ABSTRACT:
Combustible hydrocarbon gas from a contaminated zone of soil and/or water is abated by removing hydrocarbon gas from the zone, combusting a first portion of the hydrocarbon gas in an internal combustion engine to develop power and to produce hot exhaust gas, delivering a second portion of the hydrocarbon gas and the hot exhaust gas to a catalytic unit, passing the hot gas exiting the catalytic unit in countercurrent heat exchange relation to the second portion of the hydrocarbon gas before venting said exit gas and utilizing the power from said engine to remove hydrocarbon gas and contaminated water from the zone and to pump the gases throughout the system.
