Abstract

método para limpar um fluxo de gás carregado com poeira. a presente invenção refere-se a um método para limpar um fluxo de gás constituído de gás recolhido do topo do alto-forno e/ou efluente gasoso e/ou gás de exportação de uma usina de redução direta ou uma usina de redução por fusão, que é carregado com poeira e/ou finos sólidos de particulado. o fluxo de gás é submetido a uma limpeza a seco por meio de pelo menos um filtro a seco, em que as poeiras e/ou matérias-primas de particulado fino são separadas do fluxo de gás. o fluxo de gás limpo é fornecido para um dispositivo de separação de co~ 2~, em que o co~ 2~é separado, formando um gás d eproduto que é substancialmente livre de água e de co~ 2~ e é usado para reverter o fluxo do filtro a seco.
