Abstract

"PROCESSO PARA A PRODUçãO DE DIóXIDO DE CLORO". A presente invenção se refere a um processo para a produção continuamente de dióxido de cloro. Em concordância com a presente invenção, o referido processo está caracterizado pelo fato de que compreende as etapas de: diluir ácido sulfúrico de uma concentração inicial excedendo cerca de 90 % em peso com água para uma concentração a partir de cerca de 60 % em peso até de cerca de 90 % em peso; trazer o ácido sulfúrico diluído para uma temperatura abaixo de cerca de 100 <198>C; alimentar para um reator (5) o ácido sulfúrico diluído possuindo uma temperatura abaixo de cerca de 100 <198>C através de um primeiro bocal de alimentação (1); alimentar para o referido reator (5) uma solução aquosa compreendendo clorato de metal alcalino e peróxido de hidrogênio através de um segundo bocal de alimentação (2), em que o referido primeiro bocal de alimentação (1) e o referido segundo bocal de alimentação (2) estão opostos um para o outro e direcionados um contra o outro; reagir o clorato de metal alcalino com o ácido mineral e com o peróxido de hidrogênio para formar uma corrente de produto contendo dióxido de cloro; e extrair a corrente de produto a partir do reator (5). A presente invenção adicionalmente se refere a um aparelho utilizável para a produção continuamente de dióxido de cloro.
