Solvent extraction and recovery of ethanol from aqueous solutions

Journal Article · · Ind. Eng. Chem. Res.; (United States)
OSTI ID:6829324

The distribution coefficients of ethanol and water from aqueous solutions to various organic solvents were measured, and separation factors were calculated. Several solvents had ethanol distribution coefficients greater than 0.1 and separation factors for ethanol/water greater than 10. The ethanol was stripped from selected solvents into a carrier gas and recovered by condensation. A conceptual processing scheme is proposed for separating and recovering ethanol from aqueous solutions by solvent extraction followed by gas stripping.
