Abstract

Un proceso de reducción directa para producir hierro reducido directo (DRI) en un reactor de reducción que tiene una zona de reducción para reducir partículas contentivas de óxidos de hierro, tales como pastillas de mineral de hierro, a DRI mediante la reacción de dichos óxidos de hierro con un gas reductor a elevada temperatura y una zona de enfriamiento para bajar la temperatura del DRI producido en dicha zona de reducción, donde se circula un torrente de gas de enfriamiento, usualmente gas natural, a través de dicha zona de enfriamiento, se retira una porción de dicho gas de enfriamiento de la zona de enfriamiento, se enfría y limpia en un enfriador de gas y se recicla una porción del gas enfriado hacia dicha zona de reducción por medio de un eyector que utiliza alimentación de reabastecimiento de gas natural a alta presión como el fluido motriz del eyector. La utilización de un eyector para reciclar el gas de enfriamiento en vez de utilizar un compresor mecánico proporciona ahorros significativos en electricidad y en costos de capital, operacional y de mantenimiento. Una planta de reducción directa que tenga una zona de enfriamiento DRI que utilice por lo menos un eyector en el reciclaje de por lo menos una porción del gas de enfriamiento hacia la zona de enfriamiento.
