| titleOfInvention | Heat-integrated high pressure system for separation of byproducts from an olefin stream |
| abstract | The present invention is a heat-integrated process for obtaining an ethylene and propylene enriched stream from an oxygenate to olefin reactor. The process comprises providing an effluent stream from an oxygenate to olefins reactor. The effluent stream comprises ethylene, propylene and one or more byproducts selected from the group consisting of propane, methyl acetylene, propadiene, dimethyl ether, acetaldyhyde and butylene. The process further includes quenching the effluent stream with the quench medium to provide an olefin stream. The olefin stream is separated into a heavy fraction and a remaining fraction. The remaining fraction is directed to a distillation column which separates the remaining fraction into a first fraction comprising a majority of both ethylene and a propylene and a second fraction comprising at least a majority of one or more heavier fraction. The bottoms of the distillation column is reboiled by the quench medium. The separation step allows the bottoms of the distillation column to be reboiled at a lower temperature. |
