  • Methods of Deresinating Crude Oils Using Carbon Dioxide
    Publication number: 20100032340
    Abstract: A method of deresinating a crude oil comprises contacting the crude oil with a carbon dioxide containing fluid, the crude oil having an initial API gravity and comprising an oil phase, resins, and asphaltenes, and wherein the carbon dioxide containing fluid enters the oil phase of the crude oil In a manner such that the resins and asphaltenes precipitate out of the crude oil such that the final API gravity of the crude oil is higher than the initial API gravity of the crude oil.
    Type: Application
    Filed: October 16, 2009
    Publication date: February 11, 2010
    Inventors: Nael Naguib Zaki, Peter Kelley Kilpatrick, Ruben Guillermo Carbonell

  • Methods of demulsifying emulsions using carbon dioxide
    Patent number: 6566410
    Abstract: A method of demulsifying a water-in-oil emulsion comprising an oil phase comprising asphaltenes and an aqueous phase is disclosed. The method comprises contacting a carbon dioxide containing fluid with the emulsion such that the carbon dioxide containing fluid enters the oil phase of the emulsion. The asphaltenes precipitate out of the emulsion and the emulsion destabilizes.
