Traditional industries "sprout new shoots"

In the production base of Henan Zhongyuan Chemical Co., Ltd., located in Tongbai County, Henan Province, production lines operate in an efficient and orderly manner. After evaporation, calcination, packaging and other links, bags of soda ash are loaded quickly, and the scene is busy.

Zhongyuan Chemical is an enterprise mainly engaged in the exploration and development of natural soda and the processing and sales of related derivative products. Since its establishment in 1998, the company has unswervingly taken the road of "green, circular and sustainable", continuously improved the level of resource exploitation and production and processing technology, and built an ecological industrial cluster dominated by natural soda chemical industry. to form a unique industrial chain of natural alkali circular economy. At present, the company has more than 20 invention patents in the field of natural soda mining and processing, and the process technology and economic benefit indicators continue to lead the industry. it was selected as the "list of leading enterprises for energy efficiency in key industries in 2023" jointly issued by the Ministry of Industry and Information Technology and other departments, and was rated as a national green factory.

Zhongyuan Chemical pays close attention to the goal of "double carbon" and promotes green production with technological innovation. In terms of resource mining technology, the company has successfully developed single well huff and puff solution production technology, well connectivity solution production technology, horizontal well solution production technology. Among them, the solution mining technology of horizontal well has been successfully used in the trial mining of deep and thin natural alkali deposits, and a breakthrough has been made in the mining of international ultra-deep and ultra-thin salt deposits. In terms of production and processing technology, the company carries out large-scale and energy-saving transformation of production equipment through "double semi-alkali" technology and "monohydrate alkali" technology, so that natural alkali production can achieve "low cost, high quality and no pollution".

Zhongyuan Chemical strives to build a green production system, form a number of circular economy industrial chains, and create a variety of green products.

Li Yongzhong, general manager of Zhongyuan Chemical, said that the company implements the "full chain" management of fuel coal, by optimizing the proportion of raw coal and adopting oxygen-rich combustion to improve coal burning efficiency, thermal efficiency and calorific value of raw coal, and greatly reduce coal consumption. Soda products are produced by using high quality brine, the alkaline mother liquor and carbon dioxide produced in soda production are recovered for the production of baking soda, and then the salty mother liquor produced in the process of baking soda is used to produce industrial mixed alkali products. as a result, the closed cycle and full utilization of resources can be realized.

"the development and utilization of new energy is an important way to achieve carbon emission reduction and green and low-carbon transformation and development. we speed up the construction of new energy projects, actively develop clean energy, do a good job in planning new energy projects such as wind power and photovoltaic, and further optimize energy structure. we will enhance the environmental carrying capacity of enterprises and create a new model of green and low-carbon development." Liu Erming, deputy general manager of Zhongyuan Chemical, said that in recent years, the company has carried out key R & D and construction projects, such as the research project on capture and resource utilization of carbon dioxide in industrial tail gas, the experimental project of wet decomposition and concentration of liquid dilatation completed, and the research and application project of wet decomposition and application of alkali solution based on sodium bicarbonate, to realize the connection between traditional industries and new industries, new economy and new technology, and to promote the "sprouting of old trees" in traditional industries.

At the same time, the company adheres to the green and low-carbon development plan, actively develops distributed wind power and distributed photovoltaic projects, creates a new power system of "integration of source network, load and storage", steadily reduces carbon emissions, and continues to strengthen the construction of green and low-carbon plants. At present, the company has completed the first phase of 6 MW distributed photovoltaic power generation project, with annual power generation of 6.5 million kilowatt hours, annual savings of 2000 tons of standard coal, carbon dioxide emission reduction of nearly 5000 tons, obvious energy saving and carbon reduction benefits.

The company also actively carries out new cooperation with the surrounding new energy operators to build a "green electricity hydrogen ammonia" industrial system, relying on the demonstration project of comprehensive utilization of natural alkali associated salt, expanding the landscape electricity hydrogen production and then producing synthetic ammonia industry. we will promote the local consumption and transformation of new energy.

"to become the benchmark enterprise of the world's natural soda circular economy is the goal of Zhongyuan Chemical. The company will strive to achieve green low-carbon and kinetic energy growth to promote each other, innovation to drive natural soda, green soda, compound fertilizer 'three major engines', and strive to achieve assets, production capacity, income 'triple'.
