Streamline Emissions Monitoring with Proven Analyzer Technologies
Why Continuous Emissions Monitoring Matters
Refineries, chemical plants, and power facilities operate under strict environmental regulations that demand real-time emissions tracking. A Continuous Emissions Monitoring System (CEMS) continuously measures pollutants and translates the data into actionable compliance reporting.
While CEMS equipment does not control processes directly, it is vital for:
-
Demonstrating compliance with environmental permits
-
Avoiding costly fines and operational shutdowns
-
Achieving sustainability and ESG goals
Hot-Wet Sampling: Simplifying Accuracy
Most traditional “cold-dry” CEMS cool the gas sample to ~4 °C (39 °F) to remove moisture. This method introduces challenges:
-
Water-soluble gases like SO₂, NH₃, and HCl may dissolve, reducing accuracy
-
Added hardware such as chillers, condensate pumps, and moisture traps increases maintenance
-
Corrosion risks can shorten component lifespan
Hot-wet sample systems keep the entire gas stream above its dew point—often 160–190 °C (320–375 °F)—eliminating condensation and ensuring accurate measurement. Benefits include:
-
Preservation of all gas-phase pollutants
-
Simplified design with fewer moving parts
-
Increased uptime and reduced maintenance costs
