    摘要： A process for producing ethanol is disclosed, comprising the steps of hydrogenating acetic acid in a reactor in the presence of a catalyst to form a crude ethanol product, separating at least a portion of the crude ethanol product in a column into a first distillate comprising ethanol and a first residue comprising acetic acid and water, wherein a substantial portion of the water in the crude ethanol product that is fed to the column is removed in the first residue, and separating a portion of the ethanol mixture stream to the second distillation column to yield an ethanol product sidedraw, second residue comprising water and a second distillate comprising ethyl acetate. The water content of the ethanol product sidedraw may be further reduced to yield a stream having reduced water content.

    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.
