1) Solubility and conjugate layer data for the isoamyl alcohol-ethyl alcohol-water system were used as a model for illustrating the principles of fusel oil separation and decantation. Curves for fusel oil and ethyl alcohol concentrations in both oil and water phases and percentage of fusel oil recovery as a function of water dilution ratios were presented for three mixtures. The results indicate that dilution ratios of 2 to 2.7 would improve fusel oil recovery by decantation.
2) Some practical recommendations for fusel oil decanter connections and operations were made.
