Ergo Exergy Welcome to Underground Coal Gasification
Nov 07, 2017 Welcome to Underground Coal Gasification Next year will mark 150 years since Wilhelm Siemens first suggested the idea of Underground Coal Gasification. And even though these years have seen great effort, ingenuity and achievement, UCG still has a distance to go before its broad commercial use becomes a reality.

Underground coal gasification UCG is considered to be an important means of coal utilization. However, the stability of underground coal gasification residuals has always been the focus of peoples attention. In this paper, based on the sequential chemical extraction and thermodynamic equilibrium calculation, the chemical forms and ...
underground coal gasification in kenya
Underground Coal Gasification UCG is a technology that involves drilling into coal seams and combusting the coal in situ in the presence of steam, air or oxygen to create syngas that is drawn to the surface through a production well. Recent UCG trials have resulted in serious contamination of surrounding soil and groundwater.
Underground Coal Gasification An Overview of
Underground coal gasication is the in situ conversion of coal into an energy-rich product gas. It takes place deep underground, using chemical reactions to consume the coal and grow a cavity. Gas wells, drilled into the coal seam, inject reactant air, oxygen, andor steam to sustain the reactions. Production wells then extract the product gas.
Underground Coal Gasification netldoegov
Underground Coal Gasification UCG takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the surface.1 Obviously ...
Underground Coal Gasification project in Thar Pakistan
The Thar project in Pakistan is developed by Cougar Energy UK CUK which is 47.8 owned by Ergo Exergys Australian technology licensee, Cougar Energy Limited, Australia. CUK has been developing the project since 2007 and holds a coal exploration license over 47.3 sq km located within Block III in the East of Sindh Province, Pakistan.
FUELLING THE FIRE End Coal
Underground Coal Gasification and Coal Chemicals processing is growing. These industries pose major risks to the environment in terms of air and water pollution as well as the huge significance for the fight against climate change from opening up previously inaccessible fossil fuel resources.

Underground coal gasification A nearterm alternate fuel
articleosti6460355, title Underground coal gasification A near-term alternate fuel, author Avasthi, J and Singleton, A M, abstractNote Since the beginning of this century underground coal gasification has been considered as an alternative to mining as a means of utilizing the coal resources not recoverable by conventional methods.
Review of underground coal gasification technologies and
Aug 31, 2012 Underground coal gasification UCG is a newer type of coal extraction that is being investigated and implemented around the world and that avoids most of the problems of mining coal. UCG involves the conversion of unmined coal, where coal seams are gasified, without mining, and synthetic gas syngas is produced for use in power generation or ...
