PROCESS AND APPARATUS FOR SUPPLYING ALKALI CHLORATE AND ACID TO A REACTOR FOR PRODUCING CHLORINE DIOXIDE

摘要

To produce a gaseous mixture of chlorine dioxide and chlorine, alkali chlorate solution is reacted with an acid, such as hydrochloric acid, in a reactor that comprises one or more reaction stages. The alkali chlorate solution and the acid are first passed jointly through a mixing chamber to form a mixed solution, which is supplied from the mixing chamber to the uppermost reaction stage of the reactor.
