Patent

CA 2360408

The invention provides processes for decontamination of organic halides in asphalt-containing wastes, such as PCBs in asphaltic potting compounds. The processes may use hydrocarbon solvents to dissolve the asphaltic waste, and an alkali metal reactant, such as a sodium dispersion, to destroy the organic halides in the dissolved mixture.

La présente invention a pour objet des procédés de décontamination d'halogénures organiques dans des résidus contenant de l'asphalte, par exemple des BPC dans des matériaux d'enrobement à base d'asphalte. Pour lesdits procédés, on peut utiliser des solvants hydrocarbonés pour dissoudre les déchets contenant de l'asphalte et un réactif à base d'un métal alcalin, par exemple une dispersion de sodium, pour détruire les halogénures organiques contenus dans le mélange dissous.
