ABSTRACT:
An improved process is provided for the production of chlorine dioxide and chlorine wherein an alkali metal chlorate and a strong acid selected from the group sulfuric acid, hydrochloric acid, phosphoric acid, and mixtures thereof are circulated and reacted in an integral forced circulation crystallizing reaction evaporator comprising in vertical disposition:
a. an upper crystallizing evaporation chamber having a substantially vertically disposed cylindrical partition which divides at least the lower portion of the reaction evaporation chamber into a first and second substantially concentric cylindrical sections;
B. a heat exchange chamber, and
C. a lower pump chamber, having a pump means disposed therein to provide forced circulation of fluids within the reaction evaporator.
An aqueous slurry of alkali metal salt of the strong acid is withdrawn from the lower portion of the pump chamber and chlorine dioxide, chlorine, and water vapor are withdrawn from the evaporation chamber.
