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.

摘要： Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using an extractive distillation column. The column yields a first residue that comprises ethanol, ethyl acetate, acetic acid, and water. The first residue is separated in a second column to yield a second distillate comprising ethanol and ethyl acetate. The second distillate is then separated in a third column to yield a third distillate comprising ethyl acetate and a third residue comprising ethanol.
