Abstract

a presente invenção refere-se aos fluxos de gases industriais, tais como fluxos de gases de combustível tratados para óxidos de nitrogênio, e outros contaminantes em depuradores secos ou semisecos. depois do fluxo de gás de combustível ter sido contatado com um sorvente, ozônio é misturado a jusante no fluxo de gás de combustível, dessa maneira oxidando os óxidos de nitrogênio e outros contaminantes. os contaminantes oxidados são contatados com o sorvente presente no fluxo de gás na altura ou volume remanescente do depurador a jusante de injeção de ozônio; e o sorvente é depois separado do fluxo de gás de combustível deixando o depurador seco ou semiseco.
