摘要：
A process for recovering ethanol obtained from the hydrogenation of acetic acid. The crude ethanol product is separated in a column to produce a distillate stream comprising acetaldehyde and ethyl acetate and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. Unreacted acetic acid can be reduced or removed through configurations of esterification secondary reactors. The ethanol product is recovered from the residue stream.
