Optical gas imaging: from qualitative to quantitative
New technology capable of quantifying fugitive emissions using infrared imaging may eventually serve as a full replacement for Method 21.
Experimental evaluation of the flux chamber technique to determine VOC emissions from a water surface
Report no. 3/17: Tests have been undertaken under controlled conditions in a wind tunnel to compare the emission fluxes from an open tank containing an aqueous toluene solution with those determined using a lux chamber mounted on the water surface. The tests showed...
An evaluation of an optical gas imaging system for the quantification of fugitive hydrocarbon emissions
Report no. 2/17: This report provides the results of a preliminary study undertaken to test the performance of a quantitative optical gas imaging (QOGI) system. This has been developed to measure the mass emission rate of hydrocarbon leaks from industrial process...
