Abstract
SE REFIERE A UN PROCESO PARA REDUCIR UN MATERIAL QUE CONTIENE OXIDO PARTICULADO POR EL METODO DE LECHO FLUIDIZADO, EN DONDE EL MATERIAL QUE CONTIENE OXIDO ES MANTENIDO EN UNA CAPA DE REMOLINO POR MEDIO DE UN GAS REDUCTOR QUE FLUYE DESDE LA PARTE INFERIOR HACIA LA SUPERIOR, SIENDO ASI REDUCIDO; CARACTERIZADO EN QUE LA VELOCIDAD EN TUBO LIBRE DEL GAS REDUCTOR, EXCLUSIVAMENTE POR ENCIMA DE LA CAPA DE REMOLINO, ES DISMINUIDA EN POR LO MENOS 25% PREFERIBLEMENTE 50%, EN LA SECCION TRANSVERSAL LIBRE PRESENTE POR ENCIMA DE LA CAPA DE REMOLINO, DE MANERA CONTINUA Y BAJO PREVENCION DE FORMACIONES DE REMOLINOS; SE REFIERE ADEMAS A UNA PLANTA PARA LLEVAR A CABO EL PROCESO ANTERIORMENTE DESCRITO, QUE COMPRENDE POR LO MENOS UN REACTOR DE REDUCCION DE CAPA DE REMOLINO, CARACTERIZADO EN QUE EL REACTOR DE CAPA DE REMOLINO COMPRENDE: A) UNA SECCION DE CAPA DE REMOLINO INFERIOR CILINDRICA QUE ACOMODA LA CAPA DE REMOLINO E INCLUYE UNA PARTE DE DISTRIBUCION DE GAS, UN DUCTO DE SUMINISTRO PARA EL GAS REDUCTOR Y UN DUCTO DE SUMINISTRO Y DESCARGA PARA EL MATERIAL QUE CONTIENE OXIDO; B) UNA SECCION AHUSADA QUE SE ENSANCHA CONICAMENTE HACIA ARRIBA CON UN ANGULO DE ELEVACION DE 8� A 10�; Y C) UNA SECCION CALMANTE, DE LA CUAL SALE UN DUCTO DE DESCARGA DE GAS REDUCTOR
