Which gasification method is better for this type of coal? ?

It is recommended to prioritize the water-coal slurry gasification technology. Coal is a good option; it has a high ash melting point, so fluxes need to be added. Its calorific value is satisfactory, its reactivity is good, its ash content is low, and its slurry-forming properties are also excellent.

How about using SHELL? ? ? ?

The moisture content isn’t high; either shell or TEXCO will work. Use SHELL for higher efficiency.

Texaco is fine; if that’s not an option, domestic Texaco will do as well. Why spend a lot of money on Shell? It carries risks and often doesn’t work smoothly! Hehe. l

Based on the coal quality analysis data provided by the poster, I believe that the Texaco water-coal slurry gasification technology would be a suitable choice. Of course, the use of domestically developed four-nozzle water-coal slurry gasification technology is even more advisable. The Shell pulverized coal gasification technology is not suitable for this purpose; the main reason is that the percentage of volatiles in the coal type mentioned by the poster is very high. If the Shell pulverized coal gasification technology is used, then ensuring explosion safety in the coal grinding unit becomes a major issue. In other words, there are various problems associated with the grinding, storage, and transportation of pulverized coal, as coal with such high volatile content is highly prone to spontaneous combustion. The coal grinding unit needs to use large amounts of nitrogen to maintain an inert environment throughout the system, in order to avoid potential safety hazards； With the Texaco water-coal slurry gasification technology, such a problem does not arise, as the coal has already been converted into coal slurry; therefore, the impact of volatile matter becomes unimportant! As for the ash fusion point, it is slightly higher compared to Texaco’s water-coal slurry gasification technology; it might be possible to use solvents to reduce the ash fusion point of this type of coal!

With Luchi’s pressurized gasification technology for coal, the ash melting point is not very low, and the volatile content is high!

It is recommended to use TEXCO technology

Agree with the view from Floor 6. But given the quality of your coal, it is quite good; any gasification method can be used, provided that the design is adjusted accordingly to suit the characteristics of your coal. But it is recommended to adopt domestic technology – gas production from water-coal slurry. Is that patriotic? It starts with small actions.

Thank you all for your replies! ! ! ! ! !

The opinions from the 9th floor are very good; it’s necessary to consider cost-effectiveness, the return on investment, and whether there are any economies of scale. The poster can make a comprehensive consideration based on the actual conditions of the enterprise, including factors other than the type of coal; it can be said that coal is a good option, and gasification using pulverized coal, Endler furnaces, and space furnaces are all viable choices.

Could you be more detailed? ? ? Thank you! ! ! ! !

Depending on the production objectives and own capabilities, one can choose the Lurgi pressure gasification technology, domestic water-coal slurry gasification technology, or Shell powder coal gasification technology.

Pulverized coal gasification seems to be the more suitable option, especially for high loads. If water-coal slurry gasification is used as the sole coal gasification method, the ash content is relatively high and the ash fusion point is also high; mixing in coal types with lower ash fusion points can help reduce this issue. However, this approach may not be entirely suitable. On the other hand, the related technologies are well-developed – such as Texaco gasification and four-nozzle gasification techniques. SHELL’s and GSP’s pulverized coal gasification technologies, as well as those developed by East China University of Science and Technology, are all viable options. Lurgi’s pressurized coal gasification technology is also suitable, though the load capacity might be somewhat lower

If you have sufficient financial resources, it is recommended to use SHELL’s technology; air separation systems generate a large amount of nitrogen, making it easy to keep the oxygen level below 8% during coal grinding. Water-coal slurry still requires coal grinding, and both the refractory bricks and nozzles have a short service life, resulting in high operating costs. Luchi’s pressurized gasification technology for coal waste treatment will drive you crazy. Moreover, its production capacity is low and the operation is complex.

It is recommended to use the Lurgi coal gasification under pressure technology.

With Luchi, the gas-producing wastewater generated later is difficult to treat, and the treatment costs are also high
