摘要：

The flash process for the removal of ethanol from commercial oleic acid has been experimentally studied and modelled using a modified Redlich-Kwong-Soave equation of state (RKAES) and the ASPEN process simulator. Using feed ethanol and water concentrations spanning the range of expected liquid-liquid extraction concentrations, it was found that 93.6% by weight of ethanol in the distillate was obtained consuming only 2 MJoules of energy per kilogram of ethanol recovered. The RKAES model was found to reasonably predict the ethanol recovery and purity with errors under 5%. Commercial oleic acid was found to be completely non-inhibitory towards the growth of Saccharomyces cerevisiae cells when used for in-situ extraction at a concentration of 50% of the total fermenter volume.
