Title (EN) PROCESS FOR THE PURIFICATION OF WASTE MATERIALS OR INDUSTRIAL BY-PRODUCTS COMPRISING CHLORINE
(FR) PROCÉDÉ DE PURIFICATION DE DÉCHETS OU DE SOUS-PRODUITS INDUSTRIELS COMPRENANT DU CHLORE
Abstract:
(EN) The present application relates to a process for the purification of waste materials or industrial by-products, the process comprising the steps of: a) Preparing a composition (C) by blending or mixing waste materials or industrial by-products comprising chlorine (B) with one or more materials comprising heavy metals (HM) b) Reacting (B) and (HM) by thermal treatment of (C) c) Separating evaporated heavy metal chloride compounds (HMCC) d) Obtaining a solid material after the thermal treatment step.
(FR) La présente invention concerne un procédé de purification de déchets ou de sous-produits industriels, le procédé comprenant les étapes consistant à : a) préparer une composition (C) par mélange ou regroupement de déchets ou de sous-produits industriels comprenant du chlore (B) avec un ou plusieurs matériaux comprenant des métaux lourds (HM) b) faire réagir (B) et (HM) par traitement thermique de (C) c) séparer les composés chlorure de métaux lourds évaporés (HMCC) d) obtenir un matériau solide après l'étape de traitement thermique.
