  1. Particulate Matter Emissions from Industrial Sources (With the Iron & Steel Industry as an Example) U. Karl, O. Rentz French-German Institute for Environmental Research (DFIU/IFARE) University of Karlsruhe (TH), Germany Workshopof the UN/ECE Task Force on Integrated Assessment Modeling on the Potential and Costs for Controlling Primary Emissions of Fine Particulate Matter Laxenburg, 23 - 24 November 2000

  2. Particulate Matter (PM) Emissions from Industrial Sources • Contents • Introduction - Major sources of PM emissions in industry • Fine Particulate Matter - Fractions of PM 10 in emissions from direct and fugitive emission sources • PM Emission Reduction Measures - Process integrated emission control - End of pipe techniques - Control of secondary emissions • Conclusions

  3. Major Contributors to PM Emissions from Industry • Mining of coal, lignite, metal ores • Manufacture of non-metallic mineral products • (Cement, lime, glass, bricks and tiles) • Manufacture of basic metals • (Iron and steel, non-ferrous metals) • Manufacture of basic chemicals / fertilisers • Manufacture of wood products • (Chipboard, fibreboard) • Manufacture of food products • (Mills, sugar production) • Waste incineration

  4. Fractions of Fine Particulate Matter Direct Emissions Depending on dust control equipment Fabric filters 95 - 98 % PM10 Electrostatic precipitators 95 % PM10 Scrubbers 90 % PM10 Cyclones 50 - 60 % PM10 Fugitive Emissions Highly uncertain information; estimated fractions: Storage and handling 20 % PM10 Industrial building venting up to 75 % PM10 Reference: Remus R.: Feinstaub - Entstehung und Quellen der Feinstaubemissionen - Neue gesetzliche Regelungen; VDI Berichte 1478, 1999

  5. Particulate Matter Emissions from Pig Iron Production Contribution of Fugitive Emissions Reference: Emission Control at Stationary Sources in the Federal Republic of Germany,Volume II DFIU/IFARE 1997

  6. Process Integrated Emission Control Example: Emission Optimised Sintering Reference: EIPPCB Iron & Steel BREF January 1999

  7. Emission Optimised Sintering - Multi-Pollutant Emission Reduction (compared to conventional sintering) Reference: EIPPCB Iron & Steel BREF January 1999

  8. Inertisation as an End of Pipe Measure Example: Blast Furnace Operation - Fume Suppression During Casting Description: Enclosed transport route for the hot metal; Minimal space between molten metal and covers; Flooding with nitrogen, if necessary Reference: Emission Control at Stationary Sources in the Federal Republic of Germany, Volume II, DFIU/IFARE 1997

  9. Conventional Casting Bay Dedusting System Reference: Emission Control at Stationary Sources in the Federal Republic of Germany,Volume II DFIU/IFARE 1997

  10. Economic Aspects of Dust Suppression Systems Reference: EIPPCB Iron & Steel BREF January 1999

  11. Control of Secondary Emissions Primary and secondary off-gases from a converter

  12. Collection Efficiency of Secondary Emissions Example: Basic Oxygen Steelmaking Reference: EIPPCB Iron & Steel BREF January 1999

  13. Particulate Matter (PM) Emissions from Industrial Sources • Summary • Depending on the sector, major contributions result from fugitive emission sources. • Process integrated measures often entail multi-pollutant emission reduction. • EoP Measures: Encapsulation of dust emission sources can lead to significant advantages compared to suction hoods and conventional dust abatement. • Concerning the abatement of secondary emissions the collection efficiency is of mayor importance. • Conclusion • Dust control is more than fabric filters!
