    摘要: Recovery of alcohol, in particular ethanol, by separating a vapor crude alcohol product obtained from the hydrogenation of acetic acid using a low energy process. The vapor crude ethanol product is separated in a column to produce a distillate stream comprising ethanol and at least one non-condensable gas. The vapor crude ethanol product may pass through a membrane before the first distillation column to separate the at least one non-condensable gas from the ethanol. The ethanol product is subsequently recovered from the distillate stream.

    摘要: In one embodiment, the invention is to a process for producing ethanol, the process comprising the steps of carbonylating methanol in a carbonylation system in the presence of a carbonylation catalyst under conditions effective to form acetic acid; hydrogenating the acetic acid in a hydrogenation system in the presence of a hydrogenation catalyst to form a crude ethanol product comprising ethanol and water; separating the ethanol from the water to form an ethanol stream and a water stream; and directing at least a portion of the water stream to the carbonylation system, e.g., for use as an extractant in a permanganate reducing compound removal system.
