Underground coal gasification technology
Thread Content
In China, apart from XinAo, are there any other companies capable of carrying out coal underground gasification? Here are a few examples. Are carbon capture and storage technologies being used in China at the moment?
Perhaps underground coal-to-gas projects are easier to get approved than coal-to-natural gas projects
Who can list the main indicators of underground gasification? Carbon conversion rate? Emission of waste gas and waste liquid?
The biggest problem with underground coal gasification is the treatment of pollutant emissions. Leaving pollutants underground, out of sight on the surface, is not a solution to the problem, and the costs associated with this approach can be particularly high. SNOW can carry out such projects in China at low cost and quickly for promotional purposes, but from a strict environmental protection perspective, such projects should not be approved or promoted.
The disadvantages are also significant, as they remain hidden underground.
The environmental impact of underground gasification is enormous, and this is one of the reasons why developed countries in Europe and America are relatively averse to this technology.
The environmental pollution issues associated with coal in-situ gasification can be controlled. At present, the biggest challenge is how to control groundwater contamination. Coal in-situ gasification technology is also being developed in Europe and the United States, but in China, the wellless version of this technology is not yet mature. From a technical perspective, China University of Mining and Technology has a fairly advanced level of expertise in the well-based form of in-situ gasification technology!

The key to underground gasification lies in: how to drill wells, and the connection between the feed wells and the product gas wells! Operating the control parameters of the gasifier to ensure a stable production of high-quality syngas is the core of this technology!
