This paper focuses on the variations of process parameters in underground coal gasification (UCG) and explores suitable sensors selection and monitoring units design for control, monitoring, and precaution during the gasification process. Experimental work is conducted on a laboratory scale, and individual control and monitoring techniques of different operational process parameters are described, aiming for successful UCG operation and complexity reduction.
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.
