Title
(EN) METHOD AND DEVICE FOR REGULATED INJECTION OF LIQUID CARBON DIOXIDE IN A PRESSURISED LIQUID
(FR) PROCEDE ET DISPOSITIF D'INJECTION REGULEE DE DIOXYDE DE CARBONE LIQUIDE DANS UN LIQUIDE SOUS PRESSION
Abstract
(EN)
The invention concerns a novel method (and its associated device) for regulated injection of liquid carbon dioxide (CO2L) in a pressurised liquid (L) inside a chamber. The invention is characterised in that said liquid carbon dioxide (CO2L) is injected at a fixed timed flow rate protected by a gas stream (whenever the injection stops).
(FR)
La demanderesse propose un nouveau procédé (et son dispositif associé) d'injection régulée de dioxyde de carbone liquide (CO2L) dans un liquide (L) sous pression à l'intérieur d'une enceinte. Ledit dioxyde de carbone liquide (CO2L) est, selon celui-ci, injecté à un débit fixe, en mode cadencé, sous protection d'un flux gazeux (lors des arrêts d'injection).
