  • Asphaltene aggregation in petroleum oil mixtures determined by small angle light scattering
    Patent number: 6839137
    Abstract: The present invention includes a method to determine if asphaltenes are soluble or insoluble in a solution. The solution may be a petroleum oil, a mixture of petroleum oils, petroleum derived oils and mixtures or similar combinations in a solvent. The invention includes the steps of illuminating the solution with a laser, measuring the small angle scattered light as a function of angle away from the laser beam, and determining if the asphaltenes are soluble or insoluble in the solution.
    Type: Grant

  • Disaggregation of asphaltenes in incompatible petroleum oil mixtures
    Publication number: 20040089589
    Abstract: The present invention is a method to disaggregate asphaltenes in petroleum oils and oil mixtures by mild heating. The presence of asphaltenes is determined by small angle neutron scattering.
