Is the BGL gasification technology suitable for coal-to-gas production?
Thread Content
I read the forum’s own relevant introduction. It seems that BGL is suitable for IGCC; I’m not sure how it performs when used in coal-to-gas processes Please ask an expert to analyze it. Thank you!
BGL is an upgraded version of Lurgi’s product; it requires less investment, offers higher efficiency, and generates less pollution. However, the CO content in the syngas is too high, and the load on the conversion process is excessive； It is necessary to work in conjunction with new methanation processes such as HICOM.
The methane content in the gas from BGL is relatively low, at around 6%, making it unsuitable as natural gas.
The BGL furnace is quite good; it inherits some of the advantages of the Lurgi furnace – it features a high furnace temperature and high gasification efficiency. Experiments on waste treatment have also been conducted abroad, and its investment requirements are low. It is a furnace type with promising prospects for the future
BGL belongs to the category of liquid slag removal. Compared with the Lurgi gasifier, it features a higher gasification temperature (2000 degrees), a higher water decomposition rate, less water consumption, **reduced wastewater volume**, and a higher concentration of wastewater, which facilitates the recovery of useful components from the wastewater; moreover, the pressure required for wastewater treatment is lower； Compared to other oxygen-based gasification systems, the BGL gasifier consumes less oxygen, thereby significantly improving overall efficiency ； Carbon monoxide level increases as the conversion load rises ； The methane content is low, and the methanation load increases. But overall, BGL is still applicable to coal-to-natural gas......
It seems that the one with the clouds having dissipated is already in operation
Could you introduce the new methanation process? Including HICOM. Thank you!
