Title (EN) RESERVOIR MONITORING BY ACOUSTIC EMISSION
(FR) CONTRÔLE DE RÉSERVOIR PAR ÉMISSION ACOUSTIQUE
Abstract:
(EN) The present invention relates to a method of monitoring a reservoir, in particular a reservoir made of composite material, preferably intended for storing gas at high pressure, the reservoir being provided with at least one acoustic sensor, the method being characterized in that it comprises the following steps: filling the reservoir with a fluid, acquiring data relating to the amplitude and the energy of acoustic emissions resulting from the filling, with the aid of the sensor or sensors, determining a critical threshold value (Sc) on the basis of a linear combination between data relating to the amplitude and the energy, as a function of this critical threshold value (Sc), deducing therefrom a state of the reservoir. The invention also relates to an installation for implementing the aforesaid method.
(FR) La présente invention concerne un procédé de contrôle d'un réservoir, notamment d'un réservoir en matériau composite, préférentiellement destiné au stockage de gaz sous haute pression, le réservoir étant pourvu d'au moins un capteur acoustique, le procédé étant caractérisé en ce qu'il comprend les étapes suivantes : remplir le réservoir d'un fluide, acquérir des données relatives à l'amplitude et l'énergie d'émissions acoustiques résultant du remplissage, à l'aide du ou des capteur(s), déterminer une valeur seuil critique (Sc) à partir d'une combinaison linéaire entre des données relatives à l'amplitude et l'énergie, en fonction de cette valeur seuil critique (Sc), en déduire un état du réservoir. L'invention concerne également une installation pour la mise en œuvre du procédé précité.
