Vector’s Continuous Emissions Monitoring System (CEMS) is the complete solution to comply with EPA requirements. At our Pearland campus, the engineered package is designed and integrated to meet regulatory permits.

Cool-Dry Extractive Systems

Sample gas is extracted and conditioned to remove moisture prior to analysis
Conditioning at the CEM shelter
Heated sample line is required to keep the wet sample above its dew point until it reaches the moisture removal system

Hot-Wet Extractive Systems

No moisture removal – Moisture remains in the system throughout the sampling and measurement process
Sampling line, pump, and analytical equipment are heated to ensure the wet sample is analyzed hot, and gas is wet

Points to Consider

Temperature of the sample
Moisture content in the sample
Dew point of sample gas
Particulate content in the stack
Corrosive components in the sample
Range of the analyzer
Area classification, (safe area or class 1 div 2)
Maintenance requirement of the analyzer

Calibration

Calibration of an analyzer ensures that the analyzer is reading the certified gas correctly. Calibration gas sent to the probe and back to ensure no bias in sample system.

Testing

7 day drift prior to going live
Daily validation
Quarterly CGA
Yearly RATA
