China's caustic soda equipment has reached the world's advanced level

On December 15, the 2022 National Caustic Soda Industry Technology Annual Conference was held
online.
Zhang Wenlei, chairman of the China Chlor-Alkali Industry Association, said that at present, the localization capacity of caustic soda production equipment has reached 100%, reaching the world's advanced level
.

Zhang Wenlei said that in recent years, China's caustic soda production technology and equipment have made continuous progress, energy and resource consumption has continued to decrease, and the comprehensive utilization rate of resources has been continuously improved
.
At present, caustic soda enterprises all adopt ion membrane electrolysis process and equipment, and the most advanced membrane electrode-distance sub-membrane electrolyzer has reached more than 90% in China, which is at the world-class level
.

Through industrial structure adjustment and in-depth implementation of energy conservation, emission reduction and upgrading, the comprehensive energy consumption of caustic soda products in China has continued to decline
.
With the continuous promotion and application of domestic ion membranes, the core auxiliary materials of ion membrane electrolysis technology, the localization capacity of caustic soda production equipment has reached 100%, and the equipment level ranks in the forefront
of the world's advanced level.
At present, the industry is increasing R&D and application promotion in energy conservation and carbon reduction, efficient application of hydrogen energy and electrolysis scheme for the utilization of high-salt wastewater, and constantly promoting the technological progress
of the caustic soda industry.
