Abstract

UM PROCESSO PARA A PRODUçãO DE DIóXIDO DE CLORO. A presente invenção se refere a um processo para a produção contínua de dióxido de cloro, sob condições não-cristalizantes, em pelo menos dois vasos reacionais compreendendo as etapas de alimentar reacional clorato de metal alcalino, um ácido mineral e peróxido de hidrogênio para gerar um meio reacional mantido ácido no dito primeiro vaso reacional, reagir clorato de metal alcalino, peróxido de hidrogênio e ácido mineral no dito meio reacional para gerar dióxido de cloro e sal de metal alcalino do ácido mineral, remover o dióxido de cloro proveniente do dito meio reacional no dito primeiro vaso reacional como um gás, remover o meio reacional residual compreendendo ácido mineral, clorato de metal alcalino e sal de metal alcalino do ácido mineral proveniente do dito primeiro vaso reacional e alimentá-lo a um segundo vaso reacional, alimentar peróxido de hidrogênio ao meio reacional no dito segundo vaso reacional e manter este dito meio reacional a uma concentração de clorato de metal alcalino de aproximadamente 9 a aproximadamente 75 mmols/litro, reagir o clorato de metal alcalino, peróxido de hidrogênio e ácido mineral no dito meio reacional para produzir dióxido de cloro e sal de metal alcalino do ácido mineral, remover o dióxido de cloro proveniente do dito meio reacional no dito segundo vaso reacional como um gás, e remover o meio reacional residual compreendendo ácido mineral e sal de metal alcalino do ácido mineral proveniente do dito 30 segundo vaso reacional.
