Abstract
The invention relates to a process for the production of chlorine dioxide comprising formation of an aqueous solution comprising chlorine dioxide, bringing at least part of the aqueous solution comprising chlorine dioxide to its end-application within an average residence time of less than 60 minutes, and maintaining part of the obtained aqueous solution comprising chlorine dioxide in at least one storage tank.
Claims15
A process for the production of chlorine dioxide by reducing chlorate ions in an aqueous reaction medium using methanol as a reducing agent, the process comprising formation of an aqueous solution comprising chlorine dioxide by withdrawing gas comprising chlorine dioxide from the aqueous reaction medium and absorbing chlorine dioxide from said gas into water, bringing at least part of the aqueous solution comprising chlorine dioxide to its end-application within an average residence time of less than 60 minutes, and maintaining part of the obtained aqueous solution comprising chlorine dioxide in at least one storage tank.
