On January 7, the official website of the Ministry of Ecology and Environment released a public notice, officially accepting the environmental impact assessment documents for the coal-to-olefins upgrading demonstration project of Sinopec Great Wall Energy and Chemical (Inner Mongolia) Co., Ltd.
According to the disclosed environmental impact assessment documents, the project is located in the Dalu Industrial Park of Zhungeer 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 project investment. The project adopts the "coal—methanol—olefins—polyolefins" process route, using coal as the initial raw material to first produce methanol as an intermediate product, then converting methanol to olefins (MTO) to produce olefins, and finally processing them into end products such as polypropylene, polyethylene, and EVA.
The core construction content of the project includes a series of key production units and supporting facilities: a newly planned 2.26 million tons/year coal-to-methanol unit (covering core process steps such as coal gasification, purification, methanol synthesis, and sulfur recovery), a 2.26 million tons/year MTO unit (including an OCC unit), and a polyolefins joint unit (specifically including a 250,000 tons/year loop process polypropylene unit, a 200,000 tons/year gas-phase process polypropylene unit, a 350,000 tons/year polyethylene unit, and a 100,000 tons/year EVA/LDPE unit). Additionally, supporting facilities such as an air separation unit, an IGCC thermal power station, and other utility and auxiliary production facilities will be constructed to ensure the stable operation of the entire project process.
