Caustic soda industry has outstanding performance in energy saving and carbon reduction

During the National Energy Conservation Publicity Week on June 16, the reporter learned from the national caustic soda energy conservation and carbon reduction work publicity and implementation meeting organized online by the China Chlor-Alkali Industry Association that at present, China's chlor-alkali industry has undergone industrial restructuring and in-depth implementation of energy conservation and emission reduction upgrades.
The comprehensive energy consumption per unit product of caustic soda continued to decline, the equipment level was at the forefront of the world's advanced level, and a large number of key enterprises performed well
.

Zhang Wenlei, chairman of the China Chlor-Alkali Industry Association, pointed out in his speech that in recent years, China's caustic soda production technology and equipment have made continuous progress, energy and resource consumption have continued to decrease, and comprehensive utilization of resources has continued to improve
.
At present, the company has all adopted the ionic membrane electrolysis process and equipment, and the transformation of the membrane pole distance has completed more than 90%, which is at the world-class level
.
With the maturation of localized ion membrane products and the continuous expansion of applications, the localization capacity of production equipment in the chlor-alkali industry has reached 100%, and the level of equipment ranks in the forefront of the world's advanced level
.

Gao Zijian, general manager of Qingdao Gulf Chemical Co.
, Ltd.
, and Dong Hongbo, vice president of Binhua Group Co.
, Ltd.
, shared their experience in energy saving and carbon reduction.
Significant results have been achieved in training and improving the skills of employees
.
Specific measures include implementing technological transformation and upgrading, optimizing resource utilization, realizing full utilization of waste heat and pressure of caustic soda plant, supporting advanced production control system and rectification and transformation system, introducing modern information management platforms such as SAP, ERP, OA, CBS, etc.
, to enhance core In order to improve the competitiveness of employees, we will carry out innovation and efficiency activities for all employees, rationalization suggestions, emergency drills, technical transformation and technical measures, etc.
, to enhance the enthusiasm of employees, tap energy-saving potential at multiple levels, and achieve innovation and efficiency, energy conservation and emission reduction
.

Focusing on caustic soda equipment innovation and material research and development innovation, Zhang Jian, chairman of Chongqing Bozhang Intelligent Equipment Co.
, Ltd.
, said that the implementation of four-effect evaporation and energy-saving transformation and upgrading of caustic soda enterprises with high-concentration caustic soda and solid flake soda as the main products can effectively save steam consumption, Reduce carbon emissions; the application of intelligent flake machine, ion-membrane caustic soda molten salt falling film evaporation and concentration integration technology will also play an important role in promoting energy saving and carbon reduction in the caustic soda industry and achieving green development
.

Liu Yancai, general manager of Shaanxi Beiyuan Chemical Group Co.
, Ltd.
and head of the caustic soda expert group of China Chlor-Alkali Industry Association, shared the company's experience in energy-saving technological transformation and energy management system construction
.
He pointed out that caustic soda enterprises should increase scientific and technological investment in low-carbon product development, low-carbon technology application, green hydrogen resource development and other fields, and rely on industrial integration to build a new type of competition integrating clean energy + energy storage + chemical industry + hydrogen energy + zero carbon Power model, reduce life cycle carbon emissions, and provide new impetus for the high-quality development of enterprises
.

It is reported that under the background of "double carbon", the chlor-alkali industry is strengthening green and low-carbon technology research, accelerating the transformation of innovative achievements, and helping to make new progress in energy conservation and carbon reduction
.
The utilization of ionic membrane caustic soda equipment to carry out industrial waste salt resource utilization, efficient development and utilization of chlor-alkali hydrogen energy, and research on electrocatalytic processes and electrocatalysts in the chlor-alkali industry are becoming key topics for energy conservation and carbon reduction in the industry
