Liquid-liquid extraction is used to separate acetone and MIBK. A mixture of acetone and MIBK is fed to a mixing tank at a rate of 100 kg/min. Pure water is also fed to the tank and the mixture is allowed to settle (come to equilibrium) at room temperature (25°C). Two phases form upon settling. One phase has a flow rate of 125 kg/min and is rich in water (73% by mass). Use Figure to find the following values.
a. Calculate the flow rate and composition of the second phase.
b. Calculate the feed rate of water.
