Abstract

L'invention concerne le développement d'un procédé permettant la détection de mercure dans des gaz d'échappement. Tous les procédés connus destinés au traitement de gaz d'échappement se déroulent par voie humide ou avec des 'réacteurs thermocatalytiques', ce qui permet d'éviter toute réaction secondaire importante due aux parties constituantes autres que le mercure contenues dans les gaz d'échappement. Le but de l'invention est de développer un procédé de conversion fiable de composés Hg en Hg(el) mesurable, lequel procédé ne présente pas les réactions secondaires citées en présence d'autres composantes de gaz de combustion. On utilise un procédé basse température faisant intervenir du cuivre ou des alliages de cuivre comme matériau catalyseur pour la conversion de composés de mercure en mercure élémentaire. Est particulièrement adapté l'alliage de mercure tombac RG7. Ce matériau offre l'avantage de se lier à des halogènes libres et ainsi d'empêcher les réactions inverses en halogénures de mercure. En raison des basses températures, ce procédé n'entraîne pas la transformation de SO2 en SO3, aucune attaque supplémentaire de la surface métallique de l'appareil métallique ne se produit. Le gaz de mesure parcourt un convertisseur Hg dans lequel les composés Hg oxydés (par exemple HgCl2) se transforment Hg élémentaire à l'aide du cuivre (ainsi que d'autre métaux contenus dans le tombac : Sn, Zn, Pb). La détermination des gaz d'échappement dans les centrales à charbon, les incinérateurs d'ordures, les cimenteries.
