CH4 emissions estimation following OGMP level 5 (specific FE and measurements with alternative methodologies)

EHS Techniques carried out a wide emissions study to detect and measure emissions from vents, fugitive and from unburned methane in the Natural Gas sector. EHS Techniques carried out a wide emissions study to detect and measure emissions from vents, fugitive and from unburned methane in the Natural Gas sector. Different technologies were used, including infrared detection (OGI) and its quantification (QOGI), direct flow measurement (HFS) and the use of specific emission factors following EN 15446 once sufficient representative data had been obtained.
