Abstract

INJEçãO DE DUTO ALVEJADO PARA CONTROLE DE S0~ 3~. Emissões de NO~ x~ e SO~ 3~ de combustão de um combustível carbonáceo contendo enxofre são reduzidas simultaneamente. Os gases de combustão compreendendo NO~ x~ e SO~ 2~ são misturados com um agente de controle de NO~ x~ nos gases de combustão a um ponto a montante de um catalisador de reação catalítica seletiva para redução de NO~ x~. Seguindo-se um catalisador de SCR ou outro equipamento que possa oxidar SO2 em SO~ 3~ e antes do contato com um aquecedor de ar para aquecimento do ar de combustão que chega, hidróxído de magnésio é introduzido em quantidades e tamanhos de goticula e concentrações eficazes para formar nano partículas no efluente e reduzir SO~ 3~ causado por oxidação de SO~ 2~ no catalisador. Di- nâmica computacional dos fluidos é empregada para determinar taxas de fluxo e selecionar taxas de introdução de reagente, localização(ões) de introdução de reagente, concentração de reagente, tamanho de gotícula de reagente e/ou momento do reagente.
