Recently, Xinjiang Ehang New Materials Co., Ltd. issued several tenders for its demonstration project on the clean and efficient comprehensive utilization of coal at a capacity of 5 million tons per year. Bidder: Xinjiang Yihang New Materials Co., Ltd.
Location: Shengxiong Tongxin Industrial Park, Toksun Energy Heavy Chemical Industry Park, ** Xinjiang Uygur Autonomous Region (Alehui Town). The bidding for the equipment required for the coal cleaning and efficient comprehensive utilization demonstration project with an annual capacity of 5 million tons at Xinjiang Yihang New Materials Co., Ltd. covers 4 types of core equipment as well as related systems (including the equipment itself, drive units, auxiliary systems, instrumentation for control, special tools, spare parts, etc.). Specifically, these include: 1) Electrostatic tar collectors: 6 units, along with supporting equipment such as high-voltage constant-current power supplies and control cabinets ； 2) Horizontal tube coolers: 6 units (specification Fn=7500m², upper section 5380m², lower section 2120m²) ； 3) Gas fans: 6 units, including explosion-proof variable-frequency motors, explosion-proof light oil stations, protection boxes, and other associated equipment ； 4) Condensate pumps: 2 units (horizontal single-stage single-suction centrifugal pumps), including explosion-proof main motors, couplings, bases, and other associated equipment. Technical requirements: 1) General requirements: All equipment must be capable of withstanding the extreme climate conditions in the Toksun area (extreme maximum temperature of 48.8°C, extreme minimum temperature of -20.4°C, strong winds), and must comply with relevant national and industry standards. Equipment located in explosion-proof areas must meet the corresponding explosion-proof rating requirements. 2) Special requirements: Electrostatic tar catcher: The gas handling capacity per unit is 80,000–90,000 m³/h; the operating voltage is 55–70 KV; the grounding resistance should be less than 2 Ω; the verticality deviation of the unit itself should be less than 8 mm ； Horizontal tube cooler: Single-unit processing capacity of 62,499 Nm³/h, operating pressure drop of 800–1000 Pa; the casing is made of Q235B material, while the heat exchange tube bundle consists of 20# seamless tubes ； Gas fan: The selected flow rate for each unit is 1600 m³/min; it features frequency conversion control, and its sealing type is double-end mechanical seal (with nitrogen purge gas). The motor has an explosion protection rating of ExdIICT4 and a protection rating of IP65 ； Condensate pump: flow rate of 160 m³/h, head of 30 m; the fluid is tar (containing a small amount of water and dust); explosion protection rating EXDIICT4Gb, protection rating IP55. Scope of the tender for the equipment and foundation works in the tar-ammonia water separation section of Xinjiang Yihang New Materials Co., Ltd.’s 5 million tons per year demonstration project for clean and efficient comprehensive utilization of coal: design, manufacturing, supply, installation, commissioning, and after-sales service for all aspects related to the equipment in the tar-ammonia water separation section (including circulating ammonia water pumps, tar intermediate pumps, etc.), custom-made equipment (including ammonia water slag removal tanks, ammonia water intermediate tanks, etc.), as well as equipment foundations and associated works (including foundation treatment, anti-corrosion measures, grounding, etc.) ； The 5 million tons per year demonstration project for the clean and efficient comprehensive utilization of coal, operated by Xinjiang Yihang New Materials Co., Ltd., is located in Ailehui Town, Toksun County, Turpan City, Xinjiang Autonomous Region. It adopts a model based on the graded upgrading of oil-rich coal combined with circular economy principles. Utilizing the high-quality long-flame coal resources with very low sulfur content and high calorific value available in the Heishan mining area of Toksun County, the project employs a multi-product coal pyrolysis technology system. It also includes facilities for carbon dioxide capture and the production of methanol using green hydrogen, thereby creating a closed-loop industrial chain that covers the graded utilization of coal as well as the recycling of carbon resources. Tuoxun County is located in the Central Tianshan metallogenic belt and possesses rich mineral resources. Among them, coal resources are particularly abundant, with proven reserves exceeding 15 billion tons, and an additional 28 billion tons in reserves is expected to be discovered. This coal type is a long-flame coal with extremely low ash, phosphorus, and sulfur content, as well as a high calorific value; it possesses a high added value when subjected to further processing, and is an excellent coal source for producing coal-to-oil, coal-to-olefins, and activated carbon. The demonstration project for the clean and efficient comprehensive utilization of 5 million tons per year of coal carried out by Xinjiang Yihang New Materials Co., Ltd. has a total investment of 7.1 billion yuan. It will be constructed in two phases, with the first phase scheduled to be completed within 33 months. This phase will enable the processing of 5 million tons of raw coal per year, resulting in the production of high-value products such as 2.26 million tons of upgraded coal, 300,000 tons of liquefied natural gas, and 100,000 tons of green methanol. Additionally, a domestically leading deep-processing system for coal tar will be established as part of this project.
