(referred to as “Yongrong Technology”), one of Fujian Province’s 100 key projects, managed to produce caprolactam products that satisfy **top-quality standards, marking a successful start to the pilot production in the chemical processing area of this integrated caprolactam project. The total investment for Yongrong Technology’s CPL Phase II project is 8 billion yuan, with the overall investment for the entire project amounting to 15 billion yuan. It was constructed with funding provided by Yongrong Group, one of China’s top 500 enterprises, as well as large state-owned enterprises at the provincial and municipal levels such as Fujian Investment and Development Group and Putian State Investment Group. The design work was carried out by various design firms including China Tianchen, China Aerospace Changzheng, PowerChina Jiangxi Institute, Liming Engineering Design Institute, and Sinopec Nanhua Institute. Dozens of construction companies participated in its building, including China Chemical Sanhua Construction, Sihua Construction, Liuhua Construction, Shiliuhua Construction, Jiangsu Yuanyou, Sichuan Power Construction, Longan, Zhejiang An, Shenzhen Haitian, and Hunan Xjin Cheng. The project utilizes industry-leading fourth-generation hydration and ammonoximation technologies, as well as a world-class digital intelligent safety and production control system to enable real-time visualization and digital management, thereby ensuring the production of high-quality caprolactam through advanced technology and equipment. Since its commencement in April 2021, the project has successfully and efficiently completed a series of tasks including design, procurement, civil construction, equipment installation, obtaining necessary permits, logistics transportation, project acceptance, commissioning, and production preparation. This ensured the successful start of trial production, with high-quality caprolactam being produced from the very first batch. Next, Yongrong Technology will fully integrate the strengths of state-owned enterprises such as CPL, the vitality of private enterprises, and the advantages of hybrid models. With a sense of urgency that time waits for no one and a sense of crisis that opportunities must not be missed, it will work tirelessly and with great determination, paying close attention to safety, ensuring precise operations, and optimizing performance. It aims to progress from starting up production to achieving stable production, and then to full capacity operation, so as to ensure the “stable, continuous, and high-quality” operation of CPL’s Phase II project. This will help the company achieve further success and make new contributions to the high-quality development of the local economy and society, as well as to the creation of a high-value industrial cluster for new functional materials worth hundreds of billions. The main production units of the second phase of Fujian Yongrong Technology’s caprolactam project include two sets of 200,000 tons/year olefin-based **units, as well as two sets of 200,000 tons/year caprolactam units. The supporting production facilities include a combined facility for coal-to-hydrogen production at 40,000 m3/h and coal-to-ammonia production at 300,000 tons per year, two hydrogen peroxide production facilities with a capacity of 200,000 tons per year (35%), and one sulfuric acid production facility with a capacity of 500,000 tons per year. Among them, hydrogen production and ammonia synthesis employ space furnace gasification. Project Overview: The caprolactam project of Yongrong Technology is located in the Shimen’ao Industrial Park, Dongzhuang Town, Xiuyu District, Putian City, Fujian Province. With a total investment of 15 billion yuan, the project is divided into two phases; the first phase, involving a capacity of 200,000 tons per year for caprolactam production, has already been completed and put into operation. The total investment for Yongrong Technology’s CPL Phase II project is 8 billion yuan, of which nearly 2 billion yuan is allocated to the hydrogen production and ammonia synthesis facilities. These facilities represent the most capital-intensive and take the longest time to build among the production units in this phase II project. They utilize the HT-L pressurized coal gasification technology developed independently by China’s Changzheng Chemical Engineering Co., Ltd.; this technology features environmental friendliness and economic reliability. Once completed, these facilities will be able to produce 640 million standard cubic meters of hydrogen per year. Fujian Yongrong Group is an outstanding domestic provider of new nylon materials. The company’s main product is caprolactam, which is primarily used in the fiber, engineering plastics, and food packaging film industries; it is also widely applied in fields such as aerospace, automotive manufacturing, medical products, daily necessities, and electronic components. The group has now established an integrated full industrial chain, aiming to become a new type of company that combines petrochemical engineering design, construction projects, and project management. The project is located in the Shimen’ao Industrial Park in Putian City, Fujian Province. Its main product is caprolactam, while the by-products include sulfuric acid and others. The completion of this project is of great significance for increasing China’s self-sufficiency in caprolactam, reducing imports, and raising the technical level and international competitiveness of China’s caprolactam industry.
