  • Devices and processes for deasphalting and/or reducing metals in a crude oil with a desalter unit
    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.
