  • Controlling crystallization at the interface between oil and brine
    Patent number: 11530996
    Abstract: A method is described for determining the structure of a surfactant complex formed at an immiscible liquid-liquid interface. The surfactant complex forms and crystallizes at the interface between an aqueous phase comprising a divalent metal salt and a non-aqueous phase comprising an anionic surfactant. The non-aqueous phase may be in the form of a droplet surrounded by the aqueous phase. The structure of the surfactant complex is determined by X-ray crystallography.
    Type: Grant
    Filed: March 24, 2020
    Date of Patent: December 20, 2022
    Assignee: King Fahd University of Petroleum and Minerals
    Inventors: Theis Ivan Solling, Safwat Abdelazeim
