In an era of escalating environmental regulations and the critical global drive for sustainability, accurately measuring methane (CH4) slip from LNG engines is not just essential – it’s a strategic imperative. Our UP-GHG-CEMS (Ultraportable Greenhouse Gas – Continuous Emissions Monitoring System) offers an unparalleled solution, driven by the superior combination of ABB/LGR’s highly specific OA-ICOS CH4 analyzer and the OXYDAN® DP7900’s advanced dilution sampling technology. The OA-ICOS analyzer is uniquely designed to provide precise CH4 measurements without interference from other exhaust gases, while the OXYDAN® ensures a remarkably clean sample, as pristine as the air we breathe. This powerful synergy guarantees unmatched accuracy in emissions analysis.
Engineered for true 24/7, 365-day continuous emissions monitoring (CEMS), the UP-GHG-CEMS operates with unprecedented reliability and requires no daily, weekly, or monthly routine service. This unique capability ensures continuous, high-fidelity data collection over extended periods – from days to weeks, months, or even up to a full year. This precise, real-time data is then ready for secure transmission to the cloud, making it the ideal foundation for rigorous regulatory compliance and the advanced, long-term training of your AI (Artificial Intelligence) and Machine Learning (ML) emissions models for all types of combustion engines.

The UP-CEMS concept introduces a versatile approach to exhaust gas monitoring. It enables the tracking of a wide range of emissions or the specific targeting of particular gases of interest, granting users complete flexibility.
The pursuit of alternative fuels for combustion engines and power generation plants has generated new demands for emission monitoring equipment across various research applications. Consequently, researchers require portable equipment and solutions to meet these evolving needs.
At the heart of this concept is the Ultra-portable Continuous Emission Monitoring System (UP-CEMS), meticulously engineered to extract exhaust gas samples and subsequently dilute it. The sample are then channeled to portable sensors available for CH4, CO2, C2H6, CO, NH3, HF, HCL, N2O and H2O.
By adopting the UP-CEMS Concept, you gain the ability to construct a bespoke continuous emission monitoring system precisely tailored to your requirements. The realtime sampling flow is fast 8 to 10 m/s and with the OA-ICOS with samling frequencies of 1 Hz makes realtime diagnostic of LNG engine easily performed.
Simplicity is a fundamental aspect of this plug-and-play concept, making it accessible for users of diverse backgrounds. Operating the system involves just three straightforward steps: attach the sampling probe to the sampling point (1 ¼” G female stud pipe), connect the analysers to the unheated sample line and finally, link the power and instrument air.
Despite it’s ultra-portable design, our system is built for continuous operation, year-round, serving as a reliable fixed Continuous Emission Monitoring System (CEMS).
