On November 15, 2024, the gasification unit of the coal-to-olefins upgrade demonstration project in Baotou, Inner Mongolia, supervised by Luoyang Petrochemical Engineering Construction Group Company, officially started construction. Shenhua Baotou coal-to-olefins gasification uses five pulverized coal gasifiers with a daily coal input capacity of 2,000 tons per furnace jointly developed by Colin Energy Company and China Shenhua Coal-to-Liquids Chemical Company. Gasifiers co-process waste liquids. The Shenhua Baotou Coal-to-Olefins Upgrading Demonstration Project plans to use coal as raw material, undergo gasification in a Colin furnace, conversion, low-temperature methanol washing, and methanol synthesis to produce 2 million tons of methanol/year and 750,000 tons of polyolefins. Through simultaneous planning and construction with new energy sources, it will achieve deeply coupled development of coal chemical industry with green electricity, green hydrogen, and green oxygen. After the completion of the project, Shenhua Baotou's annual methanol production capacity will increase to 3.8 million tons, and its annual polyolefin production capacity will increase to 1.35 million tons. On November 6, the general contracting meeting for the EPC project of the gasification unit of the Shenhua Baotou coal-to-olefins upgrade demonstration project was held at Ningbo Engineering Company. On October 18, the winning candidates for the EPC general contracting public bidding project for the gasification unit of Baotou Chemical Shenhua Baotou Coal-to-Olefin Upgrade Demonstration Project were announced. First successful bidder: Sinopec Ningbo Engineering Co., Ltd. Tender quotation: 1.5 billion yuan. The bidding announcement shows that the interim handover time of the project plan is: August 15, 2026. On August 16, after multiple rounds of negotiations, * * The energy group Shenhua Baotou coal-to-olefins upgrade demonstration project gasifier (including supporting burners and accessories) purchase contract was successfully signed. Shenhua Baotou coal-to-olefins upgrade demonstration project signed a contract for five 2,000 tons/day Colin gasifiers. From August 20th to 21st, the gasifier start-up meeting was held at Dongfang Electric Group Dongfang Boiler Co., Ltd. located in Chengdu, Sichuan. The basic information of the project is learned, * * Energy Group Baotou Coal-to-Olefins Upgrade Demonstration Project is an upgrade demonstration project implemented by Guoneng Baotou Coal Chemical Co., Ltd. based on the world's first coal-to-olefins demonstration unit that has been in operation for many years. The construction scale is to produce 2 million tons of methanol and 750,000 tons of polyolefins per year. Through simultaneous planning and construction with new energy, it achieves deeply coupled development of coal chemical industry with green electricity, green hydrogen, and green oxygen. The project adopts advanced technology and energy-saving and environmentally friendly technology, and the key equipment is basically domestically produced. The energy efficiency and water efficiency indicators of the equipment have reached or exceeded the industry benchmark level. After the completion of the project, Guoneng Baotou Coal Chemical's methanol production capacity will be increased to 3.8 million tons/year, polyolefin production capacity will be increased to 1.35 million tons/year, and 7.8 million tons of coal will be converted annually. Next step, * * The energy group will also implement polyglycolic acid (PGA), new energy power electrolysis of water to produce green hydrogen, green oxygen and other projects based on the upgraded demonstration projects. According to reports, the coal-to-olefins upgrade demonstration project has a total planned investment of 17.15 billion yuan, and the construction site is located in Jiuyuan Industrial Park, Baotou City. In terms of technology, pulverized coal is used for pressurized gasification and combined with a methanol synthesis unit to produce 2 million tons/year of methanol (intermediate product, 100% basis). Methanol is processed through a methanol-to-olefins unit and olefin separation to produce intermediate products such as ethylene and propylene, and the final products are polyethylene and polypropylene. Among them, the polypropylene unit has a production capacity of 360,000 tons/year, and two units will be built. The project will take coal gasification-methanol-methanol-to-olefins as its main line. The main project consists of 11 sets of production units including coal gasification, purification, sulfur recovery, methanol, methanol-to-olefins, polyethylene, and polypropylene. Public utilities and auxiliary facilities fully rely on the reconstruction and expansion of existing projects and some new ones. Construction content includes: It consists of main engineering, public engineering, auxiliary facilities, environmental protection engineering, storage and transportation engineering and off-site slag dump. Main project: Air separation unit (including air compressor station), coal-to-methanol unit (including gasification, shift, low-temperature methanol washing, refrigeration station, sulfur recovery, methanol synthesis unit), MTO unit, olefin separation unit, MTBE/butene-1 unit, C4/C5+ comprehensive utilization unit, polyethylene and polypropylene unit, etc. Among them, public works and auxiliary facilities rely as fully as possible on the existing factory. 4 new circulating water plants and 1 chemical water treatment station were built ； Set up 3 flare systems and 1 ground flare. The elevated flares are high and low pressure hydrogen-rich flare systems, low pressure and low and low pressure heavy hydrocarbon flare systems, and sour gas flare systems. The three torches, high and low pressure hydrogen-rich torches, low pressure, low and low pressure heavy hydrocarbon torches, and acid gas torches, are designed as bundled torches and arranged on a torch tower. They are designed as fixed torches. The height of the entire plant's torches is 150 m. ； The ground torch is used to treat hydrocarbon-containing gases of the dual polymerization device, with a height of 30 m. Other public and auxiliary facilities will be adaptively transformed or expanded according to the upgrading demonstration project. Storage and transportation projects include: Coal unloading and storage, the whole plant tank area, loading and unloading pallets, warehouses, pipe corridors, in-plant railways and other projects are adaptively reconstructed and expanded. Environmental protection projects include: Waste gas treatment, wastewater treatment (biochemical treatment, water reuse device and salt evaporation and crystallization device), accident pool, wastewater buffer pool, etc. ； Waste alkali incinerator, off-site slag dump and hazardous waste temporary storage warehouse ； Noise control facilities, etc.
