Announcement on Hengyi Energy Technology (Turpan) Co., Ltd.’s investment of 25.7 billion yuan to build a project for producing 2.4 million tons per year of ethylene glycol from coal for high-quality fibers, using 4 sets of 3,000 t/d Shaohang Maiwei furnaces
Thread Content
Recently, the Management Committee of Turpan Economic Development Zone published a notice regarding the approval process for Hengyi Energy Technology (Turpan) Co., Ltd.’s project to produce 2.4 million tons per year of high-quality ethylene glycol from coal, which is used in fiber production. Hengyi Energy Technology’s 2.4 million tons per year production facility for high-quality fiber-grade ethylene glycol using coal in Turpan uses lignite from the Aidinghu mining area as raw material. Through gasification, syngas is produced; this syngas is then transformed and purified to separate carbon monoxide and hydrogen. Carbon monoxide, along with externally purchased methanol and domestically produced nitric acid, is used to produce dimethyl oxalate, which is subsequently combined with hydrogen to yield ethylene glycol. The project is equipped with an ammonia synthesis unit, and the ammonia produced serves as a raw material for the nitric acid production plant. Project investment: 2,570,180 million yuan. Process configuration: The overall process starts with lignite from the Aiding Lake mining area as raw material; it is gasified to produce syngas. Part of this syngas undergoes heat recovery before entering a low-temperature methanol washing unit, where sulfur and carbon dioxide are removed. Subsequently, deep cryogenic separation is carried out to separate hydrogen and carbon monoxide, with the carbon monoxide obtained being sent to the DMO unit as feed gas. Another portion of the syngas undergoes isothermal shift to adjust the hydrogen-to-carbon ratio, and after methanol washing, most of it is sent to the 1# PSA pressure swing adsorption unit for hydrogen extraction. Hydrogen and dimethyl oxalate produced by the DMO unit are used to produce ethylene glycol. Another small portion is sent to 2#PSA to produce hydrogen, which is then sent to the ammonia synthesis unit. Liquid ammonia is sent to downstream facilities to produce nitric acid. Vaporization: 4 sets of 3,000 t/d Aerospace Maiwei furnaces, 4 in operation with 1 as backup. Transformation: Set up a 2-series transformation system and a 2-series untransformed system. Purification: Series 2. Dalian University of Technology Low-temperature Methanol Wash. Sulfur recovery: Series 2. Domestic third-level conventional Claus sulfur recovery technology. H2/CO separation: Series 4. Including cryogenic and PSA hydrogen extraction. Dimethyl oxalate: Series 4. Ethylene glycol: Series 4. The production capacity for a single series is 600,000 tons. Synthetic ammonia: single train. 40,000 tons per year. Nitric acid: single series. Single compression method. 30,000 tons per year. Air separation: Series 3. One set of oxygen at 105,000 m3/h. On June 6, 2025, the Development and Reform Commission of Gaochang District, Turpan City, Xinjiang, released a public notice regarding the public consultation process for the social stability risk assessment of Hengyi Energy Technology (Turpan) Co., Ltd.’s project to produce 2.4 million tons per year of high-quality ethylene glycol derived from coal for use in fiber production. The project details are as follows:
Project Overview: Project Name: Hengyi Energy Technology (Turpan) Co., Ltd.’s 2.4 million tons per year coal-based ethylene glycol project for high-quality fibers. Project Owner: Hengyi Energy Technology (Turpan) Co., Ltd. Project Type: New construction. Location: The project is planned to be built within the Coal-Based New Materials Circular Industry Park in Turpan Economic Development Zone, with its eastern boundary at open land, its western boundary at the Resource Road in the southern mining area, its southern boundary at Area 2 of Aidinghu Coal Mine, and its northern boundary at the planned S346 provincial road. The land designated for this project is industrial land; the site is relatively flat, and there are no special environmentally sensitive sites such as historical and cultural heritage sites, natural heritage sites, or famous landmarks. Project overview: The 2.4 million tons per year production facility for high-quality fiber-grade ethylene glycol from coal at Hengyi Energy Technology (Turpan) Co., Ltd. requires an investment of approximately 25.7 billion yuan; all of this funding will come from the company itself. The total land area required is around 2.5375 million square meters, with a planned construction period of 36 months. Construction scale and scope: 2.4 million tons per year of high-quality ethylene glycol produced from coal, with accompanying production units, auxiliary production facilities and utility systems, as well as supporting infrastructure for production services. This includes gasification units, purification units, H2/CO separation units, ammonia synthesis units, nitric acid production units, DMO production units, ethylene glycol production units, air separation units, boiler units, finished product storage areas and utility systems. It also encompasses the overall layout of the new project, storage and transportation facilities, pipe galleries and underground pipelines, water supply and power supply systems, road lighting, laboratory facilities, fire protection systems, telecommunications infrastructure, mechanical and electrical maintenance services, gas protection stations and information systems, landscaping, as well as necessary production service facilities. The construction and operation of the project will directly create over 2,000 jobs, while also generating indirect employment in related industries such as coal mining and logistics transportation, accounting for more than 10,000 jobs. Attract people to settle down through industrial clustering, alleviate local employment pressures, and fulfill the central government’s requirement of \"enriching the people and strengthening border areas\". At the same time, cooperation between the project and the Production and Construction Corps can strengthen integration between the military and local areas, providing economic support for the long-term stability of Xinjiang. The completion of the project can significantly increase local government revenues; through government investment in improving infrastructure and raising the standard of culture and education, it will benefit residents throughout the region.
