摘要： A crude ethanol product obtained from the hydrogenation of acetic acid comprises ethanol and ethyl acetate. Using a distillation column operated at a pressure of from 0.1 to 100 kPa, the ethyl acetate and ethanol may be effectively separated. In addition, maintaining the amount of water that is fed to the distillation column to an amount less than 10 wt. %, based on the weight of all components fed to the distillation column, provides an energy benefit.

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 acetaldehyde and a residue stream comprising ethanol, acetic acid, ethyl acetate and water. The ethanol product is recovered from the residue stream.

摘要： Recovery of an alcohol such as ethanol from a crude alcohol product, preferably 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 in a second column as an ethanol side stream.

摘要： A process for operating a distillation column to separate an ethanol mixture comprising ethanol and acetic acid where the recovered ethanol comprises less than 700 wppm acetic acid. The operating conditions for the column may vary depending on the fed composition. In particular the process provides energy efficient recovery of ethanol with low concentration acetic acid.
