    摘要: A bundle of spoolable power supplying and heating cables and at least one weight-supporting strand for forming an assembly for electrically heating or heating and logging a long interval of subterranean earth formations is installed within a well by spooling superposed flat layers of those strands and an interspersed flexible band on a drum substantially as narrow as the layers, while interconnecting the power supplying and heating cables on the drum, and then unspooling the strands into the well while intermittently banding them into bundles and concurrently respooling the flexible band on a different drum.

    摘要: This invention provides a methanol composition, a method of making the composition, and a method of using the composition. The methanol composition of this invention is supplemented with certain additional alcohols and/or aldehydes, and serves as a particularly desirable feed stream for use in the manufacture of olefins such as ethylene and propylene. Such feed streams result in increased production of ethylene or in the increased production of both ethylene and propylene.

    摘要: The invention relates to a process for converting an oxygenate feedstock into an olefin product stream comprising (a) contacting an oxygenate feedstock with a molecular sieve catalyst in a reactor under conditions effective to convert the feedstock into an olefin product stream and to form carbonaceous deposits on the catalyst; (b) contacting at least a portion of the catalyst having said carbonaceous deposits with an oxygen containing gas under conditions effective to obtain a regenerated catalyst having a reduced carbonaceous deposit level and having an increased molecular oxygen content; (c) removing at least 60% by volume of said molecular oxygen from the regenerated catalyst based upon the total volume of molecular oxygen; (d) returning said regenerated catalyst to said reactor; and (e) repeating steps (a)–(d).

    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.
