A feed of 13,500 kgh consists of 8 wt% acetic acid (B) in water (A). The removal of the acetic acid is to be accomplished by liquid-liquid extraction at 25oC. The raffinate is to contain only 1 wt% acetic acid. The following four solvents, with accompanying distribution coefficients in mass-fraction units, are being considered. Water and each solvent (C) can be considered immiscible. For each solvent, estimate the kilograms required per hour if a single equilibrium stage isused.
