Abstract

a presente invenção trata de processos e sistemas metalúrgicos para atomização de gás de escória derretida e/ou metais derretidos de uma fornalha metalúrgica são integrados a processos e equipamentos de manipulação de gás de combustão, de modo que os gases de combustão sejam alimentados à instalação de atomização de gás para atomizar a escória derretida e/ou metal derretido. o uso de subprodutos de gases de combustão para atomizar escória derretida e/ou metais derretidos provê diversos benefícios, incluindo a eliminação de equipamentos de manipulação e tratamento de gás de combustão, centralização e promoção de calor por meio da atomização para aprimorar a recuperação de calor, prevenção de oxidação de produtos granulares de atomização e redução de emissões de co2. um processo para preparar um produto granular compreende: alimentação de um material derretido e um subproduto de gás de combustão a um aparelho de dispersão; e contato do gás com o material derretido no aparelho de dispersão, pelo que o material derretido é disperso e solidificado pelo contato com o gás para formar o produto granular.
