Abstract
Dans le procédé d'amélioration du conditionnement des agents gazéifiants, consistant en de l'eau à l'état liquide et en un gaz contenant de l'oxygène, utilisés dans les procédés de gazéification souterraine, l'eau, préalablement à son injection dans le gisement, est mélangée à une faible dose d'agent moussant et l'eau et le gaz oxydant sont traités dans un générateur de mousse fonctionnant sous pression avant d'etre injectés conjointement dans le gisement, sous la forme d'une mousse constituant un mélange diphasique stable et homogène.In the process for improving the conditioning of gasifying agents, consisting of liquid water and an oxygen-containing gas, used in underground gasification processes, water, prior to its injection into the deposit is mixed with a low dose of foaming agent and the water and the oxidizing gas are treated in a foam generator operating under pressure before being jointly injected into the deposit, in the form of a foam constituting a stable and homogeneous two-phase mixture.
