Air emissions from the refining sector. Analysis of E-PRTR data 2007-2017
This report is an updated version of the Concawe Report No 4/18 providing a review of the air pollutant emissions data submitted by national authorities for oil refineries in the European Pollutant Release and Transfer Register (E-PRTR) from 2007 to 2017. Detailed analyses are given for six pollutants of interest (SOx, NOx, NMVOCs, benzene, CO2, and PM10).
Emissions of all the six pollutants reviewed have decreased significantly between 2007 and 2017: SOx by 65%, NOx by 45%, NMVOCs by 38%, benzene by 50%, CO2 by 20%, and PM10 by 65%. The mass of crude processed over the same eleven-year period has reduced by 9% (based on assumptions taken to determine the transformation input for 2017). When emissions are expressed as t per Mt of crude processed the reduction between 2007 and 2017 is: 61% for SOx, 40% for NOx, 32% for NMVOCs, 45% for benzene, 12% for CO2, and 61% for PM10.
