Title (EN) METHOD FOR PURIFYING FUME CONTAMINATED BY HYDROGEN CHLORIDE AND HEAVY METALS, RENDERING INERT SAID HEAVY METALS AND UPGRADING SAID HYDROGEN CHLORIDE
(FR) PROCEDE POUR EPURER UNE FUMEE CONTAMINEE PAR DU CHLORURE D'HYDROGENE ET DES METAUX LOURDS, INERTER LESDITS METAUX LOURDS ET VALORISER LEDIT CHLORURE D'HYDROGENE
Abstract: front page image
(EN)The invention concerns a combined method for purifying fume contaminated by hydrogen chloride and heavy metals, rendering inert the heavy metals and upgrading the hydrogen chloride, which consists in: subjecting the fume (6) to a treatment, by dry or semi-humid process, with a basic reagent (8) comprising a soda compound; collecting from said treatment a solid residue (13) containing the heavy metals; dispersing the solid residue and a hydraulic binder (18) in water (20) to form an aqueous broth (21); and extracting from the broth the solid mass (28) which is eliminated, and an aqueous solution (29).
(FR)Procédé pour, en combinaison, épurer une fumée contaminée par du chlorure d'hydrogène et des métaux lourds, inerter les métaux lourds et valoriser le chlorure d'hydrogène, selon lequel on soumet la fumée (6) à un traitement, par voie sèche ou semi-humide, avec un réactif basique (8) comprenant un composé sodique, on recueille de ce traitement un résidu solide (13) contenant les métaux lourds, on disperse le résidu solide et un liant hydraulique (18) dans de l'eau (20) pour former un brouet aqueux (21) et on extrait du brouet, d'une part une masse solide (28), que l'on écarte, et, d'autre part, une solution aqueuse (29).
