Latest developments in ash fusion coal gasification technology
Thread Content
Ash fusion coal gasification technology has been developed and applied by Shanxi Coal Chemistry Research Institute for more than 20 years. It is expected to be widely used in the country within 1 to 2 years. 1. In 2001, the atmospheric pressure ash fusion coal gasification technology was successfully launched in Shaanxi Chenggu Fertilizer Plant. Subsequently, the promotion of atmospheric pressure furnaces was carried out, but due to non-technical reasons, it could not be operated and promoted normally. 2. The pressurized 1.0Mpa semi-industrial gasification experiment conducted in Taiyuan this year is running normally. Next year, the technology’s pressurized 1.0Mpa gasifier is expected to be used in industry. 3. The 0.6Mpa ash fusion gasification furnace will begin industrial trial operation in early 2008. It deserves everyone's attention. 4. The industrial demonstration plant of pressurized 2.5Mpa ash fusion polygasification furnace will be put into operation within 2 to 3 years. The project has been approved * * Financial support from the 863 Program. By then, the processing capacity of the gasifier will be 1,000t/d. It can handle most types of coal including lignite to anthracite. Domestic technology and low investment deserve the attention of colleagues in the coal chemical industry at home and abroad.
2. The pressurized 1.0Mpa semi-industrial gasification experiment conducted in Taiyuan this year is running normally. Next year, the technology’s pressurized 1.0Mpa gasifier is expected to be used in industry. 3. The 0.6Mpa ash fusion gasification furnace will begin industrial trial operation in early 2008. It deserves everyone's attention. As far as I know, the 1.0Mpa ash fusion polygasifier should be located in Linyi Branch of Shanxi Fengxi Group, not in Taiyuan. In addition, I don’t know where the 0.6Mpa ash fusion polygasification furnace is built.
The 1.0mpa semi-industrial test was conducted in Taiyuan, and this year the test achieved a breakthrough in pressurization. Fengxi's industrial equipment is not running at all and is still parked. The 0.6mpa ash fusion polygasification furnace will be put into operation at Shijiazhuang Jinshi Fertilizer Factory early next year. In the second half of the year, it was operated by Jincheng Coal Mining Group. Worth your attention
No one likes such a good post? It's a pity that the successful 72-hour experiment of 1.0MPa ash fusion and polymerization has had a profound impact on my country's fertilizer companies. It not only reduced investment, but also reduced operating costs. Congratulations.
2007 was a year in which our institute achieved fruitful results in scientific research, and it was also a year in which our institute showed concentrated gains since it entered the innovation project. Technology development has achieved remarkable results. During the year, our institute's technologies such as high-performance material engineering, pressurized ash-melting fluidized bed pulverized coal gasification, methanol-to-high-quality gasoline, C9 fraction processing and utilization, and development of new maleic anhydride production processes have all made breakthrough progress, and good news has been reported frequently. High-performance materials have achieved stable production with large-scale preparation technology, and product quality is stable and up to standard, winning honors for our institute. Pressurized coal gasification achieved stable operation and active shutdown at 1.0MPa, and obtained engineering data for further amplification design. The methanol-to-gasoline technology has successfully started up the 3,500-ton/year industrial demonstration unit in one go, producing qualified No. 93 gasoline. ； C9 fraction processing technology enables the world’s largest single production facility to be successfully started up in one go ； The continuous refining process technology of maleic anhydride synthesis has realized the industrialization of the world's largest single 20,000-ton unit. Sorry to make a small advertisement!!:lol
The normal pressure ash fusion and gasification furnace can directly replace the normal pressure fixed bed gasification furnace, and 1.0MPa matches the 0.8MPa transformation of small nitrogen fertilizer. I wonder what is the basis for the pressure selection of the 0.6mpa ash fusion gasification furnace? Is it a standardized stress level or an individual case?
Ash melting and gasification is still very immature, and there are many problems with the operation of industrial equipment, and it is not yet able to operate continuously and stably.
Coal gasification can not only be used to make nitrogen fertilizer. Why can't there be 0.6MPA. Fixed bed gasification and coke oven gas also produce methanol. 0.6MPA gasification technology is useful for many manufacturers
Didn't I tell you that it can run stably now? Why don't you believe it, comrade?
Can the author give a more detailed introduction to the 0.6mpa ash fusion polygasifier of Shijiazhuang Jinshi Fertilizer Factory? Is it a technical renovation project or a new construction project? What is the project product? What is the process flow of the entire plant, especially the configuration and pressure levels of transformation and purification? Thanks
