    摘要: Embodiments of the present disclosure provide processes, columns, and systems for removing acetaldehyde from alkylene oxide in a feed stream and for providing an alkylene oxide-water stream that can be directly transferred to a glycol reaction process. The alkylene oxide purification column includes a first section to convert a feed stream into a gas phase portion and a liquid phase portion and a second section located in the column above the first section to separate alkylene oxide from the acetaldehyde, water, and other impurities that enter the second section from the first section.
