Title (EN) DEVICE FOR THE IN SITU EXTRACTION OF DISSOLVED GAS AND CORRESPONDING MEASURING APPARATUS
(FR) DISPOSITIF D'EXTRACTION IN SITU DE GAZ DISSOUS ET APPAREIL DE MESURE CORRESPONDANT
Abstract:
(EN) The invention concerns a device (1) for the in situ extraction of gas dissolved in a liquid medium, the device (1) comprising: - a tank (11) of solvent that is immiscible with the liquid, - an inlet channel (12) for liquid from the liquid medium, - a module (14, 15) for inducing the flow of the solvent and the liquid, - a tubular chamber (13) traversed from one end to the other by a mixture of the solvent originating from the tank (11) and the liquid originating from the inlet channel (12) in order to transfer the gas from the liquid to the solvent, - a settling tank (16) arranged to receive the mixture of the solvent and the liquid through an inlet (160) and to then allow the mixture to be separated by gravity into two phases, a first denser phase of which is situated at the bottom of the settling tank and a second lighter phase of which is situated at the surface of the settling tank.
(FR) L'invention concerne un dispositif (1) d'extraction in situ de gaz dissous en milieu liquide, le dispositif (1) comportant: - un réservoir (11) de solvant non miscible dans le liquide, - un canal (12) d'admission de liquide du milieu liquide, - un module (14, 15) de mise en circulation du solvant et du liquide, - une enceinte (13) tubulaire traversée d'une extrémité à l'autre par un mélange du solvant provenant du réservoir (11) avec le liquide provenant du canal (12) d'admission pour un transfert du gaz du liquide vers le solvant, - un décanteur (16) agencé pour recevoir par une entrée (160) le mélange du solvant avec le liquide puis pour permettre la séparation par gravité du mélange en deux phases dont une première phase plus dense située au fond du décanteur et une deuxième phase plus légère située en surface du décanteur.
