% insoluble matter, are extracted by contacting with fresh organic solvent hexane. Hexane and water are assumed immiscible. 90% of the oil is recovered in the solution (extract) containing 50% by mass of oil. The raffinate containing the unextracted oil has a mass of 55 kg. Calculate a. mass of orange peel that was processed (kg) b. mass of fresh hexane used (kg) c. concentration of oil in the raffinate stream (mass percent)
