The process consists of mixing ammonia or methane with the flue gas and then passing the mixtures through a bed of expanded vermiculite, the latter serving as a catalyst for reactions between the nitorgen oxides and ammonia or methane. The reactions result in the formation of nitrogen and water and/or carbon dioxide.Field of SearchNitrogen or nitrogenous component |
