Chlorine dioxide is an extremely common bleaching agent in the pulp and paper world. Since ClO2 becomes explosive when exposed to light or heat, it has to be produced on site at the paper mill. The on-site generator produces ClO2 from sodium chlorite or sodium chlorate, and the gas is then sent to a water absorption tower to create the bleaching agent solution.
The cost of this process can be dramatically reduced if the generator is operated to produce the correct amount of ClO2 for the bleaching agent without overkill and if the bleaching agent verifiably contains the right ClO2 concentration for proper bleaching. Additionally, the tail gas from the production process needs to be monitored to ensure that the facility is not releasing chlorine dioxide into the atmosphere.
The OMA system provides continuous online measurement of ClO2 concentration at each of these sampling points. This solid state, fast-response instrument provides a more elegant and more powerful solution than traditional analyzers for this specific application. With robust multiplexing capabilities, a single OMA unit can be configured to monitor all of these sampling points.
