Zusammenfassung:Purification and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of a crude ethanol mixture are employed to allow recovery of ethanol and remove impurities. In particular, the process involves one or more sidedraws to regulate C3+ alcohols concentration in the recovered ethanol.
