    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.
