<p>INTEGRATED SYSTEM FOR THE PRODUCTION OF CHLORINE DIOXIDE A cyclic integrated system for the production of chlorine dioxide utilizes a feed of only chlorine and water. The chlorine dioxide is recovered as an aqueous solution thereof and excess hydrogen is vented from the system. The chlorine dioxide is produced by reduction of sodium chlorate in aqueous acid solution having an acidity of about 0.05 to 1N and using hydrochloric acid as the reducing agent and acid source, the chlorine dioxide being removed in admixture with chlorine and steam evaporated from the reaction medium. The chlorine is separated from the chlorine dioxide and is used to form recycled hydrogen chloride. The sodium chloride formed in the chlorine dioxide-producing reaction is used to form sodium chlorate for recycle.</p> |
