Fractionation Patents (Class 208/308)
  • Patent number: 11725147
    Abstract: Methods, processes and devices are described for measuring a volatile content of a process stream that comprises volatile species, such as light hydrocarbons and/or H2S. The method can include introducing a stripping gas into a sample of the process stream to strip the volatiles therefrom and produce a gas phase comprising vaporized volatiles; detecting the vaporized volatiles in the gas phase to obtain a sample volatile content; and determining the volatile content of the process stream based on the sample volatile content. The method and device can be used to measure a light hydrocarbon content of froth treatment tailings in the context of removing such light hydrocarbons prior to flocculating and dewatering the tailings.

The anti-fouling mechanisms with high mitigation rates can be deployed at only the hottest portions of a pre-heat train that experience the highest rates of fouling and heat loss. In application, bundles of corrosion resistant smoothed tubes are deployed in the late pre-heat train to significantly reduce the formation of harder deposits. Vibration can be used as an adjunct approach in conjunction with the corrosion resistant, smooth tubes, or deployed alone on existing bundles. The use of high performing, more durable exchangers in select locations justifies the increased cost of these components.

    Abstract: A liquid feed material such as a heavy hydrocarbon feed in liquid form is contacted with a fluidized bed of heated solid particles which have a bulk horizontal velocity which is generally perpendicular to the flow of a fluidizing medium. The liquid feed material reacts on the solid particles to produce a vapor phase product, which vapor phase product is collected in a vapor collection apparatus.

  • Patent number: 8197562
    Abstract: The feeding of coal slurries into a gasifier for the production of synthesis gas is improved by modifying the rheological properties of the coal particles so that conventional liquid transfer equipment can be used in the feed transfer process to the gasifier. The coal particle surface modification is accomplished by adsorbing asphaltenes derived from petroleum onto the surfaces of coal particles prior to and/or during contact with the slurry liquid. The coal particles with their surfaces thus modified exhibit lower particle-particle interaction in the liquid slurries to form a shear independent Newtonian fluid or a weakly shear thickening pseudoplastic fluid. The rheological properties of the slurries permit them to be transported reliably into a pressurized, entrained feed gasifier vessel using convention slurry pumps with a low potential expenditure of energy.

  • Patent number: 8177965
    Abstract: This invention relates to an ultrafiltration process for separating a heavy hydrocarbon stream to produce an enriched saturates content stream(s) utilizing an ultrafiltration separations process. The enriched saturates content streams can then be further processed in refinery and petrochemical processes that will benefit from the higher content of saturated hydrocarbons produced from this separations process. The invention may be utilized to separate heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, oils derived from bitumen, oils derived from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams into enriched saturates content product streams. The invention provides an economical method for separating heavy hydrocarbon stream components by molecular species instead of molecular boiling points.

  • Publication number: 20120000830
    Abstract: A process for upgrading bitumen recovered from an oil reservoir without hydrogen production is particularly useful in field upgrading applications. In this process, recovered bitumen enters a fractionator and is contacted with heated gases from a fluidized bed reactor. The bitumen and heated gases are fractionated into segregated products including at least a liquid pitch, unstable fractions, and an upgraded liquid product. The liquid pitch is introduced into the reactor to produce a vapor phase liquid product; the reactor comprises solid particles moving through the reactor and a fluidizing gas fluidizing the solid particles at a conversion temperature which is suitable for facilitating the conversion of at least some of the liquid pitch into the vapor phase liquid product. The heated gases comprising the vapor phase liquid product and fluidizing gas are directed from the reactor to the fractionator to contact the bitumen stream.

  • Publication number: 20110240526
    Abstract: A device for use in separating debris from a flowing stream which comprises a substantially hollow, substantially conical shaped structure comprising a top end member and a plurality of adjacently positioned side members angularly extending from a top end member to a substantially circular bottom end. The top end member has a smaller diameter than the circular bottom end. The adjacently positioned side members are configured to provide multiple tiers in a vertical plane in the conically shaped structure. The multiple tiers comprise a plurality of apertures in a horizontal plane in the conically shaped structure. The plurality of apertures are configured for separating large debris particles, generally formed from coke and spent catalyst, from a flowing fluidized catalytic cracking stream, and directing the captured debris toward the circular bottom end of the device. A method of separating debris from a flowing stream is also provided.

  • Patent number: 7806965
    Abstract: Produced natural gas containing carbon dioxide is dehydrated and chilled to liquefy the carbon dioxide and then fractionated to produce a waste stream of liquid carbon dioxide and hydrogen sulfide. Natural gas liquids may be first separated and removed before fractionation. After fractionation, the waste stream is pressurized and transmitted to a remote injection well for injection either for disposal of the waste stream and preferably to urge hydrocarbons toward the producing well. A hydrocarbon stream proceeds from fractionation to a methanol absorber system which removes carbon dioxide gas. The hydrocarbon stream is thereafter separated into at least hydrocarbon gas, nitrogen and helium. Some of the nitrogen is reintroduced into a fractionation tower to enhance the recovery of hydrocarbons. A methanol recovery system is provided to recover and reuse the methanol. The hydrocarbons are sold as natural gas and the helium is recovered and sold. Excess nitrogen is vented.

  • Patent number: 7767076
    Abstract: The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercritical water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.
