[Haichuan Project Information] Baofeng Energy’s coke gasification to produce 600,000 tons/year olefins project was successfully started
Thread Content
Baofeng Energy announced on the evening of June 1 that the company's first public investment project, the coke gasification to produce 600,000 tons/year olefins project (hereinafter referred to as the "raised investment project"), the front-stage coke gasification to produce 2.2 million tons/year methanol project, was successfully launched on May 29 and produced qualified methanol products. The project uses the world's largest single-set production capacity of 2.2 million tons/year methanol synthesis tower and the country's largest 105,000 Nm?/h air separation unit, creating many industry firsts. Innovative integration of top domestic and foreign equipment technology to promote the technological upgrading of domestic large-scale equipment. According to Baofeng Energy, the 105,000-ton air separation unit and 2.2 million-ton/year methanol synthesis unit selected for the 2.2 million-ton methanol project are the largest domestic equipment. Their first operation and success will effectively promote the application improvement and technological upgrading of important domestic equipment, and make a positive contribution to the localization process of large-scale equipment in the coal chemical industry. The integration and application of advanced device technology also builds comprehensive advantages for the project such as low unit consumption, high synthesis efficiency, and low operating costs, and simultaneously achieves both economic and social benefits of high efficiency and low emissions.
Why choose coke as the gasification raw material? Usually coal is used as the raw material for gasification. It always feels awkward to turn coal into coke and then degasify it.
Is it because of this factor that the coal coking process removes or separates other fractions and the coke gas production process is simpler and easier to purify? ?
All 100 wealth points have been evaluated today. :lol
Haha, I also guessed that the coal chemical industry has too many direct liquefaction, indirect liquefaction, direct gasification and indirect gasification. A layman can only watch the excitement and see if any experts can tell me what Baofeng’s gasification route is.
There is no such thing as direct gasification or indirect gasification. I have two posts dedicated to introducing coal-to-liquid technology and coal gasification technology. You can check them out.

Helpful, thank you, professional post
This line of thinking is a possibility. However, although I have not done a technical comparison, I personally think that the cost of direct gasification from coal is much lower than that of regasification of coal through coke. Baofeng's coke gasification is probably a last resort. It already has coke production equipment. When the coke market is not good, it uses this method to digest production capacity.
After a brief understanding, this project initially adopted Lurgi's fixed-bed crushed coal gasification. At that time, coke was in a downturn, and the purpose was to absorb excess coke production capacity. Later, it was changed to entrained bed gasification (probably still a space furnace). It is actually inappropriate to use coke.
