摘要: Recovery of alcohol, in particular ethanol, from a crude product obtained from the hydrogenation of a feed stream comprising a carbonylation stock selected from the group consisting of acetic acid, and acetic acid and an ester thereof. The hydrogenation reaction produces a reactor product that is dehydrated to produce a dried product stream that comprises less water than the feed stream. This controls the additional water fed to the hydrogenation unit.

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 residue that comprises ethanol, acetic acid, and the extractive agent. The extractive agent may be water and may be separated from the residue and returned to the extractive distillation column.

摘要: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using a low energy process and an entrainer. The crude ethanol product is separated in an distillation column to produce a distillate stream comprising the entrainer. The ethanol product is recovered from the residue stream.
