On January 7, the website of the Ministry of Ecology and Environment announced the acceptance of the environmental impact assessment documents for the coal-to-olefins upgrade demonstration project of Sinopec Great Wall Energy and Chemical (Inner Mongolia) Co., Ltd., marking a critical step toward the project's implementation. The project is located in the Dalu Industrial Park of the Jungar Economic Development Zone in Ordos, Inner Mongolia, with a total investment of 22.067 billion yuan, of which approximately 1.6 billion yuan is allocated for environmental protection, accounting for 7.27% of the total investment, highlighting the project's green development orientation.
The project adopts an integrated industrial chain model of "coal-to-methanol—methanol-to-olefins—polyolefin deep processing," with coal as the core raw material. It plans to construct multiple core production units and supporting facilities. These include: a 2.26 million tons/year coal-to-methanol unit, covering the entire process of coal gasification, purification, methanol synthesis, and sulfur recovery; a 2.26 million tons/year MTO unit (including OCC), enabling the efficient conversion of methanol to olefins; and polyolefin units with a total capacity of 900,000 tons/year, comprising a 250,000 tons/year loop polypropylene unit, a 200,000 tons/year gas-phase polypropylene unit, a 350,000 tons/year polyethylene unit, and a 100,000 tons/year EVA/LDPE unit.
Additionally, the project will include supporting facilities such as an air separation unit, an IGCC thermal power station, as well as public utilities and auxiliary production facilities to ensure the stable operation of the industrial chain. Upon completion, the project will further extend the deep processing industrial chain of coal in Inner Mongolia, enhance the comprehensive utilization efficiency of resources, and contribute to the development of high-end chemical industries in the region.
