Abstract: The present disclosure includes a system and method for the production of oxidized olefins. Two or more reactors include a number of reaction tubes each having a first surface defining a first side and a second surface defining a second of each of the tubes side are provided. A catalyst for catalytic oxidation of olefins can be located on the first side of the number of reaction tubes is included. A common supply line supplies inlets to each reactor that provide a mixture comprising olefins and oxygen to the catalyst. Product outlet streams of each reactor receive at least the oxidized olefin product and are joined to a single product stream. Coolant fluid passes through the reactors to remove heat from the number of reaction tubes and flows into a single coolant drum connected to the two or more reactors. The single coolant drum receives the coolant fluid from a number of coolant fluid outlet streams of each of the reactors.

Abstract: 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.
