Summary:In one embodiment, the invention is to a process for producing a water stream comprising the steps of hydrogenating acetic acid to form a crude ethanol product and separating at least a portion of the crude ethanol product in at least one column of a plurality of columns into a distillate comprising ethanol and a residue comprising the water stream. The water stream preferably is essentially free of organic impurities other than acetic acid and ethanol.
