  1. Implementation of the IPPCD – Data on ELV and BAT DG ENV, Brussel, 7 December 2010

  2. Outline • Introduction • Large combustion plants • General information • Emission sources to air • Emission sources to water • Chlor-alkali manufacturing • General information • Emission sources to air • Emission sources to water • General considerations

  3. Introduction “Provide available representative data on the limit values and environmentalperformancelaid down by a specific category of activities […] and, if apropriate, the best available techniques from which those values are derived. Describe how these data have been chosen and collected.” “[…] The reported data (on emission limit values and environmental performance) will be assessed to compare, as far as possible, the limit values set and the performanceachieved. A comparison could then be done with the BAT-associated emission levels in BREFs.” • Focus on two IPPC activities: • Large combustion plants (LCP) • Chlor-alkali manufacturing

  4. Introduction - LCP • Scope of report • Combustion activity • Producing electricity (including CHP) • Using solid or liquid fuels • Selection of installations: • Maximum of 6 installations per MS • Selection based on the emission inventories • 3 capacity classes: 50 – 100 MWth 100 – 300 MWth two top NOx emitters per class > 300 MWth • Emissions • To air • To water from waste gas treatment

  5. Large Combustion Plants • 113installations reported • Only 7new installations • Covers25Member States • 203combustion plants/emission sources to air reported

  6. 160selected emission sources for further analysis  covers 24Member States

  7. Large Combustion Plants 61% with capacity > 300 MWth 64% burning coal/lignite 160emission sources to air Only8% burning biomass 79plants use CHP

  8. Large Combustion Plants – ELVs vs. BAT AELs • Averaging period: BAT AEL Only ± 20% of reported ELVs DAV  All ELVs included • Reference oxygen content  recalculated when different

  9. 0

  10. Large Combustion Plants – ELVs vs. BAT AELs • CO • ELVs reported for 50% of the emission sources • BAT AELs not as clearly defined as for other pollutants • Comparison with values mentioned: similar result as for other pollutants etc. • Mercury • ELVs reported for 19% of the emission sources • 9 Member States reported ELVs • No BAT AELs mentioned in BREF for comparison

  11. Large Combustion Plants – Actual emissions Actual emissions • Reference year for emissions: 2006, 2007 or 2008 • Expressed as average of all measured values • Reference oxygen content  recalculated when different • Compared to  ELVs (when reported)  BAT AELs from the BREF LCP

  12. Large Combustion Plants – BAT End-of-pipe SO2 NOx End-of-pipe Primary Primary Dust

  13. Large Combustion Plants 57% with capacity > 300 MWth Waste water 70emission sources with from flue gas cleaning coal/lignite, liquid, biomass 91emission sources to water BAT AEL ~ emission levels associated with BAT FGD (DAV) Averaging periods

  14. SS (mg/L) COD (mg/L) Nitrogen compounds (mg/L) Sulphate (mg/L)

  15. Large combustion plants - BAT Emission prevention and abatement techniques • Reported for 24plants

  16. Introduction – Chlor-alkali • Scope of report • Chlor-alkali manufacturing installations • Different production processes, i.e. • Diaphragm cell process • Asbestos diaphragm cell process • Selection of installations • Maximum of 10 installations per MS • Priority to installations using • Mercury cell process • Asbestos diaphragm cell process • Emissions • To air • To water • Membranecellprocess • Mercurycellprocess

  17. Chlor-alkali manufacturing • 61installations reported 77 chlor-alkali production units • Only 2new installations • Covers 18member states • 103emission sources to air • 65emission sources to water

  18. Chlor-alkali manufacturing Asbestos diaphragm or mercury cell process 63% will convert to membrane cell process Closure is reported for 16% of the production units 21% of the units reported ‘other’ 64% of total capacity (55% of production units) converts by 2019-2020 An earlier conversion was reported for 19 installations 24 installations already closed mercury cell productions Conversionorclosure?
