Public announcement regarding the 300,000 tons/year caprolactam project; it involves products such as polyamide thermoplastic elastomers. 2025-03-12 On February 27th, a draft environmental impact assessment report for Cangzhou Xuyang Chemical Co., Ltd.’s project to upgrade its 300,000 tons/year caprolactam production facility was made public for comments. The main production units in the existing plant include a caprolactam production facility with an annual capacity of 150,000 tons, a ** production facility with an annual capacity of 135,000 tons, another caprolactam production facility with an annual capacity of 300,000 tons, a ** production facility with an annual capacity of 270,000 tons, an ammonia synthesis facility with an annual capacity of 300,000 tons, a lignite-based hydrogen production unit with an output of 80,000 Nm3/h, a 35% hydrogen peroxide production facility with an annual capacity of 343,000 tons, 1 circulating fluidized bed boiler with a capacity of 75 t/h, 3 circulating fluidized bed boilers with a capacity of 220 t/h each, 2 cogeneration units with a capacity of 25 MW each, 1 lignite boiler with a capacity of 410 t/h, and a production line for polyamide thermoplastic elastomers with an annual output of 2,000 tons. In total, the plant’s capacity for caprolactam is 450,000 tons per year, for ammonium sulfate it is 690,000 tons per year, for polyamide thermoplastic elastomers it is 2,000 tons per year, for hydrogen peroxide it is 343,000 tons per year, for ** it is 405,000 tons per year, and for hydrogen gas it is 80,000 m3/h ； At the same time, light oil, X oil, fuel oil, alkoxy ketone oil, and heavy hydrocarbon oil are produced as by-products. The construction contents for this new project include: adding an aminoximation reaction system, a benzene stripping system, a neutralization and crystallization system, and a centrifuge to the existing lactam plant ； For the cyclohexanone plant, high-performance catalysts were installed for cyclohexanol dehydrogenation, and an additional hydrogen purification system was added ； At the same time, some system facilities, internal components of towers, heat exchangers, pumps, etc. are replaced, along with the addition of some utility and auxiliary facilities. Upon completion of the project, the caprolactam production capacity of the existing caprolactam plant increased from 300,000 tons per year to 360,000 tons per year; the cyclohexanone production capacity of the cyclohexanone plant rose from 270,000 tons per year to 330,000 tons per year. Meanwhile, the output of the by-product ammonium sulfate increased from 450,000 tons per year to 540,000 tons per year. Through Phase 1 and Phase 2, Cangzhou Xuyang has become the leading chemical enterprise in the caprolactam industry in terms of plant scale, with the highest output value, the largest production volume, the best product quality, and the lowest production costs; it is also an important industrial base for new nylon materials ； Through \"Cangzhou Xuyang + Dongming Xuyang\", Xuyang Group’s total capacity for caprolactam production has reached 750,000 tons per year, making it the world’s second-largest producer of caprolactam. Based on this, Cangzhou Xuyang has conducted further research into investment opportunities in new materials and fine chemicals. Taking advantage of the fact that caprolactam is an important monomer for producing nylon 6, and possesses excellent thermal stability, processability, mechanical strength, and chemical resistance, its applications span fibers (for household and industrial use, as well as for carpets), engineering plastics, and food packaging films. It is widely used in industries such as automobiles, ships, medical products, daily necessities, electronics, and electronic components, offering significant industrial advantages and market prospects. Xuyang plans to expand production of caprolactam and to implement projects related to the anionic polymerization of PA6 and other new material series, with the aim of establishing itself as the world’s leading producer of caprolactam. This will contribute to the group’s development of PA6, PA66, and other new material products based on caprolactam, helping it move faster toward its goal of becoming the most competitive global leader in caprolactam and nylon new materials, driven by technological innovation, with production capacities on the order of millions of tons and a focus on high-end materials.
