摘要： Disclosed is a method of removing dimethyl ether from an ethylene and/or propylene containing stream. Dimethyl ether is removed at a high pressure, preferably in a distillation column. The high pressure separation has the benefit of providing a relatively low bottoms temperature separation, while allowing for recovery of a highly concentrated ethylene and/or propylene stream.

摘要： The present invention provides new highly-efficient separation processes and systems for separating polymerization-grade ethylene and propylene from an initial effluent stream comprising ethane, ethylene, propylene, dimethyl ether, and one or more of propane, acetylene, methyl acetylene, propadiene, methane, hydrogen, carbon monoxide, carbon dioxide and C4+ components. In one embodiment, the initial effluent stream is provided from a methanol-to-olefin reaction system. It has been discovered that the best separation of these components is realized when DME is selectively removed in a first separation step, followed by separation of the remaining components in additional separation steps.

摘要： 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 metalloaluminophosphate molecular sieve catalyst 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.

摘要： A feed vaporization process and apparatus for oxygenate to olefin conversion is provided, which uses a vapor-liquid disengaging drum to separate non-volatiles and/or low-volatiles from volatiles in the oxygenate feed and produce a vaporized effluent that is reduced in non-volatiles and/or low-volatiles while at the same time maintaining the effluent at optimal temperature and pressure as a feed for oxygenate to olefin conversion. The feed vaporization process and apparatus is particularly well suited for selectively removing non-volatile contaminants such as soot and rust from an oxygenate-containing feed, which may have become contaminated during shipping.

摘要： A method for producing an olefin stream is provided based on conversion of an initial natural gas stream into a synthesis gas. The resulting synthesis gas is enriched with CO2 previously separated from the natural gas stream. The synthesis gas is then used to form a methanol composition, which can then be used as feedstock for a methanol-to-olefin conversion reaction.

摘要： This invention is directed to methods for forming an olefin stream from a methanol stream. A lower grade methanol, such as chemical grade or crude methanol, can be used as feed to form the olefin stream. The process uses a relatively simple distillation type step to vaporize a portion of the methanol feed stream and send the resulting vapor stream to a reaction unit to form the olefin stream. In addition, the invention provides the ability to operate the downstream recovery units with reduced fouling or plugging due to the presence of fine solids components.
