Abstract

La presente está relacionada con un proceso continuo para producir dioxido de cloro que comprende las etapas de: a) introducir en forma continua en un reactor un ácido, peroxido de hidrogeno y clorato de metal alcalino; b) hacer reaccionar en forma continua el clorato de metal alcalino con el ácido y el peroxido de hidrogeno para formar un flujo de producto que contenga dioxido de cloro, oxígeno y sal de metal alcalino del ácido, c) llevar en forma continua el flujo de producto del reactor a un eductor y mezclarlo con agua motriz introducida en el eductor y formar de esta manera un flujo de producto diluido; d) secar en forma continua oxígeno del flujo de producto diluido; e) retirar en forma continua parte del flujo de producto diluido, antes, durante o después de la etapa de sacar el oxígeno; f) agregar en forma continua agua a la parte no retirada del flujo de producto diluido para formar un flujo de reciclado; y g) llevar en forma continua el flujo de reciclado al eductor e introducirlo en el mismo como agua motriz. La presente está relacionada también con una unidad de Produccion para la produccion de una solucion acuosa que comprende dioxido de cloro.
