Abstract: A process for controlling an oxygenates to olefin reactor is disclosed which comprises: contacting oxygenate-containing feedstock, e.g., methanol, in a reaction zone in the presence of a molecular sieve catalyst under conditions sufficient to provide an olefins-containing effluent containing alkyl alcohol and dialkyl ether, e.g., methanol and dimethyl ether; analyzing a single gas phase of the effluent determine alkyl alcohol concentration; and adjusting reactor conditions, e.g., WHSV, as a function of alkyl alcohol concentration and dialkyl ether concentration, as necessary to provide a substantially consistent effluent composition. A corresponding apparatus for carrying out the process is also provided.

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 present invention is a process for producing olefin(s) from oxygenate(s). The process removes oxygenate(s) including carbon dioxide in the bottoms of the quench stream and recycles the oxygenate(s) back to the reactor. Carbon dioxide is removed from the quench bottoms before returning oxygenate(s) in the quench bottoms stream to the reactor.

Abstract: The present invention is a process for removal of carbon dioxide from a reactor effluent stream comprising water, carbon dioxide and olefin(s), where a portion of the carbon dioxide is removed in a quenching step with a quench medium and more carbon dioxide is removed by contacting the quenched effluent stream with an alkaline stream. A portion of the alkaline stream is added to the quench medium.

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.
