According to Sinochem New Network, on June 3, Nanjing Dunxian Chemical Technology Co., Ltd. announced that it had won the bid for the project undertaken by Xinjiang Hengyi Energy Technology (Turpan) to produce 2.4 million tons per year of high-quality fiber-grade coal-based ethylene glycol. The company secured the order to supply all 8 isothermal shift reactors required for this project. This is another instance of domestically produced core coal chemical equipment being used in a super-large-scale integrated polyester raw material project. It is reported that this project is part of the integrated coal-to-textile industry chain plan developed by Zhejiang Hengyi Group, one of the world’s top 500 companies, in Xinjiang. Hengyi Group plans to invest a total of 150 billion yuan in Turpan over the next 5 to 8 years, in order to build a comprehensive industrial cluster that covers coal mining, ethylene glycol production, and polyester fiber manufacturing. The total investment for the first phase of this ethylene glycol project amounts to 25.7 billion yuan. It is the fiber-specific coal-based ethylene glycol project with the highest planned production capacity among those under construction worldwide. The construction period is 3 years, with operations scheduled to begin in the first half of 2028. It is reported that the project will use locally available materials, with lignite from the Aiding Lake mining area in Turpan as the raw material, and will integrate advanced gasification technologies as well as the mainstream processes for producing ethylene glycol via catalytic conversion of syngas, along with a complete set of facilities for gasification, gas purification, and the synthesis and refinement of ethylene glycol. Once the project reaches full capacity, it will be able to produce 2.4 million tons per year of ethylene glycol for high-quality fibers, along with 76,000 tons of industrial-grade DMC, 15,600 tons of ethanol, and 37,000 tons of industrial sulfur. The project also incorporates low-carbon technologies such as CCS carbon capture and storage sowie the use of green electricity; by leveraging local coal resources, it enables the conversion of fuel into high-grade fiber raw materials, thus establishing a green closed-loop industrial chain from raw coal to ethylene glycol to polyester fabrics. According to Wang Qingxin, chairman of Nanjing Dunxian, the equipment awarded in this bid is the DX-V type controllably heat-transferred isothermal shift reactor developed by the company itself. It serves as the core equipment in the coal chemical shift unit, being used primarily for the conversion of carbon monoxide in crude syngas and for adjusting the hydrogen-to-carbon ratio of the syngas. This equipment directly determines the conversion efficiency and operating costs of the ethylene glycol production facility. This device utilizes the heat absorption during the phase change of water to achieve isothermal temperature control; it can quickly remove the heat generated by catalytic reactions, thereby ensuring uniform airflow distribution within the furnace, controllable temperature differences across the bed layer, and a high conversion efficiency for carbon monoxide. Compared with traditional adiabatic conversion equipment, this technology significantly extends the service life of catalysts, offering advantages such as energy savings and operational stability. It has been successfully applied on a large scale in several domestic coal chemical projects with production capacities of tens of millions of tons. Wang Qingxin said that winning the bid for the core equipment of Hengyi’s super-large ethylene glycol project marks the successful application of Nanjing Dunxian’s proprietary isothermal conversion technology in key projects of global leading polyester manufacturers. This paves the way for a new phase in their industrial cooperation, and it also adds further impetus to the efforts to develop domestic production of key equipment for large-scale coal-based ethylene glycol production.
