Title
(EN) CONDITIONING SYSTEM AND METHOD FOR USE IN THE MEASUREMENT OF MERCURY IN GASEOUS EMISSIONS
(FR) SYSTEME DE CONDITIONNEMENT ET PROCEDE UTILISE POUR LA MESURE DU MERCURE DANS DES EMISSIONS GAZEUSES
Abstract
(EN)
Embodiments of the invention relate generally to systems used to measure mercury in gaseous emissions. In one aspect, the invention is directed to the use of an inert covalently bonded material selected from silicon carbide (SiC), silicon oxides (SiOn, n = 1-2), silicon nitride (e.g. Si3N4), silicon boride (e.g. SiB6), boron nitride (e.g. BN) and mixtures thereof as material for a thermal pyrolysis unit. In another aspect, the invention is directed to an improved pyrolyzer design, in which a thermal pyrolysis unit comprises a tailpiece that allows water to be injected at the heated exit of the thermal pyrolysis unit. In another aspect, the invention is directed to the use of a coalescing filter in a scrubbing unit. In another aspect, the invention is directed to the use of a hydrophobic filter element in a scrubbing unit. One or more of these elements may be used in a conditioning module of a continuous emissions monitoring system, for example.

Les modes de réalisation de l'invention concernent généralement des systèmes utilisés pour mesurer le mercure dans des émissions gazeuses. Dans un aspect, l'invention a pour objet l’utilisation d’un matériau inerte lié par covalence choisi parmi le carbure de silicium (SiC), des oxydes de silicium (SiOn, n = 1 à 2), un nitrure de silicium (par exemple, Si3N4), un borure de silicium (par exemple, SiB6), un nitrure de bore (par exemple, BN) et leurs mélanges en tant que matériau destiné à une unité de pyrolyse thermique. Dans un autre aspect, l'invention a pour objet un modèle de pyrolyseur amélioré, dans lequel une unité de pyrolyse thermique comprend un embout permettant à l'eau d'être injectée à la sortie chauffée de l'unité thermique de pyrolyse. Dans un autre aspect, l'invention a pour objet l'utilisation d'un filtre coalescent dans une unité de frottement. Dans un autre aspect, l'invention a pour objet l'utilisation d'un élément filtrant hydrophobe dans une unité de frottement. Un ou plusieurs de ces éléments peuvent être utilisés, par exemple, dans un modul de conditionnement d'un système de surveillance d'émissions en continu.
