Underground Coal Gasification: A Brief Review of Current Status
Coal gasification is a promising option for the future use of coal. Similarly to gasification in industrial reactors, underground coal gasification (UCG) produces syngas, which can be used for power generation or for the production of liquid hydrocarbon fuels and other valuable chemical products. As compared with conventional mining and surface gasification, UCG promises lower capital/operating...
متن کاملa study of underground coal gasification (ucg) wastewater and sludge
underground coal gasification (ucg) is a non-conventional method of extracting gas from coal. the primary advantage of ucg is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world’s coal reserves by an estimated 70%; for this reason, ucg has been implemented at sites around the world. however, the gaseous, liquid and solid waste streams which ac...
متن کاملEarly Ideas in Underground Coal Gasification and Their Evolution
This article follows the development of early UCG (underground coal gasification) ideas. Historical facts are discussed mainly from the technological perspective and early experiments in UCG are analyzed. Our search for the first successful UCG experiment brings to light a new finding, which was commonly overlooked in previous reviews. We also outline the key role that engineer and inventor A. ...
متن کاملUCGVision: Underground Coal Gasification Process Data Visualization Aspects
This work presents the UCGVision system designed for underground coal gasification process visualization, prediction, and monitoring. The possibility to visualize the ongoing reactions during the process is crucial for better insight into the process itself. Moreover, the system task is to give researchers and in the future process supervisor a tool to observe the current state of the process b...
متن کاملComparative Assessment of Gasification Based Coal Power Plants with Various CO2 Capture Technologies Producing Electricity and Hydrogen
Seven different types of gasification-based coal conversion processes for producing mainly electricity and in some cases hydrogen (H2), with and without carbon dioxide (CO2) capture, were compared on a consistent basis through simulation studies. The flowsheet for each process was developed in a chemical process simulation tool "Aspen Plus". The pressure swing adsorption (PSA), physical absorpt...
