Abstract
PROCEDIMIENTO PARA REDUCIR LA CONCENTRACION DE OXIDOS DE NITROGENO EN UN EFLUENTE DE LA COMBUSTION DE UN COMBUSTIBLE CARBONACEO, AL MISMO TIEMPO QUE SE REDUCE AL MINIMO LA PRODUCCION DE OTROS CONTAMINANTES. EL PROCEDIMIENTO COMPRENDE INTRODUCIR (PREFERENTEMENTE POR INYECCION) UN AGENTE DE TRATAMIENTO PARA LA REDUCCION DE OXIDOS DE NITROGENO EN UN EFLUENTE, DE ACUERDO CON UN REGIMEN DE TRATAMIENTO PARA LA REDUCCION DE OXIDOS DE NITROGENO, EN CONDICIONES TALES QUE EL AGENTE DE TRATAMIENTO OPERA EN EL MARGEN DE ALTA TEMPERATURA O MARGEN DERECHO DE SU CURVA DE REDUCCION DE OXIDOS DE NITROGENO VERSUS TEMPERATURA DEL EFLUENTE, ESPECIALMENTE EN EL MARGEN DE ALTA O MARGEN DERECHO DE LA MESETA DE LA CURVA.
