Abstract

Procédé utilisant de l'ammoniac pour éliminer simultanément les oxydes de l'azote et les oxydes du soufre de gaz de combustion. Les gaz de combustion passent par un procédé connu d'enlèvement de NOx puis par un procédé connu d'enlèvement des oxydes de S. La quantité totale de NH3 nécessaire est introduite avant ces deux procédés. Application : purification de gaz de combustion avant leur départ à l'atmosphère.
