On the 15th, the relocation, upgrading, transformation and development project of caprolactam industrial chain with an annual output of 600,000 tons in Baling Petrochemical Company of China Petrochemical Company was successfully completed, and it was successfully started once. This project adopts a new generation of green complete sets of caprolactam technology with independent intellectual property rights of China Petrochemical Company, which is the first time that this technology has been industrialized, marking the completion and commissioning of a single set of caprolactam R&D base with the largest capacity and leading technology in the world, and providing a new path for the green transformation and development of heavy chemical industry along the Yangtze River.
It provides a new path and model for the green transformation and development of heavy chemical industry along the Yangtze River. Caprolactam is an important organic chemical raw material, which is widely used in degradable films, medical devices, high-end clothing, automobile wheels and other fields. The total investment of this project is 15.35 billion yuan, covering an area of 2,650 mu. The project will relocate the caprolactam industrial chain of Baling Petrochemical, which is less than 1 km away from the Yangtze River and connected with the main urban area of Yueyang City, to Yueyang Green Chemical High-tech Zone, Hunan Province, which is 3.1 km away from the Yangtze River coastline. According to the idea of "safety and green, technology upgrading, first building and then dismantling, and doubling the scale", the project has newly built 58 units including coal gasification, caprolactam, polyamide, synthetic ammonia, hydrogen peroxide and cyclohexanone, covering the whole industrial chain from coal to polyamide, and the annual production capacity of caprolactam has increased from 300,000 tons to 600,000 tons. The project promotes the transformation and upgrading of traditional petrochemical industry to high-end, intelligent, green and integrated through upgrading industrial chain, extending product chain and upgrading value chain.
With independent intellectual property rights, it provides important technical support for the transformation, upgrading and development of caprolactam industry chain in China. The project adopts the green complete set of new technologies of caprolactam, which won the China Industrial Award and the first prize of national technological invention. Among them, esterification hydrogenation to cyclohexanone and slurry bed anthraquinone to hydrogen peroxide are the "Ten Dragons" scientific and technological key projects of China Petrochemical Company. The esterification hydrogenation to cyclohexanone plant is the first industrialized plant in the world, which adopts a brand-new reaction principle and subverts the traditional technological route. It has the advantages of high carbon yield, less discharge of "three wastes", cleanliness and high efficiency, and provides important technical support for the transformation and development of the industrial chain. The technology of preparing hydrogen peroxide from anthraquinone in slurry bed and the technology of preparing cyclohexanone oxime from cyclohexanone oxime were successfully enlarged and applied for the first time, and the safety factor of the new technology of hydrogen peroxide was effectively improved. The coal gasification plant is the first one in China Petrochemical Company to adopt the third generation domestic coal water slurry water wall gasification technology. The project was built in accordance with the standard of "5G Smart Factory", with the localization rate of equipment of 99.9% and the central control system of the project all localized.
Over the years, China Petrochemical has been committed to leading the way of caprolactam innovation in China. As the largest producer and supplier of caprolactam in China, China Petrochemical has always adhered to innovation-driven development, continuously improved the production technology and product quality of caprolactam, and made important contributions to the transformation, upgrading and green development of caprolactam industry in China. In addition to independent research and development of caprolactam production process, the company also continuously develops new applications of caprolactam, such as biodegradable plastics, high-performance fibers, medical materials, etc., which expands the market demand and social value of caprolactam. The caprolactam products produced by the company have passed ISO 9001, ISO 14001 and other certifications, enjoying a good market reputation.
