\"Research on the Application of Large-Scale Coal Gasification Processes in Northern Shanxi\": Review Meeting Held for the Results of Industrial Testing of the Jinhua Furnace / Author/Source: Gasification World / Date: May 29, 2023 / Clicks: 6. On May 27, the China Petroleum and Chemical Industry Federation organized relevant experts to hold a review meeting in Beijing regarding the results of industrial testing of the Jinhua Furnace as part of the research on the application of large-scale coal gasification processes in northern Shanxi. The review committee deemed it feasible to gasify coal from northern Shanxi using Jinhua furnaces, and unanimously agreed to approve the review. The evaluation experts listened to the report on the results of the industrial test firing presented by the technical service provider, Beijing Qingchuang Jinhua Technology Co., Ltd., as well as the supplementary report on the industrial test firing provided by Lu’an Fengxi Linyi Branch. They also heard reports from representatives of the experts who were present at the test firing site. Following inquiries and discussions, four evaluation opinions were formulated. First, the trial firing data is complete, and the trial firing process was genuine and effective. Documents such as industrial trial firing plans, trial firing reports, and technical proposals, as well as original records of the trial firing, raw data from laboratory tests and analyses, meeting minutes, photos, videos, and other records of the process are all complete, accurate, and valid. Second, it is feasible to gasify coal from northern Shanxi using Jinhua furnaces. During the industrial trial operation, the gasification unit of the Jinhua furnace (a water-cooled wall gasifier for coal water slurry) operated stably, with all parameters within normal ranges, and there were no instances of overheating or overpressure. This industrial trial burn has proven that it is feasible to gasify coal from northern Shanxi using the Jinhua furnace. Third is a preliminary assessment of the gasification performance of Jinhua Furnace for coal gasification in northern Shanxi. Tests were conducted under three typical conditions: 100% coal from northern Shanxi + 2% limestone, 100% coal from northern Shanxi + 3% limestone, and 60% coal from northern Shanxi + 40% coal from Shenmu. The performance indicators included gasification efficiency, carbon conversion rate, cold gas efficiency, specific coal consumption, and specific oxygen consumption. Fourth are the conclusions and recommendations. The successful completion of the industrial trial firing of coal from northern Shanxi in the Jinhua furnace demonstrates that the use of this coal in the water-coal slurry gasification technology of the Jinhua furnace is feasible, providing technical support for the China National Coal Group Pingshuo coal-based olefins project. Finally, the review committee concluded that it is feasible to use Jinhua furnaces for gasifying coal from northern Shanxi, and unanimously agreed to approve the review. The total investment in the China Coal Pingshu Coal-based Olefins New Materials and Downstream Deep Processing Integrated Project is 29.78 billion yuan. The project is located in the Chaoyang New Materials Industrial Park within the Pinglu Economic and Technological Development Zone in Shuozhou City, Shanxi Province, and it involves the construction of facilities for producing 2.2 million tons per year of coal-to-methanol, 800,000 tons per year of methanol-to-olefins, as well as other facilities for downstream deep processing. Due to the high sulfur, high ash content, and high ash fusion point characteristics of the coal from northern Shanxi (Pingshuo coal), there are currently no precedents for the use of this coal in large-scale fluidized bed gasification processes. Through coal quality analysis, viscosity-temperature curve testing, and slurry formation performance tests, along with industrial pilot tests that yielded relevant reports, the appropriate large-scale gasification technology for using this coal was ultimately determined. On April 27, 2023, a summary meeting on the industrial trial operation of the slurry-fueled furnace for the research on the application of large-scale coal gasification technology in northern Shanxi was held at Fengxi Group in Yuncheng City, Shanxi Province. On February 27, 2023, China Coal Pingshuo Group Company entered into a technology development (commissioning) contract with Beijing Qingchuang Jinhua Technology Company for the research on the application of the coal-water slurry furnace gasification process in Pingshuo Group Company’s operations in northern Shanxi. Under this contract, Beijing Qingchuang Jinhua Technology Company was tasked with carrying out this research project. The water-cooled wall gasifier (Unit 4) of the Linyi branch of Fengxi Group is designed to handle a coal feeding rate of 600 t/d, with a gas production capacity of 100,000 m3/h per unit, and a design pressure of 4.0 MPa. Put into operation in 2011. Project Overview: The construction site for the China Coal Pingshu Coal-based Olefins New Materials and Downstream Deep Processing Integration Project is located in the Chaoyang New Materials Industrial Park, Pinglu Economic and Technological Development Zone, Shuozhou City, Shanxi Province. This project makes full use of the integrated advantages of coal, electricity, chemicals, water, and new energy in the Pingshu mining area; it utilizes high-sulfur, high-ash content coal as raw material and combines it with green electricity and green hydrogen as means to reduce carbon emissions, thereby producing high-end coal-based olefins new materials as part of an energy transition initiative. China National Coal Group focuses on developing large-scale coal chemical complexes in regions such as Inner Mongolia and Shaanxi, as well as Shanxi, and is planning coal-to-olefins projects. To date, China Coal Group, including its subsidiaries and companies in which it holds shares, has 5 olefin companies that are either in operation, under construction, or planned: China Coal Shaanxi Yulin Energy Chemical Co., Ltd. (Phases I and II), Inner Mongolia China Coal Mengda New Energy Chemical Co., Ltd., Shaanxi Yanchang China Coal Yulin Energy Chemical Co., Ltd. (Phases I and II), Zhongtian Hechuang Energy Co., Ltd., and China Coal Pingshuo Group Co., Ltd. Since 2010, China National Coal Group has established modern coal chemical projects in Yulin, Shaanxi, Ordos, Inner Mongolia, and Shuozhou, Shanxi. It has completed the 600,000-ton/year coal-to-olefins project in Yulin, Shaanxi; the 600,000-ton/year engineering plastics project in Ordos; the project in Tuoketuo that produces 1 million tons of synthetic ammonia and 1.75 million tons of urea per year; the 600,000-ton/year coal-to-methanol project of China National Coal Group Yuanxing; as well as a demonstration project for the comprehensive utilization of low-quality coal in Pingshuo, Shanxi. The group also holds shares in Shaanxi Yanchang China National Coal Group Yulin Energy Chemical Co., Ltd. (1.9 million tons/year of olefins), Zhongtian Hechuang Energy Co., Ltd. (1.37 million tons/year of olefins), and Hebei China National Coal Group Xuyang Coking Co., Ltd. Currently, the 1-million-ton/year coal-to-methanol project in Tuoketuo is under construction, and the second phase of the project in Yulin is in the planning stage. Coal chemical products mainly include olefins, methanol, urea, **, coke, etc., with an authorized production capacity of around 10 million tons.
