Abstract

resumo patente de invenção: "método para tratar gases de refugo de usinas para a produção de gusa e/ou gás de síntese". a presente invenção refere-se a um método e a um sistema para tratar gases de refugo (4) de usinas (32, 33) para a produção de gusa e/ou gás de síntese, em que uma primeira subcorrente (51) do gás de refugo ou gás de síntese é submetida a uma conversão pelo menos parcial de co em co2 após a adição de água e/ou vapor de água (10), e o gás de refugo (4) ou gás de síntese é, então, submetido à captura de co2. para ser capaz de configurar uma razão de h2/co variável no gás de refugo ou gás de síntese, de acordo com a invenção, uma subcorrente adicional (52) do gás de refugo ou gás de síntese não é submetida a uma conversão de co em co2, mas é submetida à captura de co2 separadamente da primeira subcorrente (51).
