Abstract

PROCESSO PARA A REMOçãO DE CONTAMINANTES A PARTIR DE CORRENTES DE GáS. A presente invenção provê processo para a inibição de níveis de óxidos de nitrogênio nas correntes de gás do processo a partir de intalações de produção e de regeneração de ácido sulfúrico. A corrente de gás do processo oriundo do boiler térmico de resíduo e do eliminador de névoa de candeia é posto em contato ozona que reagirá com áxidos de nitrogênio presentes no gás de combustão.
