A system and method for the production of oxidized olefins. The system includes two or more reactors having a number of reaction tubes. A catalyst for catalytic oxidation of olefins is on a first side of the number of reaction tubes. A common supply line supplies a mixture comprising olefins and oxygen to the catalyst. Product outlet streams from each reactor are joined to a single product stream. Coolant fluid passing through the reactors flows into a single coolant drum. The single coolant drum supplies the coolant fluid at a common temperature to a number of coolant fluid inlet streams of each reactor.

Production of oxidized olefins

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.

Alkylene oxide purification systems

Embodiments of the present disclosure include processes and systems for recovering alkylene oxide. System embodiments include a stripping section located in an alkylene oxide recovery column to convert a feed stream comprising to a first gas phase portion comprising alkylene oxide, a condensing zone comprising at least a first condenser and a second condenser configured in series, and a reabsorption region located in the alkylene oxide recovery column above the last of the at least two condensers.

Alkylene oxide recovery systems

The invention relates to improved systems for recovery of alkylene oxide from feed streams containing the same in an alkylene oxide recovery column. The invention also relates to improved processes for recovery of alkylene oxide from feed streams containing the same in an alkylene oxide recovery column.
