摘要：
The present invention is directed to processes for recovering ethanol obtained from the hydrogenation of acetic acid. Acetic acid is hydrogenated in the presence of a catalyst in a hydrogenation reactor to form a crude ethanol product. The crude ethanol product is separated in one or more columns to recover ethanol. In some embodiments, less than 10 wt. % ethanol is recycled to the hydrogenation reactor.
