The Yanshan Petrochemical Olefins Plant, formerly known as Qianjin Chemical Plant, began construction in August 1973; its production capacity of 300,000 tons per year of ethylene was established on May 1976. It served as a successful example of building large-scale imported manufacturing facilities in China and represented an important milestone in the modernization of China’s petrochemical industry, making significant contributions to the country’s economic development. With the reform and restructuring of Yanshan Petrochemical, the olefin plant carried out the first round of expansion and renovation of its ethylene production facility in March 1993 and the second round in March 2000 (to an output of 450,000 tons per year of ethylene), as well as a series of technical upgrades and the construction of additional facilities. These efforts expanded the production capacity, improved the technical level, and made the product portfolio more aligned with market demands, thereby significantly enhancing the company’s competitiveness. At present, the olefin plant has an ethylene production capacity of 800,000 tons per year, and is able to produce chemical products such as ethylene, propylene, butenes, ethylene glycol, ethylene oxide, isoprene, pure benzene, styrene, and polystyrene. Meanwhile, it also generates various petrochemical products as by-products, including hydrogen, toluene, and raffinate oil.
