Abstract

Purifying and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol mixture are employed to allow recovery of ethanol and remove impurities. In particular, light ends are separated in an acetaldehyde removal column operating at a pressure greater than atmospheric pressure to recover acetaldehyde that may be returned to the reactor and reduce acetaldehyde concentrations in an ethyl acetate stream.
