! Yangzi Petrochemical invests over 3 billion yuan in a new special long-chain nylon industry chain project 2025-08-05 Recently, the first public announcement regarding the environmental impact assessment of Yangzi Petrochemical’s long-chain nylon industry chain project was made. Name and Overview of the Construction Project: Project Name: Yangzi Petrochemical Long-Chain Nylon Industry Chain Project ； Project nature: New construction ； Construction location: Southeast side of the Sinopec Yangzi Petrochemical Co., Ltd. campus ； Total investment: 3,043.28 million yuan (excluding VAT) ； Construction scale and scope: Sinopec Yangzi Petrochemical Co., Ltd. plans to allocate additional land on the southeast side of the existing plant site to build a \"50,000 tons per year YDA industrial production facility and a 18,500 tons per year special nylon polymerization facility.\" The total investment for this project is 3,043,280,000 yuan (excluding value-added tax), with a total land area of 157,980 square meters. Yangzi Co., Ltd. invested in the construction of a 1,000-ton capacity YDA flexible pilot plant project. This project received approval for its environmental impact assessment in August 2018 (document number: Ning Huan Jian 9), was completed in December 2019, and passed the independent environmental protection inspection upon completion in July 2020. At present, the original 1,000-ton-class YDA flexible pilot project has completed the pilot tests using the batch process successfully, and it has been verified through application trials by the manufacturer that its products meet the requirements for market use. To ensure the continuous and stable operation of this industrialized facility, control production risks, and maintain operational efficiency, Yangzi Co., Ltd. plans to carry out further modifications to the continuous process of the YDA flexible pilot plant, building on the results of the batch-process pilot trials. A total investment of 46.0865 million yuan was allocated to this project, which involved carrying out continuous-process modifications to Unit A of the original thousand-ton-scale YDA flexible pilot plant ； After the modification, only a pilot test for continuous production in Unit A was carried out, while the remaining production units of the original plant were shut down. Through the implementation of this project, pilot-scale verification support can be provided for the subsequent construction of an industrial-scale facility for long-chain nylon monomers at Yangzi Petrochemical, thereby further verifying the feasibility of applying Yangzi Petrochemical’s long-chain technology to short-chain compounds. The continuous process renovation project for Unit A of the thousand-ton-class YDA flexible pilot plant project commenced on November 1, 2022, and the project was completed and commissioned on August 22, 2023.
