Title (EN) COMPLEXATION AND REMOVAL OF MERCURY FROM FLUE GAS DESULFURIZATION SYSTEMS
(FR) COMPLEXATION ET ÉLIMINATION DE MERCURE DE SYSTÈMES DE DÉSULFURATION DE GAZ DE COMBUSTION
Abstract:
(EN) A method for the reduction and prevention of mercury emissions into the environment from combusted fossil fuels or off-gases having mercury with the use of hypoiodite is disclosed. The hypoiodite is used for the capture of mercury from the resulting flue gases using a flue gas desulfurization system or scrubber. The method uses hypoiodite in conjunction with a scrubber to capture mercury and lower its emission and/or re-emission with stack gases. The method allows the use of coal as a cleaner and environmentally friendlier fuel source as well as capturing mercury from other processing systems.
(FR) L'invention concerne un procédé de réduction et de prévention des émissions de mercure dans l'environnement à partir de combustibles fossiles brûlés ou de dégagements gazeux comprenant du mercure au moyen d'hypoiodite. L'hypoiodite est utilisé pour la capture de mercure à partir des gaz de combustion obtenus au moyen d'un système de désulfuration de gaz de combustion ou d'un épurateur. Le procédé utilise l'hypoiodite conjointement avec un épurateur pour capturer le mercure et réduire son émission et/ou sa réémission avec des gaz de carneau. Le procédé permet l'utilisation de charbon comme nettoyant et source de carburant plus écologique ainsi que la capture de mercure à partir d'autres systèmes de traitement.
