Abstract

Se presenta un proceso para la producción de hierro reducido directo (DRI), con o sin carbono, usando hidrógeno, donde el hidrógeno es producido usando agua generada internamente del proceso. El proceso es caracterizado porque contiene ya sea uno o dos circuitos de gas, uno para afectar la reducción del oxido y otro para afectar la carburización del DRI. El circuito primario responsable de la reducción recircula el gas usado del horno de cuba en un circuito que incluye una etapa de desempolvado seco, una etapa de remoción de oxígeno para generar el hidrógeno, y una conexión con el horno de cuba para la reducción. En la ausencia de un segundo circuito, este circuito, en conjunto con la adición de gas natural, puede usarse para depositar carbono. Un circuito secundario de carburización instalado corriente abajo del horno de cuba puede controlar con mayor fineza la adición de carbono. Este circuito incluye un recipiente de reactor, una etapa de desempolvado, y una unidad de separación de gas.
