Contract for coal-to-ethylene glycol gasification signed by Inner Mongolia Kailuan Chemical Industry; license agreement for Jinhua furnace issued. Author/Source: Huahua Network – Coal Chemical Industry. Date: 2019-04-02. Clicks: 695. On March 27, Inner Mongolia Kailuan Chemical Industry Co., Ltd.’s 400,000-ton/year coal-to-ethylene glycol project entered into a patent implementation license agreement for the Jinhua furnace with Beijing Qingchuang Jinhua Technology Co., Ltd. Kailuan Group has invested 6.644 billion yuan in the construction of a project to produce 400,000 tons of coal-based ethylene glycol per year. Inner Mongolia Kailuan Chemical Co., Ltd. is the entity responsible for this investment, and it is building this facility in the Dong Industrial Park of Dalu New Area, Zhungeer Banner, Inner Mongolia Autonomous Region. The registered capital of Inner Mongolia Kailuan Chemical is 250 million yuan, with Inner Mongolia Kailuan Investment Co., Ltd. contributing 225 million yuan, accounting for 90% of it ； Inner Mongolia Shengli Resources Group Co., Ltd. invested 10 million yuan, accounting for 4% ； Liu Hua invested 7.5 million yuan, accounting for 3% ； Liu Yuma invested 7.5 million yuan, accounting for 3%. The Jinhua furnace was developed under the leadership of the Shanxi Clean Energy Research Institute at Tsinghua University, in collaboration with Beijing Qingchuang Jinhua Technology Co., Ltd., Yangmei Fengxi Fertilizer (Group) Co., Ltd., and Shanxi Yangmei Chemical Machinery (Group) Co., Ltd. It represents a new gasification technology that possesses independent intellectual property rights. The upper combustion chamber of the Jinhua furnace (coal slurry + membrane water wall + radiant waste boiler + quenching) adopts a vertically suspended membrane water wall structure, which is well-established in the field of thermal engineering. By utilizing the principle of slag protection, the gasification temperature can be increased to 1700°C, thereby completely overcoming the limitation imposed by the ash melting point of different coal types in conventional refractory brick gasification furnaces; as a result, this furnace can handle a wide range of coal types. The hydraulic circulation of the water wall adopts an intrinsically safe natural circulation design with forced circulation, enabling energy-efficient operation with low resistance and ensuring the safety of the water wall in the event of a power failure to the circulation pump, thereby **improving the operational reliability of the water wall**. A radiant waste boiler is installed at the lower part of the combustion chamber; its unique, highly efficient radiative heating surface structure is used to recover the sensible heat from the crude syngas, effectively preventing problems such as slag formation and ash accumulation. This allows the gasifier to produce high-quality steam alongside syngas, resulting in a syngas/steam co-production unit that improves energy utilization efficiency. The 400,000-ton coal-to-ethylene glycol project of Inner Mongolia Kailuan Chemical Co., Ltd. is a key project for the Kailuan Group in establishing a \"trinity\" development model that combines coal production, coal-fired power generation, and coal chemical industry; it plays an important role in implementing the Group’s strategy for transformation and development. The project is located in the Dong Industrial Park of Dalu New Area, Zhungeer Banner, Ordos City, Inner Mongolia Autonomous Region. It involves the construction of a production line capable of manufacturing 400,000 tons of ethylene glycol per year, along with the associated auxiliary facilities. The production process utilizes shift gas generated by Jinhua’s water-coal slurry gasification technology as the feed gas; Co-Mo catalysts are used for wide-temperature, sulfur-tolerant partial shift reaction to ensure that the ratio of H2 to CO meets the requirements for ethylene glycol production. Desulfurization and decarburization are carried out using low-temperature methanol washing, while the separation of H2 and CO is achieved through deep cryogenic separation ； H2 concentration is achieved using the PSA process; dimethyl oxalate is produced via methanol carbonylation, and ethylene glycol is obtained by hydrogenating dimethyl oxalate.
