DownloadsWhat are particulate emissions?
Particulate emissions are tiny particles and droplets in the air that are made up of hundreds of different chemicals. Most are formed in the atmosphere as a result of chemical emissions from power plants, industries and automobiles. To reduce PM pollution, the EPA regulates inhalable particles smaller than 10 micrometers.
Tri-Mer Ceramic Filter Systems are 99%+ efficient for the collection of particulate matter. The typical level of PM emissions control at the outlet of Tri-Mer ceramic filters is 0.001 grains/dscf (2.0 mg/Nm3).
This is true even with very heavy inlet loadings. Higher inlet loadings simply mean that the filters are cleaned more frequently with reverse-air pulse cleaning, while on-line. PM emissions of PM10, PM2.5, and submicron PM1.0 are captured with high efficiency.
Tri-Mer filters control PM by a means very different from that of traditional filters. The special qualities of the filter surface result in the particulate matter being captured on the face of the filter tubes without deep penetration into the filter walls and body of the filter. This allows for complete and repeated cleaning of the surface.
Particulate Control – Tri-Mer Ceramic Catalyst Filter system operates at much higher temperatures and can be configured to remove SOx, NOx, CO, mercury, dioxins, and Cement O-HAPs.
Ceramic filters are also available with embedded catalyst that removes NOx at relatively low temperatures, as well as dioxins and Organic HAPS. Get more information on Tri-Mer’s hot gas filtration system.
For particulate emissions control, typical filter life is 5 to 10 years. These applications generally have temperatures above 300°F, with most applications in the 400°F to 900°F temperature range.
The practical limitation is the carbon steel housings; the filters themselves are operational to 1650°F, but stainless steel housings and available valves and sensors limit applications to below 1400°F. The filters are often used when there is a high fraction of PM2.5 and submicron particulate in the PM emissions.
Ceramic filters are highly effective for submicron PM: equal to fabric bags and better than ESP. Read about the advantages of choosing Tri-Mer Ceramic Filters vs. Dry ESP or Fabric Filters.
