The main production facilities for China Chemical’s project to manufacture 50,000 tons per year of ultra-high molecular weight polyethylene resin have been basically completed! Recently, visiting the construction site of the 50,000-ton-per-year ultra-high molecular weight polyethylene resin production facility in Yulin High-Tech Zone, it was observed that the main structures of various production units had been largely completed; workers were moving around among these equipment, carefully handling the details of the project in various areas. This project utilizes production technology for ultra-high molecular weight polyethylene resin based on China Chemical’s own intellectual property rights; ultra-high molecular weight polyethylene resin is produced through a batch slurry polymerization process. Once completed, the project will be able to supply 50,000 tons of high-quality ultra-high molecular weight polyethylene resin products to the market each year. Construction on this project began in October 2023, with commissioning expected in August this year. The project was chosen to be located in Yulin because the ethylene and hydrogen produced in the high-tech park, along with the hexane purchased from the market, all serve as raw materials for the polyethylene resin production. Project Name: Project for Annual Production of 50,000 Tons of Ultra-High Molecular Weight Polyethylene Resin
Constructor: Sinochem Western New Materials Co., Ltd.
Construction Scale: This project aims for an annual production of 50,000 tons of ultra-high molecular weight polyethylene resin; it involves the construction of two production units, with capacities of 20,000 tons and 30,000 tons respectively. Nature of construction: New construction. Location: The project is situated in the Heng Industrial Zone, Yuyang District, Yulin City, Shaanxi Province. Investment amount: 830 million yuan, to be fully funded by the enterprise itself. The environmental protection investment for this project is 35.6894 million yuan, accounting for approximately 4.3% of the total project investment. Project components: The main construction elements of this project include the main workshop, production facilities, storage areas, waste gas treatment systems, as well as supporting utility facilities (central laboratory, administrative building, central control room), etc. Process technology selection: The ultra-high molecular weight polyethylene process technology developed by Sinochem Research Institute is utilized. This institute now possesses a pilot-scale production process kit for high-end ultra-high molecular weight polyethylene resins, for which it holds complete independent intellectual property rights, offering good prospects for industrialization. In recent years, the China Chemical Research Institute has also independently developed proprietary technology for producing ultra-high molecular weight polyethylene of different grades by adjusting operating conditions. The research institute has developed an efficient catalyst focused on controlling the molecular weight of polymers, enabling the molecular weight distribution of the products to meet the desired targets. By utilizing a batch-type slurry polymerization process along with a uniquely designed stirrer of its own invention, shear force is increased; external circulation for heat removal helps to significantly reduce issues such as material buildup in the reactor. As a result, the variation between batches is as low as 0.02 g/cm³. This catalyst features a mature and advanced production technology, ensures stable and reliable operation, requires mild operating conditions, has low production costs, enables compliant discharge of waste materials, and guarantees consistent product quality, thus meeting the requirements of industrial applications.
