A fermentation beer of 450 L h -1 containing 2600 μg L -1 of an antibiotic like streptomycin is to be extracted with amyl acetate of 43 L h -1 . 90% of the antibiotic is extracted. The partition coefficient is given as 57. Determine the Number of stages required. After extraction, the antibiotic is to be stripped back to aqueous phase. 43l/h of streptomycin extract is to be stripped with water. As a result, K is now 0.11. We want to use 3 stages and have 95% recovery. How much water should we use?
