Abstract

1.- Un proceso para producir continuamente dióxido de cloro comprende las etapas de:alimentar continuamente un reactor con ácido, un agente reductor y un clorato de metal álcali; hacer reaccionar el clorato de metal álcali con el ácido y el agente de reducción para formar un vapor de producto que contiene dióxido de cloro y la sal de metal álcali de ácido.; y, llevar dicho vapor de producto del reactor a una torre de absorción, en donde esta se conecta con un flujo de agua para formar una solución acuosa que contiene dióxido de cloro .2.- Un proceso como se reivindicó en la reivindicación 1, en donde la solución acuosa que contiene dióxido de cloro tiene una concentración de este de aproximadamente 4 a aproximadamente 12 g/l.3.- Un proceso como se reivindica en cualquiera de las reivindicaciones 1 a 2, en donde la concentración de CIO2 en la solución acuosa se mantiene independiente y substancialmente constante de el índice de producción de dióxido de cloro al ajustar el flujo de agua a la torre de absorción.4.- Un proceso como se reivindica en cualquiera de las reivindicaciones 1 a 3, en donde el gas no absorbido de la torre de absorción se retira mediante una tobera, creando una presión subatmosférica en el reactor y la torre de absorción.5.- Un proceso como se reivindica en cualquiera de las reivindicaciones 1 a 4, en donde el reactor se opera en una presión de aproximadamente 30 a aproximadamente 100 kPa.1. A process for continuously producing chlorine dioxide comprises the steps of: continuously feeding a reactor with acid, a reducing agent and an alkali metal chlorate; react the alkali metal chlorate with the acid and the reducing agent to form a product vapor containing chlorine dioxide and the alkali metal salt of acid .; and, taking said product vapor from the reactor to an absorption tower, where it is connected to a water flow to form an aqueous solution containing chlorine dioxide. 2. A process as claimed in claim 1, in wherein the aqueous solution containing chlorine dioxide has a concentration of this from about 4 to about 12 g / l.3.- A process as claimed in any one of claims 1 to 2, wherein the concentration of CIO2 in the solution The water remains independent and substantially constant of the index of production of chlorine dioxide by adjusting the flow of water to the absorption tower. 4. A process as claimed in any one of claims 1 to 3, wherein the gas does not absorbed from the absorption tower is removed by a nozzle, creating a subatmospheric pressure in the reactor and the absorption tower. 5. A process as claimed in any one of claims 1 to 4, in where the reactor is operated at a pressure of about 30 to about 100 kPa.
