摘要： The application relates to a process for recovery of alkylene oxide comprising: Introducing a feed stream containing alkylene oxide to a stripping section of an alkylene oxide recovery column; stripping alkylene oxide from the feed stream to form a first gaseous portion, wherein the first gaseous portion flows from the stripping section to the reabsorption région of the alkylene oxide recovery column, and wherein the reabsorption région further comprises a first reabsorption section and a second reabsorption section; partially condensing the first gaseous portion into a liquid reflux stream and an alkylene oxide rich vapor stream, wherein the liquid reflux stream is in physical communication with the stripping section; reabsorbing a first fraction of the alkylene oxide rich vapor stream in a first water stream and reabsorbing a second fraction of the alkylene oxide rich vapor stream in a second water stream to form a second agueous solution in the second reabsorption section.

摘要： The present disclosure includes a system and method for the pro¬ duction 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 com¬ mon 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 re¬ actors 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. The single coolant drum supplies the coolant fluid at a common temperature to a num¬ ber of coolant fluid inlet streams of each reactor.
