Abstract

PARA EL PROCESO DE ELIMINACION DE POLVO Y DESNITROGENADO SE MEZCLA UN GAS DE ESCAPE DE COMBUSTION CON NH3 Y SE GUIA CON UNA TEMPERATURA EN LA ZONA DESDE APROXIMADAMENTE 250 HASTA 600 C A TRAVES DE UN LECHO FLUIDIZADO TURBULENTO. EL LECHO FLUIDIZADO TURBULENTO DISPONE DE UN CATALIZADOR DE DESNITROGENACION QUE CONTIENE FESO4. EL GAS DE ESCAPE DE COMBUSTION SE UTILIZA EN EL LECHO FLUIDIZADO COMO GAS DE TORBELLINO. EL LECHO FLUIDIZADO SE GUIA AL CATALIZADOR FRESCO DE DESNITROGENACION, QUE SE COMPONE AL MENOS EN EL 90% EN PESO DE FESO4 CONTENIDO EN AGUA CRISTALIZADA CON UN TAMAÑO DE GRANO EN LA ZONA DESDE 1 HASTA 150 MICRAS. EL GAS DE ESCAPE TRATADO ES SOMETIDO A ELIMINACION DE POLVO EN UN ELECTROFILTRO.
