Chlorine Dioxide (ClO2) has been used as a bleaching chemical (for bleaching pulp) commercially for many years in Pulping Industries. Chlorine Dioxide production processes are based on the reduction of chlorate (using Cl-, CH3OH or SO2) in the presence of either sulphuric or hydrochloric acid where etching and corrosion occurs at the equipments used throughout the process.
