摘要:
Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using an extractive distillation column. The column yields a residue that comprises ethanol, acetic acid, and the extractive agent. The extractive agent may be water and may be separated from the residue and returned to the extractive distillation column.
