Meet current and future regulatory requirements with Servomex expert gas analysis technology

Crowborough, UK, February 2022 – Global gas analysis experts Servomex has launched the Laser 3 Plus Environmental helping plant operators meet with legislative requirements.

With integrated auto-validation software to ensure highly consistent measurement accuracy, the Laser 3 Plus Environmental Tunable Diode Laser (TDL) analyzer is a compact, reliable solution for accurate continuous emissions measurements of ammonia (NH3).

Although NH3 is not currently regulated as a hazardous air pollutant under the United States’ Clean Air Act, some US states regard it as a precursor pollutant for the creation of particulate matter of 2.5 microns (PM2.5) and find that 5 ppm NH3 in emissions can cause eye and respiratory irritations.

The Environmental Protection Agency (EPA) strongly recommends that analyzers used for continuous ammonia (NH3) monitoring in combustion emissions standards set out in Performance Specification 18 (PS18) are met. Many US state regulatory agencies are targeting the precursors that create PM2.5 as a pathway to lower PM2.5 emissions, so EPA PS18 looks set to become the basis of future regulation.

Additionally, Procedure 6 (40 Code of Federal Regulations Part 60, Appendix F) states that all continuous emissions monitoring system (CEMS) equipment must also be able to perform daily quality tests. This means that any downtime can affect the validation of an analyzer and may incur significant financial penalties.

With the Laser 3 Plus Environmental’s auto-validation software enabling compliance with Procedure 6, the analyzer’s non-contact, low-maintenance TDL sensing techniques minimises downtime, keeps operational costs low and ensures customers are ready to meet the legislative requirements of the CEMS market.

Rhys Jenkins, Spectroscopic Product Manager, of Servomex, said: “This will allow our customers to meet or even exceed the performance requirements of EPA PS18 for cross stack continuous emissions monitoring, avoiding needless downtime or inaccurate NH3 concentration that can lead to costly fines.”
