Abstract
L'invention concerne un procédé de purification des gaz d'échappement provenant d'un processus de combustion, comprenant les étapes qui consistent à : 1) effectuer un processus de combustion; 2) effectuer un processus de séparation solide au cours duquel la concentration en soufre dans les gaz d'échappement provenant du processus de combustion est réduite par addition d'un additif; 3) effectuer un processus de purification catalytique au cours duquel la concentration en oxyde d'azote dans les gaz d'échappement provenant du processus de combustion est réduite par addition d'un agent réducteur, les étapes 1), 2) et 3) étant suivies par une mesure d'une variable des gaz d'échappement, la variable mesurée étant sélectionnée dans le groupe comprenant température, pression, teneur en eau, teneur en soufre, teneur en oxyde d'azote, teneur en agent réducteur ou une combinaison de ceux-ci; la quantité d'additif ajouté à l'étape 2) étant régulée en fonction de la variable mesurée des gaz d'échappement; et/ou la quantité de l'agent réducteur ajouté à l'étape 3) étant régulée en fonction de la variable mesurée des gaz d'échappement; l'agent réducteur étant de préférence ajouté directement dans le processus de combustion de l'étape 1), la quantité de l'agent réducteur ajouté à l'étape 1) étant régulée en fonction de la variable mesurée des gaz d'échappement. L'invention concerne également un procédé de purification de gaz d'échappement contenant du soufre provenant d'un processus de combustion, comprenant un procédé de purification catalytique au cours duquel la concentration en oxyde d'azote dans les gaz d'échappement est réduite par addition continue d'un agent réducteur, la quantité de l'agent réducteur ajouté étant régulée en fonction d'une variable mesurée des gaz d'échappement, et la quantité de l'agent réducteur ajouté étant remise à zéro pendant une durée définie pendant le processus de purification catalytique. L'invention concerne en outre un dispositif de combustion à purification des gaz d'échappement au cours duquel les procédés peuvent être mis en œuvre.
