Title (EN) APPARATUS AND PROCESS FOR REMOVING CONTAMINANTS FROM SOIL
(FR) PROCEDE ET APPAREIL D'ELIMINATION DE SUBSTANCES CONTAMINANTES DU SOL
Abstract:
(EN) An apparatus and process are described for removing contaminants from soil or other substrate materials. A hot pressurized liquid is continuously supplied to a volume of soil or other material contained in a processing vessel (70). The hot pressurized liquid may be steam, which vaporizes a fraction of the contaminant which is then released through a vapor filter (102) to prevent atmospheric cross-pollution. The remaining contaminant is removed as either a liquid phase or a solid solution phase along with the steam driver. The waste stream and steam driver condense in a collector (90) and are removed from the system. The driver may be recovered for reuse or may be discarded along with the waste stream. The processor may also be used to remove various types of contaminants ranging from light hydrocarbons, chlorinated solvents, and water soluble organics to heavy oils, paints, heavy metals, and radionucleides.
(FR) Appareil et procédé permettant d'éliminer des substances contaminantes du sol ou autres substrats. Un liquide pressurisé chaud est amené en continu dans un volume d'un sol ou autre matière contenue dans une cuve de traitement (70). Le liquide pressurisé chaud peut être de la vapeur, laquelle vaporise une fraction de la substance contaminante qui est alors libérée au travers d'un filtre à vapeur (102) pour prévenir une pollution atmosphérique. L'agent contaminant restant est éliminé soit comme phase liquide soit comme une phase de solution solide en même temps que la vapeur d'entraînement. Le courant de déchets et la vapeur d'entraînement se condensent dans un collecteur (90) et sont éliminés du système. La vapeur d'entraînement peut être récupérée pour être réutilisée ou peut être rejetée en même temps que le courant de déchets. Le processeur peut également être utilisé pour éliminer divers types d'agents contaminants allant de l'hydrocarbure léger, des solvants chlorés et des matières organiques solubles dans l'eau jusqu'au huiles lourdes, les peintures, les métaux lourds et les radionucléides.
