Environmental Impact Assessment Approval for Great Wall Energy Coal-to-Olefin Upgrading Project
2026-5-21
Recently, the Ministry of Ecology and Environment has approved the Environmental Impact Report on the Coal-to-Olefin Upgrading Demonstration Project of Sinopec Great Wall Energy Chemical (Inner Mongolia) Co., Ltd.
Located in Dalu Industrial Park, Jungar Banner, Ordos City, Inner Mongolia Autonomous Region, the project takes coal as raw material and adopts processes including pulverized coal gasification, shift conversion, purification, methanol synthesis and methanol-to-olefin, alongside green hydrogen-coupled olefin production. It involves the new construction of an 800,000 tons/year coal-to-olefin facility. The project is designed with an annual raw coal consumption of 3.332 million tons and annual fresh water consumption of 7.7415 million cubic meters. Its major products cover 450,000 tons/year polypropylene, 350,000 tons/year polyethylene and 100,000 tons/year EVA/LDPE, with sulfur as the main by-product.
The main works consist of 12 production units including air separation, coal gasification, shift conversion, acid gas removal, refrigeration & compression, methanol synthesis, sulfur recovery, methanol-to-olefin, loop polypropylene, gas-phase polypropylene, polyethylene and EVA/LDPE units. Auxiliary facilities include gas-fired boilers, water supply and drainage systems and flare systems. Storage and transportation works cover coal conveying & storage systems, tank farms and finished product warehouses. Environmental protection facilities mainly comprise waste gas treatment units, wastewater treatment and recycling facilities as well as solid waste disposal installations.
The Ministry of Ecology and Environment requires the project to fully implement all pollution prevention and control measures and environmental risk prevention measures, cooperate with local governments to fulfill requirements such as regional emission reduction of major pollutants and equivalent carbon emission replacement, formulate and enforce stringent environmental management systems and monitoring plans, and establish timely and effective emergency response and coordination mechanisms.
