NOVELTY - Preparing ethanol product using ethyl acetate, comprises adding ethyl acetate to a catalytic hydrogenation reaction unit and an ethanol refining unit, performing catalytic hydrogenation of ethyl acetate-hydrogen feed to ethyl acetate catalytic hydrogenation unit, to obtain reaction solution with ethanol, adding ethanol solution to hydrogenation reaction product, removing hydrogen from hydrogenation product, taking out nitrogen-ethane lightweight impurity component, removing acetaldehyde, ether and ethyl acetate impurity component, to obtain fuel ethanol production or absolute alcohol product.    USE - The method is useful for preparing ethanol product using ethyl acetate (claimed).    DETAILED DESCRIPTION - Preparing ethanol product using ethyl acetate, comprises adding ethyl acetate into a catalytic hydrogenation reaction unit and an ethanol refining unit, carrying out catalytic hydrogenation of ethyl acetate and hydrogen feed into ethyl acetate catalytic hydrogenation unit, to obtain a reaction solution-containing ethanol, adding ethanol solution to hydrogenation reaction product, to obtain ethanol, where ethanol refining unit includes a lightweight tower and a distillation column, and removing hydrogen from hydrogenation product in lightweight tower, taking out nitrogen and ethane lightweight impurity components, and treating hydrogenation product added into the rectification column, removing acetaldehyde, ether and ethyl acetate impurity components, to obtain fuel ethanol production or absolute alcohol products. An INDEPENDENT CLAIM is also included for ethanol production unit comprising purifying product distillation column provided with an ethanol tower wall, a separator located from the middle of the distillation column is divided into two parts, and there are two pre-formed wall column separation section main tower, and a lightweight tower is connected to the distillation column reactor which set with a pre-separation stage, and main distillation column overhead is used for recovery of enriched acetaldehyde and ether fractions, and main distillation column tower side draw the line side of ethyl acetate, water and ethanol ternary azeotrope fraction, and the main distillation column bottoms used for recovering fuel ethanol or absolute alcohol products.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the ethanol production unit (Drawing includes non-English language text).
