Air pollutant emission estimation methods for E-PRTR reporting by refineries
Report no. 4/17: This report is an update of the Concawe publication “Air Pollutant Emission Estimation Methods for EPER and PRTR Reporting by Refineries”.![Optical gas imaging: from qualitative to quantitative](https://www.concawe.eu/wp-content/uploads/Optical-gas-imaging-625x675.png)
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](https://www.concawe.eu/wp-content/uploads/2018/04/Capture-3-642x675.png)
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](https://www.concawe.eu/wp-content/uploads/report-3-588x675.png)
