Investigation of Subterranean Fuel Vapor Extraction and Destruction Using a Diesel Engine: Phase 2
Abstract
This project aims to remediate fuel spills by extracting hydrocarbon vapors from contaminated earth, and burning them in a diesel engine. The diesel engine destroys hydrocarbons more effectively than spark-ignited units currently in use, uses less fuel, and uses fuel commonly available on Air Force installations. A surplus diesel-powered air compressor was fitted with a torque measurement device and other measurement and control mechanisms for the project. The torque sensor's data was correlated to previously acquired data, with blower pressure used to gauge engine load. Testing using three different hydrocarbon gases in various concentrations to simulate well gases, at a variety of engine speed and load conditions, investigated how the engine would behave in actual use. Limitations were identified in terms of the concentration of gaseous fuel, hydrocarbon destruction efficiency and the fuel required. Further testing with intake air throttled, to simulate the pumping work the engine will have to perform when attached to a well, showed that the engine will run safely and continue to effectively destroy hydrocarbons so long as sufficient oxygen is inducted, either from the well or from fresh air. Conclusions from these data are presented, and recommendations for future testing are offered.
