Industrial Exhaust Emission Control

  •  Filters can operate at temperatures up to 1000C
  •  Backpressure of the filter when clean is low, < 1" H2O or <2.5 millibar
  •  Efficiently removes grease and oil particles
  •  Can be regenerated in process
  •  Handles gas stream flows up to 500,000 CFM or 850,000 m3/hr

Thermal Oxidizer Catalyst Cleaning

Industrial plants normally control exhaust emissions by heating the entire exhaust stream to a high temperatures with gas burners to allow catalyst-coated ceramic bricks to oxidize the pollutants. This system represents a costly waste of energy in gas consumption and is a large emitter of CO2. The CerX ceramic fiber filter system traps particulate over a long period at the ambient exhaust temperatures, then periodically, supplies auxiliary heat for a short period of time to oxidize the trapped material to clean the filter cartridges. The ambient filtration period may be several hours or several days. The auxiliary heating cycle is less than two hours. Natural gas operating cost can be reduced to less than 5% that of thermal oxidizers. CO2 emissions are proportionally reduced.

Thermal Oxidizer Pre-filtering

Many thermal oxidizers require high maintenance cost due to sticky or oily particulate fouling of the catalyst beds. The CerX filter system can remove the fouling agents before they reach the catalyst section to reduce these maintenance costs. The CerX system can be periodically cleaned, as stated above.

Carbon Credits

A thermal oxidizer system that has been “carbon capped” for continuously burning natural gas to operate the catalyst bed can realize substantial “carbon credits” by installing the CerX filter system. Its periodic high-temperature cleaning cycle can reduce CO2 emissions by as much as 95%.
