摘要：
Recovery of an ester feed stream, optionally with the recovery of ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of the crude ethanol products are employed to allow recovery of the ester feed stream and for integration of the ester feed stream with an esters production process. The composition of the ester feed stream may vary, but at least comprises ethyl acetate and ethanol. The ester feed stream may be fed to one or more locations within the esters production process depending on the composition of the ester feed stream.
