Question 2: Water is used to extract acetone from a 30 wt.% acetone-70% Methyl isobutyl ketone (MIBK) mixture flowing at a rate of 200 kg/h. Two equilibrium stages at 25C are used as shown in the following diagram. 300 kg HO/h is fed to each extraction unit. The concentration of MIBK and acetone exiting the first extraction unit and feeding the second unit is 81 wt.% and 15 wt.%, respectively, with a total flow of 171 kg/h. The extract contains water, MIBK, and acetone. The concentration of water and acetone in the raffinate stream from unit 2 is 7% and 35%, respectively. a) Determine the composition of Extract 1 and Extract 2. b) Calculate the percentage of total acetone in the feed that would be removed. c) What would be the composition of the combined extract? Feed. 30% Acetone 70% MIBK 300 kg H0/h Extraction unit I 300 kg HO/h Extraction unit 2 Combined extract Raffinate
