Abstract
PROCEDIMIENTO PARA LA REDUCCION DE MINERAL DE HIERRO PARTICULADO EN UN REACTOR DE CUBA VERTICAL DE LECHO MOVIL, EL CUAL TIENE UNA ZONA DE REDUCCION DONDE EL MINERAL DE HIERRO ES REDUCIDO A HIERRO ESPONJA.COMPRENDE LAS SIGUIENTES OPERACIOBES: PRIMERA, SE ALIMENTA UN GAS REDUCTOR CALIENTE, COMPUESTO EN SU MAYOR PARTE POR HIDROGENO, MONOXIDO DE CARBONO Y VAPOR DE AGUA, A TRAVES DE LA ZONA DE REDUCCION PARA REDUCIR EL MINERAL ALLI CONTENIDO; SEGUNDA, SE EXTRAE EL GAS REDUCTOR AGOTADO DE DICHA ZONA DE REDUCCION, EL CUAL TAMBIEN ESTA DESHIDRATADO; TERCERA, SE EXTRAE EL BIOXIDO DE CARBONO DEL GAS DESHIDRATADO; Y POR ULTIMO, SE CALIENTE AL GAS RESULTANTE Y SE DEVUELVE A LA ZONA DE REDUCCION, FORMANDO ASI UN CIRCUITO DE RECIRCULACION DE GAS REDUCTOR.
