Abstract

PROCESSO PARA PRODUçãO DE DIóXIDO DE CLORO A presente invenção refere-se a um processo para produção continua de dióxido de cloro, compreendendo as etapas de: alimentar um ácido, um agente redutor e um clorato de metal alcalino a um reator, reagir o clorato de metal alcalino com o ácido e o agente redutor para formar uma corrente de produto contendo dióxido de cloro e o sal de metal alcalino do ácido; e, trazer a dita corrente de produto do reator para uma torre de absorção, onde a mesma é contatada com um fluxo de água para formar uma solução aquosa contendo dióxido de cloro. A invenção também se refere a uma instalação para produzir dióxido de cloro. A invenção refere-se ainda a uma nova solução aquosa compreendendo dióxido de cloro.
