    摘要: The present invention provides processes for removing CO2 from an effluent stream derived from an oxygenate to olefins reaction system. In one embodiment, the invention comprises contacting the effluent stream with a first CO2 removal medium in a first CO2 removal zone under conditions effective to remove a first portion of the CO2 from the effluent stream and form a first CO2 depleted stream. The first CO2 depleted stream is contacted with a second CO2 removal medium in a second CO2 removal zone under conditions effective to remove a second portion of the CO2 from the first CO2 depleted stream and form a second CO2 depleted stream comprising less than about 0.5 vppm CO2.

    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 technique for recovering heat from a high temperature effluent stream from catalyst regeneration or the like, comprising processes and means for: (a) passing the effluent stream in heat exchange relationship in a steam generator with boiler feed water to produce high pressure steam and partially cool the effluent stream; (b) passing the partially cooled effluent stream from the steam regenerator in heat exchange relationship to preheat high pressure boiler feed water and further cool the effluent stream; and (c) passing the preheated boiler feed water to the steam generator. The apparatus and processes for thermal energy recovery may be used to treat hot regenerator effluent from FCC or OTO-type processes, thereby producing a cooled flue gas stream to discharge to ambient atmosphere.
