<p>Process for the generation of chlorine dioxide by the essentially instantaneous reaction of a relatively concentrated aqueous solution of a metal chlorite and an oxidizing agent, preferably gaseous chlorine. The reaction is carried out in a generator having a mix and dwell premix chamber interconnected with a source of vacuum, preferably a venturi. The relatively concentrated aqueous metal chlorite solution and the oxidizing agent are allowed to mix and react in the premix chamber prior to any dilution as, for example, by water or other fluid flowing through the venturi eductor to deliver the generated chlorine dioxide to storage or utilization. When the oxidizing agent is chlorine, it is preferred for the chlorine stream to contain some bleed water in an amount below that which would significantly dilute the reactants and thereby have a quenching effect on the reaction. The presence of bleed water prevents a buildup of metal chloride on the chlorine inlet to the premix chamber.</p> |
