Abstract

EL CONTENIDO DE NOX EN UNA CORRIENTE DE LOS GASES DE LA COMBUSTION SE REDUCE A BASE DE HACER PASAR A LOS GASES DE LA COMBUSTION A TRAVES DE UNA PRIMERA ZONA DE TRATAMIENTO Y DE UNA SEGUNDA ZONA DE TRATAMIENTO. SE INTRODUCE UN AGENTE DE TRATAMIENTO NITROGENOSO EN LA PRIMERA ZONA DE TRATAMIENTO PARA LA REDUCCION NO CATALITICA SELECTIVA DE PARTE DEL NOX Y A CONTINUACION SE HACE PASAR A LOS GASES DE LA COMBUSTION A TRAVES DE LA SEGUNDA ZONA DE TRATAMIENTO QUE INCLUYE UN CATALIZADOR PARA UNA REDUCCION CATALITICA SELECTIVA ADICIONAL DEL NOX. OPCIONALMENTE, SE PUEDE AÑADIR UN SEGUNDO AGENTE DE TRATAMIENTO NITROGENOSO A LOS GASES DE LA COMBUSTION QUE SE ENCUENTRAN EN LA SEGUNDA ZONA DE TRATAMIENTO. LA CANTIDAD DE NOX PRESENTE EN LOS GASES DE LA COMBUSTION SE DETECTA EN LA ZONA ENTRE MEDIAS DE LA PRIMERA Y LA SEGUNDA ZONAS DE TRATAMIENTO Y, OPCIONALMENTE, DESPUES DE QUE LOS GASES DE LA COMBUSTION HAYAN SALIDO DE LA SEGUNDA ZONA DE TRATAMIENTO. TAMBIEN SE DETECTA LA CANTIDAD DE AMONIACO PRESENTE EN LOS GASES DE LA COMBUSTION QUE SALEN DE LA SEGUNDA ZONA DE TRATAMIENTO. LAS CANTIDADES DE LOS AGENTES DE TRATAMIENTO QUE SE AÑADEN A LOS GASES DE LA COMBUSTION SE CONTROLAN EN RESPUESTA A LAS VARIACIONES Y A LOS NIVELES ABSOLUTOS DETERMINADOS POR ESTAS MEDIDAS.
