en.Wedoany.com Reported - China Energy Investment Corporation has publicly tendered for the technology license, process package compilation, training, and technical services for a single-line 50,000-ton/year ethylene propylene diene monomer (EPDM) rubber project as part of the Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project in Yulin Chemical. The bidding results have now been announced. The tender number is CEZB260102581, commissioned by China Energy International Engineering Consulting Co., Ltd. on behalf of Guoneng (Beijing) Cross-Border E-Commerce Co., Ltd. After evaluation and bid award procedures, the winning bid results have been published.
Meanwhile, the public tender for the design services of the project's production support base (3rd round) has also been initiated, with tender number CEZB260300046. The tenderee is Guoneng Yulin Chemical Co., Ltd., and the funding source is self-raised. This design service project is divided into one bid section, with the proposed construction site located in the Science and Innovation City of Yulin City, Shaanxi Province, covering a total land area of approximately 78 mu. The main building functions of the base include a staff training center, corporate exhibition hall and lecture hall, shift dormitories, employee cafeteria, sports and cultural center, as well as an underground garage and civil air defense facilities. The service period extends from contract signing until the project passes completion acceptance and is registered.
The Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project is a new construction project located in the Qingshui Industrial Park North Area of the Yulin Shenfu Industrial Zone in Shaanxi Province, with a total investment of 79.836 billion yuan, including environmental protection investment of 6.228 billion yuan, accounting for 7.8% of the total investment. The project covers key areas such as coal liquefaction, coal gasification, naphtha methanol coupled cracking, MTO, polycarbonate, and coal-based biodegradable materials, comprising a total of 38 process units, along with corresponding storage, transportation, and utility facilities. The product range includes coal-based special fuels (such as coal-based jet fuel and coal-based diesel), gasoline, coal liquefaction asphalt, coal-based biodegradable materials, paraxylene, mixed aromatics, and polycarbonate. The project was approved and initiated by the National Development and Reform Commission in March 2015.
The pioneering project—Phase I—has a total investment of 13.6 billion yuan, located in the Qingshui Coal Chemical Park North Area of the Yulin Shenfu Industrial Zone, covering an area of approximately 14 hectares. The construction scope includes a co-production of 1.8 million tons/year of methanol and 400,000 tons/year of ethylene glycol. The full process flow was successfully completed by the end of 2020, producing qualified methanol, and on November 21, 2021, the 400,000 tons/year ethylene glycol unit also smoothly produced qualified products. The project further utilizes the intermediate product ethylene glycol to produce coal-based biodegradable material polyglycolic acid (PGA). On September 19, 2022, the 50,000 tons/year polyglycolic acid (PGA) biodegradable material demonstration project successfully completed the full process flow and commenced production, marking the world's first 10,000-ton-scale coal-based biodegradable material demonstration project achieving industrial production.
