1. A feed of 10,000 kg/h is 10 wt% acetic acid in water. The acetic acid will be removed using a solvent at 25 C. The raffinate will contain 1 wt% acetic acid. What solvent equilibrium ratio (also known as distribution coefficient), in mass fraction units, is required so that the solvent flow rate (kg/h) not exceed 5 times the feed? Assume that water and the solvent are immiscible.
