Pucheng Clean Energy Chemical Co., Ltd. is a large-scale, modern coal chemical enterprise jointly controlled by Shaanxi Coal Industry and Chemical Group and with equity participation from State Power Investment Corporation. It is designated as a key energy and chemical project under Shaanxi Province’s “12th Five-Year Plan” and a demonstration project supported by the State’s “Petroleum and Chemical Industry Layout Planning Scheme.” Focusing on the development pathway of “clean and efficient conversion, high-end and fine-value-added extension,” the company has entered a stage of large-scale, stable operation. Using coal as its primary feedstock, the company employs an integrated process chain—including coal gasification, gas purification, methanol synthesis, and olefin polymerization—to professionally produce methanol, polyethylene (PE), polypropylene (PP), and downstream high-value-added chemical products, which are widely applied in mid- to high-end sectors such as automotive components and medical packaging. Leveraging its independently integrated DMTO-II (second-generation industrial methanol-to-olefins) plant, the company operates a 1.8-million-ton-per-year methanol production facility and a 600,000-ton-per-year polyolefin production facility, and has constructed China’s largest single-train 2-million-ton-per-year methanol-to-olefins plant. Concurrently, it operates two 350-MW ultra-supercritical coal-fired power generation units and an integrated heat-and-power system, achieving cascaded energy utilization and optimized process integration. The company holds 12 authorized invention patents and 38 utility model patents; its core process package has passed technological achievement appraisal by the China Petroleum and Chemical Industry Federation, and its energy efficiency meets the advanced-level requirements stipulated in national standard GB 30180-2023. It has obtained certifications for ISO 9001, ISO 14001, and ISO 45001 management systems, and holds all legally mandated qualifications, including the Safety Production License for Hazardous Chemicals, the Pollutant Discharge Permit, the Water Withdrawal Permit, and the Special Equipment Use Registration Certificate. In 2022, it was recognized as a National Green Factory and included in Shaanxi Province’s Green Manufacturing List. Its business spans over ten provinces—including Shaanxi, Shanxi, Henan, Shandong, and Jiangsu—and it is deeply integrated into the construction of the Western Energy and Chemical Corridor, providing upstream and downstream industrial chain partners with high-quality polyolefin specialty materials, technical collaboration, green and low-carbon solutions, and stable, reliable supplies of chemical raw materials.
