Adapted from Felder & Rousseau, pg. 308 Q6.97. 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 25°C are used as shown in the following diagram. 300 kg H2O/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. The total mass flow in the raffinate stream exiting unit 2 is 40 kg/h.
