CEM Systems

 

In order to provide the most comprehensive array of services to our clients, AirSource Technologies, Inc. has equipped four mobile field trailers with modern instrumentation and ancillary equipment to perform various onsite measurements. Our Continuous Emission Monitor (CEM) systems are well suited for either providing continuous evaluation of an emission source, or for conducting certification testing of our client’s CEM systems. AirSource Technologies’ CEM systems consist of three subsystems:

 

1. The analytical system

2. The sampling and conditioning system

3. The data acquisition system

 

The analytical system typically includes the following major components.

 

Parameter  Detection Principle Make and Model Resolution
O2 Magneto Pneumatic Horiba CMA-331 .01 %
CO2 Non-Dispersive Infra Red Horiba CMA-331 .01 %
CO Non-Dispersive Infra Red Horiba CMA-331 1 ppm
NOx  Chemiluminescence Horiba CLA-311 1 ppm
SO2  Non-Dispersive Infra Red Western Research 721AT2 1 ppm
THC (VOC) Heated Flame Ionization Detector California Analytical HFID 300 1 ppm

 

The sampling and conditioning component provides general protection to the analytical system by controlling environmental variables such as moisture and particulate matter, thus insuring proper operation of the instrumentation. This system is capable of testing in the harshest industrial environments.

 

AirSource Technologies’ data acquisition system provides "real time" data calculations specific to client requested formats.

 

Our capabilities include:

 

bullet

Logging of up to 16 channels simultaneously

bullet

Correction of emissions to 7%/15% O2 or 12% CO2 reporting bases

bullet

Real time calculation of emissions (g/hr, ppm, lb/hr, lb/mbtu)

bullet

Rolling hourly average of emissions for BIF and RCRA incinerators

 

We are also capable of providing redundant instrumentation for simultaneous measurements such as inlet/outlet testing for establishing Destruction Removal Efficiency (D.R.E.).

 

All components of AirSource Technologies’ CEM system conform to EPA guidelines.

 

       

Additional Continuous Emission Monitoring Capabilities

Destruction and Removal Efficiency (DRE) Studies

Relative Accuracy Testing (CEMS & PEMS)

Calibration Error/Calibration Gas Audits

Predictive Emission Monitoring System (PEMS) Validation
