Chlorine dioxide is widely used in the pulp and paper industry as a bleaching agent. It is manufactured as a gas on site from sodium chlorate in a strongly acidic solution by reduction with sulphur dioxide, methanol, hydrochloric acid or alkali metal chloride. The chlorine dioxide gas is stripped from the solution with air and dissolved in water for storage and use.
The following methods cover all the necessary tests for a chlorine dioxide plant regardless of the manufacturing process used.
1. Generator Feed Solution Concentrations
2. Generator Liquor Concentrations
b) Acid and chloride
c) Chlorine dioxide and chlorine
3. Generator Gas Volume and Chlorine Dioxide Concentrations
4. Chlorine Dioxide Solution Concentrations
a) Chlorine dioxide and chlorine
b) Hydrochloric and sulphuric acid
