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

摘要： Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol product are employed to allow recovery of ethanol and remove impurities. In addition, the process involves separating the crude ethanol product using an extractive distillation column that employs an extraction agent, such as a recycled stream comprising water.

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： A process for producing ethanol comprising the steps of hydrogenating an acetic acid feed stream to form a crude ethanol product and separating at least a portion of the crude ethanol product to form an ethanol stream and at least one vent stream. The vent stream comprises non-condensable gases at least one volatile organic. The process further comprises the step of scrubbing the vent stream with at least two different solvents to recover the volatile organics. The vent stream may also comprise entrained ethanol, which may also be recovered.
