PROBLEM 2 Acetone in a mixture containing 20mol% of acetone is to be extracted by n-heptanone. It is required that the acetone concentration of the raffinate is reduced to 1 mol%. The phase-envelope and some tie-lines are shown below a. What is the number of moles of n-heptanone required per mole of feed if a single stage extraction is used? b. What is the minimum number of moles of nheptanone required per mole of feed if a single stage extraction is used? c. If we want to produce an extract contain 40% of acetone, number of moles of n-heptanone required per mole of feed? d. How many stages are required in part (c)? e.
