Method of measuring surface emissions of methane
Méthode de mesure des émissions du méthane à la surface
Résumé
The detection and hazard evaluation of gas emission from the ground are a complex problems. In order to quantify and qualify these gas emissions and check gas migrations special measuring methods are required. The research done at INERIS resulted in a reliable and appropriate methodology using a flux chamber. This methodology is intended for detecting, quantifying and qualifying gas discharges, but can also be applied to verify the effectiveness of the preventive means used for reducing emissions (sealing operations, drawing off gas, etc.). The method has already been applied in an operational manner for diagnostics and appraisal on a number of sites (landfills, old mines, etc.). Although originally designed for measuring methane flows, it is fully useable in or transposable to any similar Situation of gas flows emitted by the ground, subject possibly to some specific modifications. The fundamentals of the method are protected by European patent No. 96-05996.
