UCG (underground coal gasification) contaminant control program: simulation of post-burn UCG contaminant production. Final report, October 1986-September 1987

Technical Report ·
OSTI ID:6693980
; ; ; ;
This report presents the results of laboratory and modeling research directed towards minimizing the adverse impact of UCG on local ground-water quality. The Clean Cavern Concept was investigated using laboratory reactor simulations. Operating recommendations for UCG field testing were made based upon the results of the laboratory and numerical analyses of the simulations. The results of the research indicate that the adverse impact of UCG on local ground-water quality can be substantially reduced by following simple low-cost operating procedures when gasification of the coal has ended and by minimizing gas lost during gasification. Steam flushing of the hot UCG cavity immediately after gasification and sustained venting of the UCG cavity as it cools are the operating procedures recommended.
