Abstract
La presente invención se refiere a un procedimiento de preparación de clorato de metal alcalino, por electrólisis en una célula de membrana (3), de un anolito que comprende una solución de cloruro de metal alcalino y de un catolito que comprende una solución de hidróxido de metal alcalino, siendo la solución de cloruro de metal alcalino previamente purificada por la sucesión de etapas siguientes: -electrólisis en la célula de tipo 'cloro-sosa' (1) de una salmuera de cloruro de metal alcalino para formar por una parte cloro gaseoso, y por otra parte una solución concentrada de hidróxido de metal alcalino, - transferencia del cloro gaseoso y de la solución de hidróxido de metal alcalino producidos, a una columna de neutralización (2), para hacerlos reaccionar el uno con el otro, y - recuperación de la solución salina así obtenida, para su empleo como anolito en la célula de membrana (3). La presente invención se refiere también a un dispositivo de realización de este procedimiento y un dispositivo de purificación de una salmuera de cloruro de metal alcalino.The present invention relates to a process for the preparation of alkali metal chlorate, by electrolysis in a membrane cell (3), of an anolyte comprising a solution of alkali metal chloride and of a catholyte comprising a solution of hydroxide of alkali metal, the alkali metal chloride solution being previously purified by the succession of the following steps: -electrolysis in the cell of the 'chlorine-soda' type (1) of an alkali metal chloride brine to form chlorine gas on the one hand , and on the other hand a concentrated solution of alkali metal hydroxide, - transfer of the chlorine gas and the alkali metal hydroxide solution produced, to a neutralization column (2), to make them react with each other, and - recovery of the saline solution thus obtained, for use as an anolyte in the membrane cell (3). The present invention also relates to a device for carrying out this process and a device for purifying an alkali metal chloride brine.
