Immiscible Liquid-Liquid Extraction: A feed of 13,500 kg/hr consists of 8.0 wt% acetic acid in water. The removal of acetic acid is to be accomplished by liquid-liquid extraction in water at 25°C. The raffinate is to contain no more than 1.0 wt % acetic acid. SOLVENT K The following four solvents (and accompanying distribution coefficients are being considered. Water and each solvent can be considered immiscible. Methyl acetate Isopropyl ether Heptadecanol Chloroform 1.273 0.429 0.312 For each solvent, estimate the flow rate (kg/hr) if a single equilibrium stage is used to achieve the desired separation. 0.178 Discuss the solvent choices and indicate which may be the best option.
