Abstract
MÉTODO, DISPOSITIVO E USO DE DISPOSITIVO PARA REDUÇÃO DE MATERIAIS BRUTOS CONTENDO ÓXIDO DE FERRO. A invenção refere-se a um método de redução de estoques contendo óxido de ferro, onde um gás de redução é introduzido em uma unidade de redução de alta pressão (1). Na unidade de redução de alta pressão (1), o gás de redução é consumido pela redução dos estoques contendo óxido de ferro e é retirado como gás superior da unidade de redução de alta pressão (1). Pelo menos uma subparte do gás superior é misturada com um gás de alimentação como gás reciclado (15), onde o gás de redução é gerado pelo CO2 sendo separado da mistura de gás obtida a partir da adição de gás reciclado (15) para o gás de alimentação depois de uma ou mais etapas de compressão, e o gás reciclado (15) é adicionado ao gás de alimentação em pelo menos duas subcorrentes de gás reciclado que são separadas uma da outra com pressões de subcorrente de gás reciclado em várias distancias a partir da unidade de redução de alta pressão (1).
