Question 3 1. Sunflower oil is leached from seeds with hexane in mixer-settler leaching extractor. If 100 kg seeds with 20 wt% oil is leached with 100 kg of fresh hexane solvent. The value of N (solid to solution ratio) for the slurry underflow = 1 kg insoluble solid/kg solution retained. a) Calculate the amounts overflow and the underflow slurry leaving the extractor. (3 marks) b) Calculate the compositions of the overflow and the underflow slurry leaving the extractor
