Kemira Increases Capacity For Water Treatment Chemicals In China

July 14, 2021
Kemira invests to add capacity in water treatment chemicals to serve the growing Asia-Pacific market.

Kemira, maker of sustainable chemical offerings for water intensive industries, says it is increasing production capacity of water treatment chemicals in Yanzhou, China. The investment reflects another step forward in the execution of Kemira’s growth strategy and will serve the growing water treatment demand in China and the Asia-Pacific region, according to the company.

Kemira has started to build a new sodium hypochlorite production unit at Yanzhou site. It is expected to start commercial production in January 2022, according to the company. Sodium hypochlorite is a disinfectant used in the water treatment processes in the pulp and paper industry and process industry as well as in municipal water treatment. The product is also a key component in certain paper industry deposit control technologies, securing paper and board machine runnability.

Kemira is also finalizing the pre-engineering phase to increase the production of polyaluminum chloride (PAC) at Yanzhou. PAC is used as a coagulant in raw water and wastewater treatment processes and additionally as a fixative in the paper and board industry. The new unit is expected to be operational in March 2022, according to the company.

Kemira says PAC and sodium hypochlorite are manufactured in the new production units utilizing industrial side streams and recycled by-products as key raw materials. The production of PAC uses hydrochloric acid that is an organic by-product of Kemira’s own AKD wax production located in the same chemical park in Yanzhou, according to the company. The key raw material for sodium hypochlorite, caustic soda, comes from the side stream of a customer’s manufacturing process.
