Recently, the sixth International Symposium on the Promotion and Application of Multi-Nozzle Opposed Gasification Technology was held in Hefei, Anhui. The 4,000-ton class ultra-large coal-water slurry gasification unit and the 2,000-ton class waste boiler-quenching type gasification unit, jointly developed by Yankuang Group and East China University of Science and Technology, have successively entered the stage of practical implementation. They are at the forefront of advancements in coal gasification technology both domestically and internationally, offering new options for the technical selection in coal chemical projects. These units can further improve gasification efficiency and contribute to energy conservation and emission reduction. According to Meng Xiangjun, the chief engineer of Yankuang Group Co., Ltd., through the joint efforts of Shandong Yankuang Guotuo Technology Engineering Co., Ltd. and the Clean Coal Research Institute at East China University of Science and Technology, the multi-nozzle gasification technology has been successfully transferred to 57 projects both domestically and internationally through technology licensing. A total of 158 gasification units have been built as a result, and this technology has become one of the preferred options for coal chemical enterprises. Professor Guang Suo from East China University of Science and Technology mentioned that following the construction and operation of industrial demonstration units for water-coal slurry gasification with capacities of 1,000 tons, 2,000 tons, and 3,000 tons, during the 13th Five-Year Plan period, Yankuang Group and East China University of Science and Technology jointly undertook a key research and development project aimed at creating an industrial demonstration unit capable of processing 4,000 tons of coal per day per furnace. This is currently the largest water-coal slurry gasification furnace of its kind under construction in the world, and it is being built at Yankuang Inner Mongolia Rongxin Chemical Co., Ltd. and Inner Mongolia HuiNeng Coal Chemical Co., Ltd. Xie Kechang, former vice president and academician of the Chinese Academy of Engineering, said at the meeting that he hopes for further innovation in this technology; for example, considering direct gasification of coal at the mine site, combined with the construction of gasification plants, to transport the synthesized gas to enterprises in order to improve gasification efficiency. At the same time, it is hoped that the coal gasification industry will move toward modernization, larger scale operations, combined production processes, the use of multiple feedstocks, and standardization. By integrating technologies such as big data, artificial intelligence, and blockchain, intelligent and green coal chemical industries can be developed. Li Yongwu, president of the third council term of the China Petroleum and Chemical Industry Federation, pointed out that amid the profound restructuring of the global petrochemical industry, developing modern coal chemical industry not only aligns with China’s resource characteristics but also contributes to the structural adjustment of the industry, thereby fostering a new development model driven by innovation. “During the 13th Five-Year Plan period, modern coal chemical projects focused on coal-to-oil, coal-to-olefins, coal-to-ethylene glycol, and coal-to-gas all saw their production processes finalized, and the scale of this industry grew steadily. In the first half of this year, the coal-to-oil production capacity was 9.21 million tons, with a production volume of 3.086 million tons ； Coal-to-natural gas production capacity: 5.105 billion cubic meters; output: 1.57 billion cubic meters ； The production capacity for coal-based olefins remained at 8.12 million tons, with output at 3.925 million tons ； 3.32 million tons of ethylene glycol were produced from coal, with an output of 1.006 million tons. Advanced coal gasification technology is a key element in the development of modern coal chemical industry. The reaction mechanism behind coal gasification is highly complex, and controlling the coal gasification process is quite challenging. By adopting efficient and clean advanced coal gasification technologies, it is possible to promote energy conservation, environmental protection, and the efficient utilization of resources in the coal chemical industry. Additionally, such technologies can enhance the technical level of the industry’s equipment and boost the core competitiveness of coal chemical enterprises. Gu Zongqin, director of the Petroleum and Chemical Industry Planning Institute, pointed out that the coal chemical industry should make significant efforts to improve its capabilities in terms of technical equipment. In the field of coal gasification, key breakthroughs should be achieved in technologies and equipment such as 8.7 MPa large-scale water-coal slurry gasification, large-scale dry coal powder gasification, and gasifier waste heat recovery systems. Wang Shoujian, former chief engineer of China National Chemical Engineering Corporation, said that in the current market applications of mainstream coal gasification technologies, the multi-nozzle opposed water-coal slurry gasification technology accounts for 13.44% of the market share, ranking first among all types of gasification technologies; it also has the highest daily coal gasification capacity. Ranked by daily gasification capacity, the four main wet gasification processes show that the multi-nozzle (four-nozzle) type also comes first. During the conference, experts and scholars from home and abroad who are engaged in research on gasification technology, design, plant operation, and equipment manufacturing discussed and exchanged views on related technologies. Representatives from operating plants and equipment manufacturers were also invited to present the latest developments in plant operation and supporting equipment, thereby providing a comprehensive overview of the latest achievements in domestic gasification technology.
