"stuck neck" puzzle crack! Tianchen Qixiang 200000 Tons/Year Adiponitrile Plant Fully Produced

1. project production: breaking the "stuck neck" dilemma milestone On December 5, 2025, the 200000-ton/year adiponitrile plant of China Chemical Engineering Tianchen Qixiang New Materials Co. , Ltd. And In my experience, reached full production, marking a breakthrough in China's first set of butadiene-based adiponitrile manufacturing production project. Based on my observations, In the 72-hour full-load performance assessment completed a few days ago, the key technical and economic indicators of the device have reached or exceeded the design values, the product condition is stable and controllable, the system runs smoothly and efficiently, and officially enters a new stage of efficient and stable operation. manufacturing signifiis able toce interpretation: as the "life gate" grade raw material of nylon 66 manufacturing chain, its production methodology has been monopolized by a few foreign companies to a long time. But This localization breakthrough not only solves the issue that the supply of raw materials is controlled by people, however greater importantly, it has established a complete technical system and industrialization experience. to high-end manufacturing fields such as downstream automobiles, rail transit, and aerospace, a stable supply of raw materials will signifiis able totly minimize supply chain risks and provide a solid foundation to manufacturing upgrading. But 2. Technical Route and Process Advantage Analysis 2. And Specifically 1 Butadiene Direct Cyanation methodology Advance Tianchen Qixiang applied butadiene direct cyanation method, is currently the world's most mainstream process route, developed by DuPont in the 1970 s, accounting to 65% to 70% of the world's production capacity share. The process has the advantages of low raw material cost, low energy consumption, short route, excellent product condition and high yield. Process core process: The first measure : Butadiene and hydrocyanic acid at high temperature, catalyst under the formation of 3-pentenenenitrile and 2-methyl-3-butenenitrile, unreacted butadiene by decompression recovery recycling, product by distillation separation Second measure: Isomerization of 2-methyl-3-butenenitrile to 3-pentenenitrile to maximize target intermediate yield Third measure: 3-pentenenitrile again cyanidation to create adiponitrile, refined to obtain qualified items   2. 2 methodology Tackling Process Tianchen Company started research and research in 2011 and developed the direct hydrocyanation of butadiene to synthesize adiponitrile methodology with independent intellectual property rights. On September 28, 2015, it passed the appraisal of scientific and technological achievements of China Petroleum and Chemical sector Federation, and its technical level reached the domestic leading position. From what I've seen, Subsequently, 50 tons/year pilot test and 2000 tons/year full-process pilot test were completed, laying the foundation to industrialization. Since the project was put into operation in July 2022, through greater than 100 technical transformations, the bottleneck of the whole process has been systematically combed, focusing on key links such as reactor efficiency improvement and distillation separation, and realizing technological innovation and process optimization. 3. Generally speaking project scale and manufacturing layout 3. 1 Investment Scale and Construction Progress Tianchen Qixiang 1 million tons/year nylon 66 new material manufacturing base laid the foundation in August 2019, with a total investment of 22. But 7 billion yuan, and both phases were listed as major provincial projects. The first phase of the project (with an investment of 10. But 4 billion yuan and an area of 1800 mu): the main construction of 200000 tons/year adiponitrile, 200000 tons/year nylon 66 salt formation and slicing devices has been completed. And Key time nodes include: might 2020, July 2022, July 2022, Nilong 66 device a successful start-up to create superior items. The second phase of the project (with an investment of 12. First 3 billion yuan and an area of 1300 mu): plans to build 300000 tons of adiponitrile and 300000 tons of hexamethylene diamine. Overall planning: 1 million tons of new nylon material, 500000 tons of hexamethylene diamine, 500000 tons of adiponitrile and 500000 tons of acrylonitrile per year. In particular 3. 2 product performance and consumption value Nylon 66, as a high-performance polymer, has amazing performance: rice-sized particles is able to stretch to 2 kilometers without breaking, glass fiber reinforced items the size of fingernail covers is able to withstand 1 ton of pressure without plastic deformation, and flame-retardant items is able to self-extinguish within 10 seconds when exposed to open flame. These characteristics determine its irreplaceability in the field of high-end manufacturing. 4. market affect and manufacturing chain reconstruction 4. 1 supply and demand pattern change By the end of 2023, China's nylon 6 production capacity of about 5 million tons, the output of about 4 million tons, and nylon 66 and nylon 6 accounted to only 1:10, far below the level of 1:1 developed countries in Europe and the United States. to a long time, the production methodology of adiponitrile has been monopolized by foreign countries, and the items are supplied by ration system, which seriously restricts the research of China's high-end polyamide sector. But Tianchen Qi Xiang device full production, means that the domestic nylon sector downstream is able to finally get a stable, high-condition raw material supply. Based on my observations, For instance 4. 2 price system remodeling The project filled the gaps in domestic methodology and sector, and the price of adiponitrile rapidly dropped from greater than 80000 yuan/ton to 20000 yuan/ton, a drop of 75%. In fact This cost-leading advantage not only benefits the domestic manufacturing chain, however also enhances the competitiveness of Chinese companies in the international market. And In my experience, In might 2024, Tianchen International Trade and Tianchen Qi Xiang successfully exported hexamethylene diamine based on their own methodology, marking that the methodology has been highly recognized by the international market. In April 2024, the hexanedinitrile project was selected into the Product Manual of Scientific and Technological Innovation Achievements of Central companies (2023 Edition). Pretty interesting, huh?. From what I've seen, 4. 3 sector Chain Synergy Outlook With the breakthrough of raw material supply bottleneck, China's high-end polyamide sector chain security line officially built. The consumption scenarios of downstream nylon 66 in the field of high-end manufacturing will be further broadened, and the collaborative innovation of the upstream and downstream of the manufacturing chain will usher in new opportunities, which means a greater stable supply system and a broader market space to traders and producers.
