Abstract

La présente invention se rapporte d'une manière générale au domaine de l'équipement de contrôle d'émission conçu pour des chaudières, réchauffeurs, séchoirs ou autres dispositifs dégageant des gaz de carneau ou de combustion (par ex. situés au sein des centrales électriques, usines de traitement et autres) et notamment à un procédé et un appareil novateurs et utiles permettant de réduire ou de prévenir l'empoisonnement et/ou la contamination d'un catalyseur SCR. Selon un autre mode de réalisation, la présente invention se rapporte à un procédé et un appareil permettant de prolonger la vie utile et/ou l'activité catalytique d'un catalyseur SCR tout en contrôlant simultanément diverses émissions. Selon un autre mode de réalisation, la présente invention se rapporte à un procédé et un appareil permettant de réguler, atténuer et/ou réduire la quantité de sélénium contenue dans et/ou émise par une ou plusieurs pièces d'équipement de régulation d'émission conçu pour des chaudières, réchauffeurs, séchoirs ou autres dispositifs dégageant des gaz de carneau ou de combustion (par ex. situés au sein des centrales électriques, usines de traitement et autres).
