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 and water. Acetal byproduct can be reduced or removed through configurations of hydrolysis secondary reactors. The ethanol product is recovered from the residue stream.
