| titleOfInvention | Alkylene oxide purification process |
| abstract | The invention relates to an alkylene oxide purification method, which mainly solves the problems of the prior art that the purity of an extracting agent is reduced, the loss is increased, the yield of alkylene oxide is reduced and the energy consumption is increased due to the accumulation of heavy component impurities. The process comprises the steps of separating a stream comprising alkylene oxide and extractant in a separation column having a first reboiler; it is characterized in that a material flow is extracted from the liquid phase of the tower plate of the separation tower and sent to an extractant purifier for treatment. The method can be used in the industrial production of alkylene oxide. |
