Underground Coal Gasification » GSTC - Global Syngas

The process can be halted by stopping the injection of the oxygen or air. After the coal is converted to syngas in a particular location, the remaining cavity (which will contain the left over ash or slag from the coal) may be flooded with saline water and the wells are capped. However, there is also growing interest in using these cavities to ...

Dry Syngas Purification Processes for Coal Gasification Systems

Syngas contains various impurities that are derived mainly from coal and subsequent chemical reaction during the gasification process. Because the gasification operation is performed at high temperature, generally higher than 1000°C, condensed matter, as well as gaseous components, is carried on the syngas to the outlet of the gasifier.

Economic overview of a two-agent process for underground coal

Abstract. Underground Coal Gasification (UCG) is a mining-gasification process that produces synthesis gas from in situ coal by injecting air (or oxygen and steam) and extracting the produced gas via boreholes. The resulting synthesis gas (‘syngas’) produced by UCG can be used directly as a fuel-gas or deep-cleaned to produce many other products like chemicals, liquid fuels, hydrogen and ...

Cost comparison of syngas production from natural gas conversion and underground coal

Jun 15, 2014  Underground coal gasification (UCG) is a promising technology to reduce the cost of producing syngas from coal. Coal is gasified in place, which may make it safer, cleaner and less expensive than using a surface gasifier. UCG provides an efficient approach to mitigate the tension between supplying energy and ensuring sustainable development. However, the coal gasification
