  • Publication number: 20140197071
    Abstract: Systems and methods are provided for using field enhanced separations to produce multiple fractions from a petroleum input. A liquid thermal diffusion and/or electric field separation is used to produce the fractions. The fractions can then be used to form multiple outputs that share a first feature while being different with regard to a second feature. For example, a first fraction from the plurality of fractions can have a desired value for a first property such as viscosity index. Two or more additional fractions from the plurality of fractions can then be blended together to make a blended fraction or output. The blended fraction can have a value for the first property that is substantially similar to the value for the first fraction. However, for a second property, the first fraction and the blended fraction can have distinct values. As a result, multiple output fractions can be formed that share a first feature but differ in a second feature.

  • Patent number: 7803270
    Abstract: A process is described for the extractive oxidation of contaminants present in raw fuel streams rich in heteroatomic polar compounds and catalyzed by iron oxides contained in natural limonitic goethite, said process comprising contacting said streams with an oxidation pair which is a peroxide in solution/organic acid in amount of at least 3 and an amount between 0.01 and 10 wt % of an iron oxide, both based on the feed, the iron oxide being made up of a reduced natural limonitic goethite. The goethite reduction by a hydrogen stream has the advantage of lowering the migration of non-contaminating polar hydrocarbons from the fuel stream to the aqueous phase, at the same time obtaining higher mass yield of final product fuel while the level of target contaminants to be removed is maintained relative to the state-of-the-art process. Process yields attain 98% weight/weight.

    Abstract: The present invention relates to improving heavy crude oil, and extra through a scheme considering the use of ionic liquids catalysts based on Mo and Fe catalyst is highly miscible with crude oil and are in the homogeneous phase crude oil. Furthermore, this invention relates to improving heavy crude in two stages, the first ionic liquid catalyst, and the second supported catalyst. The API gravity crude is increased from 12.5 to 19 points in the first stage and viscosities up to 5600-1600 decreased from 60-40 cSt certain to 37.8 ° C. While in the second stage, you get an upgraded crude oil with 32.9 ° API, viscosity of 4.0 cSt, reduction in total sulphur content of 0.85 wt % nitrogen and 0295 ppm by weight, respectively. As a considerable reduction of asphaltenes from 28.65 to 3.7% weight.

  • 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.

  • Publication number: 20090286890
    Abstract: The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises at least 50 vol. % of the extracted gas. The extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst at a temperature of less than 600° C. to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid hydrocarbon or a liquid hydrocarbon oxygenate.
