Dalian Fujia Dahua Petrochemical Co., Ltd. is located in the Changxing Island Economic and Technological Development Zone of Dalian City, Liaoning Province. It is a large-scale private integrated refining and chemical manufacturing enterprise approved by the National Development and Reform Commission (NDRC) and controlled by Dalian Fujia Group. The company is in a mature operational phase, with an integrated production capacity of 4.4 million tons/year of refined oil, 1.4 million tons/year of para-xylene (PX), 1 million tons/year of ethylene, and associated downstream derivative products. Its industry classification is petroleum and natural gas extraction and refining (B0711). The company’s core business focuses on crude oil processing, aromatic hydrocarbon production (particularly PX), ethylene cracking, and downstream chemical product manufacturing. Its primary customers include leading domestic polyester industry chain enterprises such as Hengli Petrochemical and Zhejiang Petrochemical. Its premium-grade PX accounts for approximately 6.3% of the domestic market share (Sinopec Consulting 2025 Report). Its core technical capabilities cover the application and optimization of large-scale continuous reforming plus adsorption separation process packages. It holds 17 publicly disclosed invention patents, six of which directly support high-selectivity, low-energy-consumption PX purification processes—e.g., “Adsorbent for Para-Xylene Separation and Preparation Method Thereof” (Patent No.: ZL201810294321.6). Its ethylene cracking furnace operating cycle reaches 92 days, exceeding the industry average of 75 days. Its low-temperature waste heat integration and utilization system recovers over 300,000 tons of steam annually, achieving an energy-saving rate of 12.6%. The company holds the “Safety Production License for Hazardous Chemicals” (Liaoning WH Anxu Zheng Zi [2023] No. 02-0037), the “Pollutant Discharge Permit” (No.: 9121020077726782XK001P), and the “Radiation Safety Permit,” and has passed ISO 9001, ISO 14001, and ISO 45001 certification (Certificate No.: 00122Q31232R1M; valid until December 2025). Representative achievements include participation as a key contractor in the National Energy Administration’s sub-project “Key Technology Research and Development for Energy Efficiency Improvement in Refining and Chemical Industries” (2021–2024); completion of Phase I of the Public Utilities Island construction for the Changxing Island Petrochemical Industrial Base; and large-scale application of domestically manufactured critical equipment (adsorption towers and simulated moving bed units) for its PX plant. Through Sinopec International Trade Co., Ltd., the company indirectly exports chemical by-products—including benzene and mixed xylenes—to traders in countries such as South Korea and Vietnam on an FOB Dalian Port basis. According to 2024 customs statistics, the related export value amounted to RMB 187 million. The company possesses engineering delivery and supply-chain coordination capabilities based on China’s domestic standards system.
