摘要:
A method for separating monoethylene glycol (MEG) from one or more oxygenates. The method includes providing a stream comprising MEG and one or more oxygenates to a distillation column, providing a water feed stream to a bottom of the distillation column, and removing a recovery stream comprising MEG from the distillation column. The distillation column is operated at higher temperatures than the thermal stability of MEG and the one or more oxygenates.
