Abstract: This invention is directed to removing contaminants from an oxygenate containing feedstream for an oxygenate to olefin reaction system. Oxygenate feeds used in the conversion of oxygenates to olefins, and which contain contaminants, are heated to form a vapor stream and a liquid stream. The heating is conducted so that a majority of the contaminants is contained in the liquid stream. The vapor stream is separated from the liquid stream, and the separated vapor stream is contacted with the metalloaluminophosphate molecular sieve catalyst to form olefin product. The heating of the feedstream and the separation of the vapor stream can be carried out in one or more stages.

Abstract: This invention is directed to a method of removing dimethyl ether from an olefin stream. The method includes distilling the olefin stream so that the dimethyl ether is separated out of the olefin stream with propane. The olefin stream can then be further distilled to provide a polymer grade ethylene stream and a polymer grade propylene stream, with each stream containing not greater than about 10 wppm dimethyl ether.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a process for recovering heat in an oxygenate to olefin ("OTO") production process. The process includes removing heat while maintaining the temperature of an effluent stream that comprises solid particles (typically catalyst particles) and a gas phase comprising prime olefins from an OTO reactor above the dew point temperature of the effiuent stream. The process further includes washing the effluent stream in solids wash to remove the solid particles from the gas phase into a liquid wash medium.

Abstract: This invention is directed to a method of removing dimethyl ether from an olefin stream. Dimethyl ether is removed from the olefin stream by first separating the olefin stream into a first stream comprising dimethyl ether and lighter boiling point compounds, and a second stream comprising C 4 + olefin and higher boiling point hydrocarbons. The dimethyl ether is then separated from the first stream using extractive distillation.
