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
slide3
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

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

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!
