  • Patent number: 8444849
    Abstract: This invention relates to devices and processes for removing asphaltenes and/or metals from crude oil to increase refinery processing of heavy materials. The desalters of this invention reduce and/or remove at least a portion of asphaltenes and/or metals form the crude oil. The separation occurs by mixing water with the crude oil to result in an aqueous phase having water and water soluble salts, an interface phase having asphaltenes and/or metals along with water, and a hydrocarbon phase haying desalted, deasphalted and/or reduced metal crude oil.
    Type: Grant
    Filed: March 30, 2012
    Date of Patent: May 21, 2013
    Assignee: BP Corporation North America Inc.
    Inventors: Sudhakar Chakka, Steve E. Orwig, Joachim Voelkening

  • Publication number: 20100326880
    Abstract: This invention relates to a hydrocarbon conversion process additive and related processes, such as upgrading a heavy hydrocarbon material and making sponge coke. The hydrocarbon conversion process additive works with thermal processes, catalytic processes, or thermal-catalytic processes. The hydrocarbon process conversion additive includes lignin or macromolecular substructures of lignin like para-coumaryl alcohol, coniferyl alcohol, or sinapyl alcohol.
