Abstract

LAS EMISIONES DE OXIDOS DE NITROGENO (NOX) PROCEDENTES DE UN REGENERADOR FCC (30) SON REDUCIDAS HACIENDO FUNCIONAR EL REGENERADOR EN MODO DE COMBUSTION DEL CO PARCIAL Y CONTROLANDO EL PROCESADO TERMICO Y CATALITICO DEL GAS DE SALIDA. LA REGENERACION PRODUCIDA EN EL MODO DE COMBUSTION DEL CO PARCIAL PRODUCE UN GAS DE SALIDA CON PRECURSORES DE CO Y DE NOX. ESTE GAS DE SALIDA SE PASA A TRAVES DE UNA LINEA DE TRANSFERENCIA (36) A LA CUAL SE AÑADE AIRE A TRAVES DE CONDUCTOS (41, 53) PARA CONVERTIR HOMOGENEAMENTE LA MAYORIA DE LOS PRECURSORES DE LOS NOX EN NOX A LA VEZ QUE SE DEJA ALGO DE CO SIN CONVERTIR. LA CONVERSION CATALITICA CORRIENTE ABAJO EN UN REACTOR CATALITICO (89) REDUCE A CONTINUACION EL NOX PRODUCIDO CON CO SIN CONVERTIR.
