Operational process parameters of underground coal gasification technique and its control

Underground coal gasification (UCG) is a complex process as it depends on many factors such as geological and geo-hydrological analysis of strata, physical and chemical properties of coal, operational process parameters, seismic events, analysis of produced gases in real-time. This paper mainly identifies the process parameter variations due to underground coal gasification. This scientific study could help us to choose appropriate sensors, and design and develop suitable monitoring units for the control, monitoring and precaution during coal gasification. In this article, one experimental work is carried out in laboratory scale with the help of developed system. This paper also described individual control and monitoring techniques of different operational process parameters required for successful UCG operation. This is helpful for successful operation in the actual field and reducing its complexity.& COPY; 2023 Elsevier Ltd. All rights reserved.
