    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： The invention relates to a process for modifying tanker ships. More specifically, the invention is directed to a process for modifying a non-methanol-carrying tanker to carry a methanol cargo destined for a methanol to olefin reaction system. The process includes providing a tanker having one or more holds that previously stored a non-methanol material. The process includes one or more of the following steps: (1) cleaning the holds of the crude/naphtha-carrying tanker to remove residual deposits, wherein the holds previously stored a non-methanol material; (2) providing a fire suppression system specially designed to prevent methanol fires; and (3) replacing methanol intolerant pump seals and flange gaskets in the tanker with methanol resistant seals and gaskets.

    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.
