On January 23, 2026, the Shaanxi Provincial Department of Ecology and Environment issued a public notice regarding the acceptance status of the environmental impact assessment documents for the Yulin coal-based ethanol and acetic acid downstream products project (major changes). Shaanxi Yanchang Petroleum Yulin Coal Chemical Co., Ltd. was established in November 2008. It is a wholly-owned enterprise funded by Shaanxi Yanchang Petroleum (Group) Co., Ltd. Since its establishment, the company has built a methanol production facility with an annual capacity of 200,000 tons, acetic acid production facilities with an annual capacity of 400,000 tons along with related equipment, a CO2 liquefaction facility with an annual capacity of 250,000 tons, a demonstration project for producing oil from syngas with an annual capacity of 150,000 tons, and a facility for the deep processing of heavy fractions derived from Fischer-Tropsch processes with an annual capacity of 30,000 tons. At present, the deep-processing facility for heavy fractions of 30,000 tons per year of Fischer-Tropsch products has been built but not yet completed with final acceptance; all other facilities have gone through the necessary environmental protection procedures and have been put into operation. The current production capacity is 200,000 tons per year of methanol (used to produce downstream products such as acetic acid), 400,000 tons per year of acetic acid, 150,000 tons per year of oil products, and 250,000 tons per year of carbon dioxide. Due to changes in market demand, the project owner optimized the downstream processing routes. While keeping the 300,000-ton vinyl acetate production facility unchanged, the 200,000-ton/year acetate ester facility and the 200,000-ton/year EVA facility were transformed into facilities for producing 30,000 tons/year of ultra-high molecular weight polyethylene, 50,000 tons/year of vinyl oil, 50,000 tons/year of alpha-olefins, and 100,000 tons/year of polyolefin elastomers. The revised project was re-registered with the Yulin Administrative Approval Service Bureau on January 24, 2025 (project code: 2206-610836-04-01-293862). Yulin Coal Chemical Ethanol Acetic Acid Downstream Products Project (Material Change): Nature of the project construction: Renovation and expansion. Location: The production facilities and associated infrastructure are located in plot C17, on the south side of Yuma Avenue, in the southern area of the coal chemical industry zone within the Yuheng Industrial Park; the shift workers’ dormitories and canteens are located in area C13. Construction contents: Construction of a 300,000-ton/year vinyl acetate plant, a 50,000-ton/year vinyl oil plant, a 30,000-ton/year ultra-high molecular weight polyethylene plant, a 50,000-ton/year alpha-olefin plant, and a 100,000-ton/year polyolefin elastomer (POE) plant, along with supporting utility systems, auxiliary production facilities, infrastructure in the area in front of the factory, shift worker dormitories, etc. Project investment: The total investment for this project is 9,859,954,900 yuan, of which 2,751,400,000 yuan is allocated to environmental protection measures, accounting for approximately 2.79% of the total project investment. Number of employees: 750 new positions to be added. Working system: The working system is four shifts and three rotations, with 333 days (8,000 hours) of work per year.
