More than 100 years of chlorate manufacturing experience has helped us become the leading global provider of sodium chlorate. We leverage this experience to improve our production efficiency and process sustainability.

Overview - production process

Sodium chlorate is produced by the electrolysis of brine (sodium chloride and water), according to the following equation: NaCl + 3 H2O + 6 e- → NaClO3 + 3 H2
This energy-intensive, multistage process is run in closed loop plants from which emissions are kept to a minimum. This requires maintaining good chemical balances and running with precise control – the process is highly dependent on pH and temperature.

Environmental and sustainability factors have focused our attention on reducing energy requirements for sodium chlorate production with the objective of reducing our carbon footprint. Whenever possible, we locate our manufacturing facilities where renewable energy sources are available.
Thanks to advancements in our proprietary electrode design, we have been able to minimize the electrical power consumption of this process, while maintaining product quality. At our Chemical Islands we place our manufacturing facilities close to customer and chlorine dioxide production locations, where we can take advantage of available bio-based energy to produce chlorate.
We have also achieved reductions in waste and emissions from our process in recent years; our sodium chlorate process does not have emission to water. And the byproducts (hydrogen and heat) are used in a variety of other applications.
Our experts are continuously exploring opportunities for sodium chlorate production efficiency and sustainability improvements through lab analysis, pilot plants, and full-scale plant optimization. Learn more about our capabilities within process and application RD&I.
