Abstract:
The present invention relates to processes for the recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising ethyl acetate, ethanol and acetaldehyde and a residue stream comprising ethanol, acetic acid and water. The ethanol product is recovered from the residue stream. A liquid recycle stream is sent to a second vaporizer to form a second vapor feed stream that is fed to the hydrogenation reactor.
