  • Optimised method for detecting the formation gas hydrates
    Patent number: 10935493
    Abstract: The present invention relates to a method for detecting the presence of gas hydrates and/or ice in a medium. The method comprises at least the following steps: measuring at least at one measurement point in said medium two characteristic values of Raman spectra corresponding to two distinct vibration modes of the OH bonds of water, and determining the ratio ? of said two characteristic values, determining the temperature T in said medium at said measurement point of said spectra, comparing ratio ? with a value ?0 corresponding to a predetermined threshold of formation of said crystals for said temperature T, and determining the presence or not of hydrate and/or ice crystals from said comparison.
    Type: Grant

    Date of Patent: March 2, 2021
    Assignee: IFP ENERGIES NOUVELLES
    Inventors: Olivier Delpoux, Didier Frot, Anne Sinquin, Corinne Sagnard, Veronique Lachet
  • Simplified device for detecting the formation of gas hydrates
    Patent number: 10775311
    Abstract: The device for detecting the presence of gas hydrates and/or ice according to the invention comprises at least: a laser source, at least two band-pass filters, at least one APD detector, at least one means for measuring the temperature at the measurement point, and means for analysing the presence or not of hydrates and/or ice at the measurement point.
