摘要: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid and by reacting a portion of the crude ethanol product or one or more derivative streams containing ethyl acetate obtained therefrom in the presence of hydrogen, via hydrogenolysis. The one or more derivative streams comprise ethyl acetate that are reacted in via hydrogenolysis form additional ethanol that may be directly or indirectly fed to the separation zone or the hydrogenation reactor.

摘要: To reduce acetal concentrations when separating ethanol from a crude product in one or more distillation column, at least one of the columns is operated at a higher pressure to increase the equilibrium constant that favors hydrolysis of the acetal. The crude product may comprise ethanol, acetaldehyde, water and one or more acetals, such as diethyl acetal. The acetal concentration may be reduced thus reducing the need to separate acetal from the crude product.
摘要翻译: 为了减少在一个或多个蒸馏塔中从粗产物中分离乙醇时的乙缩醛浓度,至少一个塔在较高的压力下运行以增加有利于缩醛水解的平衡常数。 粗产物可以包括乙醇,乙醛,水和一种或多种缩醛,例如二乙缩醛。 缩醛浓度可能会降低,从而减少了从粗产物分离乙缩醛的需要。

摘要: Recovery of alcohols, in particular ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid using a reduced energy process. The crude ethanol product may be fed to a distillation column in which a substantial portion of the water is removed with the acetic acid in the residue. The ethanol product is obtained from the distillate.

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.
