Green chemistry: Circular economy for China 

The Graz based process engineering and technology company, Kanzler, is supplying the world’s largest plant for the climate-friendly production of epichlorohydrin to China. Thanks to its sophisticated design, the plant will enable massive savings in CO2 during production as well as reduce the amount of wastewater by a factor of ten.

From process design to training

Kanzler GmbH is supplying the complete package: The technology license, process design, key equipment and technical training necessary for construction of the 150,000 tonnes annual capacity epichlorohydrin plant, are all coming from this Graz based specialist. The plant is being built in the province of Shandong in China, together with a supporting glycerine plant and associated processing equipment for cleaning and recycling the brine produced during saponification and the glycerine process. Most of the epichlorohydrin produced will be used in the manufacture of resins.

More renewable raw materials, fewer greenhouse gases

The Kanzler concept combines green chemistry and the circular economy. As an example, 50 percent more renewable raw materials are used in the manufacturing process. This ensures internal reuse and recycling of waste streams. Compared to the conventional route using fossil resources, this leads to a tenfold reduction in the volume of wastewater and a significant reduction in CO2 emissions. Furthermore, the purified brine can be recycled directly and reused for production of caustic soda and chlorine without additional treatment.
