Title:

METHOD AND SYSTEM FOR PRODUCING EPOXYALKANE

Document Type and Number:

WIPO Patent Application WO/2019/105453

Kind Code:

A1

Abstract:

Disclosed are a method and system for producing an epoxyalkane, the method and system mainly solving the problems in the prior art of the accumulation of heavy fraction impurities resulting in a decrease in the purity of an extracting agent, an increase in loss, a decrease in the yield of an epoxyalkane and an increase in energy consumption. The method comprises the step of separating a stream containing an epoxyalkane and an extracting agent in a separation tower with a tower kettle reboiler, and is characterized in that part of a stream in the tower kettle of the separation tower enters an extracting agent purifier and is treated to obtain a gas phase light fraction that returns to the separation tower and a liquid phase heavy fraction that is subjected to a post-treatment. The method can be used in the industrial production of an epoxyalkane.
