    摘要： This process comprises using unconventional processing of hydrocarbons, e.g. natural gas, for recovering C2+ and NGL hydrocarbons that meet pipeline specifications, without the core high capital cost requirement of a demethanizer column, which is central to and required by almost 100% of the world's current NGL recovery technologies. It can operate in Ethane Extraction or Ethane Rejection modes. The process uses only heat exchangers, compression and simple separation vessels to achieve specification ready NGL. The process utilizes cooling the natural gas, expansion cooling, separating the gas and liquid streams, recycling the cooled streams to exchange heat and recycling selective composition bearing streams to achieve selective extraction of hydrocarbons, in this instance being NGLs. The compactness and utility of this process makes it feasible in offshore applications as well as to implementation to retrofit/revamp or unload existing NGL facilities. Many disparate processes and derivatives are anticipated for its use.

    摘要： Described is a process for degasolining by refrigeration of a gas containing condensable hydrocarbons, which is effected in the presence of methanol to avoid the formation of hydrates, said process making it possible to at least partially recover the methanol entrained in the gas, by washing same by means of a liquid hydrocarbon fraction. The process described thus makes it possible to avoid having to compensate for the loss of methanol by a continuous make-up, as is the case with conventional processes. It accordingly enjoys enhanced levels of performance and economy.

    摘要： This invention comprises a method of producing ethylene rich product streams from a pressurized charge gas mixture of olefins and other components received from olefin generation/preparation processes. The method of this invention may eliminate the need for cryogenic fractional distillation and other special separation equipment operating at temperatures below -55.degree. F., and thus also potentially eliminate the refrigeration and heat exchange equipment needed to achieve those low temperatures. Alternatively, the method of this invention may eliminate the need for a circulating lean oil absorbant material, and thus also potentially eliminate the heat exchange equipment and reduces the refrigeration and fractional distillation load required to manage that material. In accordance with the process of this invention, a secondary ethylene rich product stream is produced at a rate and composition suitable for subsequent generation of a primary ethylene rich product potentially containing substantially no components having a boiling point at least as low as ethylene. Further, the secondary ethylene rich product stream may be suitable as feedstock in the production of ethylene derivatives, or be amenable to further concentration of ethylene using bulk separation techniques, or combinations thereof. Accordingly, the capital and operating cost associated with the manufacture of ethylene rich product streams from pressurized charge gas mixtures made by olefin generation processes may be significantly reduced through the method of this invention.

    摘要： A process for the recovery of propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled and/or expanded to partially condense it, then separated to provide a first vapor stream. The first vapor stream is directed into a contacting device whereby a third vapor stream and a C.sub.3 -containing liquid stream are formed. The C.sub.3 -containing liquid stream is directed to a distillation column wherein a second vapor stream is separated to recover a product containing the major portion of the C.sub.3 components and heavier hydrocarbon components. The second vapor stream is directed into heat exchange relation with the third vapor stream to cool the second vapor stream and condense at least a part of it, forming a condensed stream. At least a portion of the condensed stream is directed to the contacting device to intimately contact the first vapor stream; the remaining portion of the condensed stream is supplied to the distillation column as its top feed. The quantities and temperatures of the feeds to the contacting device and the distillation column are effective to maintain the overhead temperatures of the contacting device and the distillation column at temperatures whereby the major portion of the desired components is recovered.
