Chlorine dioxide – gas
- Down to 1ppm (2.3 mg.Nm-3) chlorine dioxide in the gas phase
- Real time continuous measurement
- Optimize generator & gas scrubber performance
- Emission monitoring to ensure environmental regulations are met
Chlorine dioxide (ClO2) is used primarily as a bleaching agent in the pulp and paper industry for elemental chlorine free (ECF) bleaching. Chlorine dioxide has a strong UV absorption and is accurately and continuously measured in all liquid and gas streams using a Kemtrak chlorine dioxide analyzer.
The Kemtrak chlorine dioxide analyzer is used to optimize the reaction efficiency of ClO2 generation, improve the control of vent-gas scrubbers to reduce emissions into the atmosphere and for monitoring the final concentration of chlorine dioxide product sent to the bleaching plant.
Chlorine dioxide is an aggressive chemical substance – all wetted parts of the Kemtrak DCP007 flow cell are manufactured from corrosion resistant materials such as titanium and sapphire.
