Air Pollution Control System

Submicron Particulate Matter Removal System

Paramount offers unique solutions with a complete line of submicron aerosol removal systems to remove from traditional aerosol and mist elimination applications to the removal of difficult-to-control sticky, oily, or soluble aerosol emissions.

The Cleanable High Efficiency Filtration device manufactured under the trade mark of CHEAF is a wet collector system which uses either a polymeric, metallic or glass fiber filtration mat to remove submicron particulate matter from the exhaust gas streams. For many applications, the CHEAF unit offers substantially reduced energy consumption over that required for a venturi scrubber on the same application. The CHEAF can be used on most particulate matter which is not sticky or viscous and which does not deposit scale on the fiber mat.

The two different types of CHEAF are the fully cleanable type and the renewable media type. Fully cleanable CHEAF units can be used

  • On dust emissions in the mineral and mining industries,
  • On inorganic chemicals, dryers and calciners,
  • On prill tower emissions in the manufacture of ammonium nitrate and urea.
  • For spray dryer emissions in the food products and flavouring industries and
  • The perfume manufacturing industries.

Where acidic emissions are encountered, the renewable media CHEAF unit is used. These industries include

  • Container glass and plate glass manufacturing
  • Furnace grade phosphorous manufacturing
  • Galvanizing emissions and several others

Single units of CHEAF can be built to handle gas flows up to 680000 m3/hr (400000 acfm).

The typical areas of applications of the CHEAF units are:

• Phosphoric Acid Mists
• Hydrochloric Acid Mists
• Nitric Acid Mists
• Detergent Manufacturing
• Food and Flavouring Spray Dryers
• Ammonium Nitrate Prilling & Pelletizing
• Compressed Air Filtration
• Urea Prilling and Pelletizing

• Soda Ash Calciners
• Soda and Borosilicate Glass Furnaces
• Vacuum Pump Discharges
• Galvanizing Emissions
• Potassium Chloride Dryers
• Molten Salt Baths
• Electroplating Bath Emissions
• Phosphorus Furnace Emissions
• Process Gas Filtration
