Pulp & Paper

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 DCP007 LED process photmeter.

The Kemtrak DCP007 LED process photmeter 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.
