Abstract
PROCEDE D'ELIMINATION DES HYDROCARBURES AROMATIQUES HALOGENES, DES HUILES HYDROCARBONEES OU A BASE DE SILICONES. IL CONSISTE A TRAITER L'HUILE CONTAMINEE AVEC UNE DISPERSION DE SODIUM DANS UN HYDROCARBURE, LA DIMENSION DES PARTICULES DE SODIUM ETANT COMPRISE ENTRE 1 ET 20MICRONS, A UNE TEMPERATURE SUPERIEURE A 75C, PUIS A FAIRE PASSER L'HUILE, AINSI TRAITEE, PAR DES MOYENS DE SEPARATION, EN PARTICULIER MOYENS DE FILTRATION ET MILIEUX ABSORBANTS HYDRATES, POUR ELIMINER LES PARTICULES ET AUTRES SOUILLURES. IL PERMET NOTAMMENT D'ELIMINER LES DIPHENYLS POLYCHLORES OU POLYBROMES DES HUILES UTILISEES COMME DIELECTRIQUES DANS LES TRANSFORMATEURS ET CONDENSATEURS.
