Recently, a bidding dust concerning the global coal chemical industry pattern was settled by the Aiding Lake in Turpan, Xinjiang. Nanjing Dunxian Chemical Technology Co., Ltd. stood out from multiple bidding companies and successfully won the order for 8 sets of isothermal transformation furnaces for Xinjiang Hengyi Energy Technology (Turpan) Co., Ltd.'s annual production of 2.4 million tons of high-quality fiber coal to ethylene glycol project. This high-value core equipment contract marks China's independently developed large-scale isothermal transformation technology officially standing at the center of the global coal chemical stage.

Billion dollar layout in Turpan

Zhejiang Hengyi Group, a Fortune 500 company, regards Xinjiang as a strategic hub and plans to invest a total of 150 billion yuan within 5 to 8 years to build a complete industrial loop from coal to polyester new materials in the local area. The winning project this time is the opening work of this grand blueprint. The total investment of the first phase of the project is 25.7 billion yuan, with a construction period of 36 months. It is expected to be completed and put into operation in the first half of 2028. After reaching production capacity, it can produce 2.4 million tons of high-quality ethylene glycol annually, while producing 76000 tons of industrial grade dimethyl carbonate, 15600 tons of ethanol, and 37000 tons of sulfur as by-products.

Local technology solves temperature control problems

The DX-V controllable heat transfer converter won by Nanjing Dunxian this time is the crystallization of the company's years of technological accumulation. The core innovation lies in utilizing the principle of water phase transition heat absorption to transfer the large amount of heat generated by chemical reactions out of the catalyst bed in a timely manner, thereby avoiding local overheating. Compared with traditional technology, this equipment has a more uniform gas distribution, significantly improved carbon monoxide conversion rate, minimal bed temperature fluctuations, and significantly extended catalyst replacement cycle. Eight sets of large-scale isothermal transformation furnaces will jointly form the core of the purification system for the project. Keywords: New energy latest news、New energy latest reports

Black coal moves towards a green chain

The project's raw materials are sourced from brown coal in the local Aiding Lake mining area. This low-grade coal, which was previously only used as fuel, will now undergo a magnificent transformation towards high-end chemical raw materials along the technological path of gasification, purification, and synthesis. The project is synchronized with low-carbon technologies such as carbon capture and storage, green electricity coupling, and circular economy to achieve green production processes. The connection of this vertically integrated industrial chain, from a piece of coal to two threads and then to a piece of cloth, provides a replicable model for the transformation and upgrading of traditional coal production areas.Editor/Gao Xue
