en.Wedoany.com Reported - On March 29-30, China Hengyi Energy Technology (Turpan) Co., Ltd. held the process package review meeting for its 2.4 million tons/year high-quality fiber-grade coal-to-ethylene glycol project. The meeting brought together Hengyi Energy, Pujing Chemical, China Chengda Engineering Co., Ltd., and several industry experts, completing the reporting and technical demonstration of the core content of the process package. This marks the official transition of this super-large coal-to-ethylene glycol project from the technical scheme phase into the deepening phase of engineering design.
The project is located in the Coal-based New Materials Circular Economy Industrial Park in Turpan City, Xinjiang Uygur Autonomous Region, with the core goal of producing 2.4 million tons/year of high-quality polyester-grade ethylene glycol. According to public information, Hengyi Group, the parent company of Hengyi Energy, is a globally renowned polyester and chemical fiber enterprise. This move into Xinjiang aims to strengthen the risk resistance capability of its integrated "coal-fiber-fabric" industry chain through resource-end layout.
At the technical execution level, the project adopts the complete ethylene glycol process technology and proprietary catalysts from Shanghai Pujing Chemical, with China Chengda responsible for the overall engineering design. The project utilizes internationally advanced coal gasification and syngas-to-ethylene glycol technology routes. In addition to the main production of 2.4 million tons of ethylene glycol, it will also co-produce high-value-added by-products such as dimethyl carbonate and coal-based ethanol. Test data shows that the supporting proprietary catalysts have reached industry-advanced levels in both conversion efficiency and product selectivity.
To meet the increasingly stringent carbon footprint requirements of the energy industry by 2026, the project is simultaneously equipped with carbon capture and storage (CCS) technology, green power coupling, and circular economy supporting facilities. The R&D team aims to achieve the chain conversion of coal from a traditional fuel to new chemical fiber materials by optimizing key process links such as the PDS feeding system and other key technologies.
Currently, the review team has proposed multiple constructive optimization suggestions for the process package. The next step involves all parties improving the engineering design parameters based on the meeting minutes and accelerating equipment procurement and civil construction. The construction of this project will significantly enhance the self-sufficiency rate of domestic high-end polyolefin and polyester raw materials.
From an industry perspective, the 2.4 million-ton capacity scale will make this project a benchmark in China's coal-to-ethylene glycol field. Through the application of green power coupling and CCS technology, Hengyi Energy is actively building a low-carbon chemical materials demonstration route. This integrated layout not only reduces the carbon emissions per unit of product but also provides a referential technical paradigm for the green transformation of the coal-to-chemicals industry.
