  • Questions and Answers on Using a Diesel Particulate Matter Filter in Heavy-Duty Trucks and Buses
    matter (PM), both of which contribute to. serious public health problems in the United States. Fortunately, there. are several techniques and technologies designed to reduce diesel pollution from existing trucks and buses. Using pollution control devices such as a diesel particulate matter filter
  • Organic Particulate Filtration
    without heat and the visible emission was acceptable from a customer and environmental regulation standpoint. However, when utilizing a cold process stream, particulate matter accumulated on the ceramic filter which had to be periodically cleaned by firing the burner. When the cleaning cycle began
  • Edge-Seal Mounting Support for Diesel Particulate Filters (.pdf)
    diesel exhausts [1-3]. Cyclical compression tests show proportional. Starting in 2007, DPF usage will be required as. increases in compressive force per unit of. particulate matter must be reduced from 0.10. weight, indicating a dimensional consistency in. g/bhp-h to 0.01g/bhp-h as measured
  • Soft Seal Design Feature and Advantages
    The soft seal option is particularly useful in analytical and clinical chemistry applications where inert valve materials are needed but particulate matter may be present in the fluid stream. Particulate matter typically damages soft material such as PTFE resulting in valve leakage in the valve
  • Innovative Ammonia Control
    Ammonia has increasingly become more of a. regulatory concern. Ammonia emissions into the. atmosphere have been linked to the formation of fine. particulate matter, while ammonia emissions in. wastewater are restricted because of the negative. affect the chemical has on rivers, lake, and aquifers
  • TefTEC Filters Protect Stored Citrus Juice (.pdf)
    A Florida based citrus juice processing plant needed to use vent filters to prevent bacteria, mold spores, particulate matter and water from entering the juice storage tanks. Ingress of these contaminants could cause spoilage of the juice. The customer had decided to use PTFE membrane filters due
  • Cylinder Pressure-Based Control of Pre-Mixed Diesel Combustion (.pdf)
    it offers the ability to lower the engine-out emissions of oxides of nitrogen (NOx) and particulate matter (PM). Microsoft Word - 2007-01-0773 Final.doc SAE TECHNICAL. PAPER SERIES. 2007-01-0773. Cylinder Pressure-Based Control. of Pre-Mixed Diesel Combustion. H. Husted, D. Kruger, G. Fattic, G
  • Industrial Boiler MACT Compliance Insights (.pdf)
    and Process Heaters 40 CFR 63 Subpart DDDDD (the "Boiler MACT"). The regulation was published in the Federal Register in September 2004. The regulation has many detailed nuances, but, in general, it regulates the emission of hydrogen chloride (HCl), particulate matter (PM), and mercury (Hg) from boilers
