PROCEDE D'IDENTIFICATION ET DE QUANTIFICATION DES PROPORTIONS RELATIVES DES DIFFERENTES FRACTIONS CRISTALLISEES PRESENTES DANS UN COULIS D'HYDRATE ET SON UTILISATION POUR LES FLUIDES FRIGOPORTEURS
The invention relates to a method for the identification and quantification of the relative proportions of the different crystallised fractions and liquid present in a hydrate slurry, defined as a solid suspended in a carrier fluid, characterised in that it is carried out by means of a low-field nuclear magnetic resonance spectrometer and a radiofrequency probe allowing the detection and quantification of the protons by direct measurement on said hydrate slurry. The hydrate slurry is, for example, composed of an alkyl-onium clathrate hydrate. The invention is applicable to the identification, the characterisation and the quantification of the different polymorphs of hydrates formed in diphase coolants, in a static or dynamic mode.
