| description | Embodiments of the present disclosure provide processes, columns, and systems for removing acetaldehyde from alkylene oxide in a feed stream (108) and for providing an alkylene oxide-water stream (120) that can be directly transferred to a glycol reaction process. The alkylene oxide purification column (100) includes a first section (102) to convert a feed stream into a gas phase portion (111) and a liquid phase portion (122) and a second section (104) located in the column above the first section (102) to separate alkylene oxide from the acetaldehyde, water, and other impurities that enter the second section (104) from the first section. |
