Particulate matter emissions from industrial sources

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 filters95 - 98 % PM10

Electrostatic precipitators95 % PM10

Scrubbers90 % PM10

Cyclones50 - 60 % PM10

Fugitive Emissions

Highly uncertain information; estimated fractions:

Storage and handling20 % PM10

Industrial building ventingup 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!
