Abstract

L'invention concerne un système et un procédé permettant de délivrer un fluide sursaturé en gaz. Ce système comprend un réservoir (12) de fluide, une pompe à fluide (14), une source de gaz (16), un échangeur (18) de gaz haute pression, et un ou plusieurs réseaux de canaux (20) capillaires. Des commandes appropriées, par exemple un manomètre (22) différentiel ou des soupapes à pression différentielle, permettent de maintenir une pression hydrostatique presque constante du fluide à l'intérieur de l'interface (26) gaz-fluide à membrane semi-perméable dudit échangeur de gaz, cette pression étant environ 1 à 20 % supérieure à la pression partielle gazeuse du fluide situé à l'intérieur de l'échangeur de gaz. Le fluide sursaturé en gaz s'écoule depuis l'échangeur de gaz par l'intermédiaire des canaux capillaires, à une vitesse d'écoulement supérieure à 0,05 m/sec, ce qui facilite la délivrance de débits élevés de fluides sursaturés en gaz, sans effet de cavitation.
