On June 13, the intermediate handover of the external piping work for this project, which aims at the relocation, upgrading, and transformation of Balin Petrochemical’s caprolactam production capacity to 600,000 tons per year, was carried out, laying a foundation for the complete completion of the project and its smooth commissioning. To date, 40 units of the project have been delivered, bringing the overall progress to 98.96%. At the handover ceremony for the external piping project of the Baling Petrochemical’s annual 600,000-ton caprolactam production chain relocation, upgrading, and transformation project, representatives from the six parties involved in the project’s construction – namely those responsible for production, design, construction, supervision, and quality control – jointly signed the overall project handover certificate. The external pipeline project for this facility was constructed by Sinopec Nanjing Engineering Company. It mainly includes – ◆ The construction of 17 pipe corridors, 805 axis points, a coverage area of 1.5 square kilometers, a length of 6.05 kilometers; there are 1,496 main framework columns and 3,758 main framework beams ； ◆ A total of 268 kilometers of process pipelines and utility pipelines were constructed, along with 11,000 tons of steel structures and 85,500 steel components; ◆ The anti-corrosion coverage area is approximately 245,000 square meters, while the insulation volume is about 8,900 cubic meters. The Baling Petrochemical caprolactam industry chain relocation, upgrading, and transformation project utilizes SE water-coal slurry gasification to produce 333,000 tons of liquid ammonia per year, 240,000 tons of hydrogen peroxide, 660,000 tons of sulfuric acid, 600,000 tons of caprolactam per year, and 150,000 tons of polycaprolactam. Project Overview According to the environmental impact assessment documents published by the Hunan Department of Ecology and Environment, the Baling Petrochemical caprolactam production project involves the construction of a facility with an annual capacity of 600,000 tons of caprolactam. It mainly includes air separation, coal gasification, hydrogen peroxide, **, ammonia oximation, caprolactam, polyamides, and sulfuric acid plants. The caprolactam production units are located in the central part of the plant area, divided into Line A and Line B. Line A and Line B are arranged parallel to each other. Process technology and equipment configuration: Air separation. The scale of the air separation unit is 90,000 m3/h of oxygen. Construction of Line A. Coal-to-hydrogen capacity: 192,000 m3/h (CO+H2). Gas is produced using water-coal slurry, with ammonia synthesis gas and hydrogen generated as by-products for supply to downstream industries. Construction of Line A. Synthetic ammonia is produced using nitrogen and hydrogen from coal-based hydrogen production units, with an annual output of 333,000 tons of liquid ammonia. Construction of Line A. Hydrogen peroxide is produced using the “slurry-bed palladium-catalyzed anthraquinone process”. Line A is designed to produce 120,000 tons of hydrogen peroxide per year. The scale and process of the B-line hydrogen peroxide facility are the same as those of the A-line. A total of 240,000 tons per year. Sulfur-based sulfuric acid production uses a \"two-turn two-absorption\" process, with an annual output of 660,000 tons of 104.5% sulfuric acid. Construction of Line A. Caprolactam is synthesized from raw materials such as benzene, hydrogen, hydrogen peroxide, and ammonia, through processes including esterification, amination (including rearrangement), ammonium sulfate recovery, and caprolactam purification. Line A is built to produce 300,000 tons of caprolactam per year. The scale and process of Line B caprolactam are basically the same as those of Line A. A new oxidation **unit** has been added to meet the demand for **, which previously had to be purchased, through in-house production. A total of 600,000 tons per year. Polyamides are produced using caprolactam as a raw material, with an annual output of 150,000 tons of polycaprolactam. Construction of Line A. The total investment in the relocation, upgrading, and transformation project of the caprolactam production chain at Baling Petrochemical amounts to 13.95 billion yuan. This project aims to establish a caprolactam production capacity of 600,000 tons per year, covering the entire production chain from coal-to-hydrogen production to polyamide manufacturing. The process equipment used in this project incorporates new technologies developed by Sinopec, including those related to hydrogen peroxide use. This project has been included by the headquarters in the list of key projects for 2020, and it is also listed as a key project in Hunan Province as well as one of the \"Five 100\" major industrial projects.
