摘要： The invention is to a process for removing contaminants from a compressor and/or compressor intercooler in a methanol to olefin separation system. The process comprises compressing an effluent in a compressor having an inlet and an outlet and a compressor surface, the compressing occurring under conditions effective to form a contaminant on the compressor surface. A contaminant-removal medium is injected into the compressor or intercooler and the contaminant-removal medium contacts the contaminant under conditions effective to remove the contaminant from the compressor or intercooler inner surface thereby forming a mobile contaminant. The mobile contaminant is then removed from the compressor or intercooler.

摘要： This invention comprises a method of producing ethylene rich product streams from a pressurized charge gas mixture of olefins and other components received from olefin generation/preparation processes. The method of this invention may eliminate the need for cryogenic fractional distillation and other special separation equipment operating at temperatures below -55.degree. F., and thus also potentially eliminate the refrigeration and heat exchange equipment needed to achieve those low temperatures. Alternatively, the method of this invention may eliminate the need for a circulating lean oil absorbant material, and thus also potentially eliminate the heat exchange equipment and reduces the refrigeration and fractional distillation load required to manage that material. In accordance with the process of this invention, a secondary ethylene rich product stream is produced at a rate and composition suitable for subsequent generation of a primary ethylene rich product potentially containing substantially no components having a boiling point at least as low as ethylene. Further, the secondary ethylene rich product stream may be suitable as feedstock in the production of ethylene derivatives, or be amenable to further concentration of ethylene using bulk separation techniques, or combinations thereof. Accordingly, the capital and operating cost associated with the manufacture of ethylene rich product streams from pressurized charge gas mixtures made by olefin generation processes may be significantly reduced through the method of this invention.
摘要翻译：本发明包括从烯烃生产/制备过程接收的烯烃和其它组分的加压充气混合物生产富含乙烯的产物流的方法。本发明的方法可以消除对在低于-55°F的温度下操作的低温分馏和其它特殊分离设备的需要，从而也可能消除实现这些低温所需的制冷和热交换设备。或者，本发明的方法可以消除对循环贫油吸收材料的需要，从而也可能消除热交换设备并降低管理该材料所需的制冷和分馏负荷。根据本发明的方法，以适合于随后产生可能基本上不含有至少与乙烯一样低的沸点的组分的初级富乙烯产品的速率和组成来生产次级富乙烯产物流。此外，次级富乙烯产物流可以适合作为生产乙烯衍生物的原料，或适于使用本体分离技术或其组合进一步浓缩乙烯。因此，通过本发明的方法可以显着地减少与通过烯烃生成方法制备的加压充气气体混合物制造富含乙烯的产物流相关联的资本和运营成本。

摘要： The present invention is directed toward reducing corrosion in a methanol-to-olefin (MTO) effluent processing system, and particularly in the condensate removal system thereof, by injecting a neutralization agent into one or more target regions of the MTO effluent processing system. The neutralization agent ensures that any localized condensation in the MTO effluent processing system, particularly in the condensate removal system, occurs under basic conditions and that any acidic condensable components are neutralized. The invention is also directed to monitoring corrosion in an MTO effluent processing system and to monitoring the pH of localized corrosion sites in order to ensure proper neutralization of any acidic condensation formed therein.

摘要： Disclosed is a system of making an olefin derivative from a dilute olefin feed. Dilute olefin is sent to an olefin reaction unit to form an olefin derivative product. The olefin derivative product is recovered from the reaction unit while a vent stream is also removed. Olefin is separated from the vent stream, and the olefin is sent to the olefin reaction unit for additional processing.

摘要： The present invention is a process for removing alkynes and/or dienes from an olefin product stream withdrawn from an oxygenate-to-olefins reactor. The process comprises hydrogenating a first olefin stream that has alkynes and/or dienes in the presence of excess hydrogen and a first hydrogenation catalyst. The hydrogenation of the first olefin stream produces a second olefin stream that has unreacted hydrogen. The second olefin stream is contacted with a second hydrogenation catalyst producing a third olefin stream. The third olefin stream has low levels of hydrogen and alkynes and/or dienes.
