Emissions Monitoring

Until recently the cost of continuous emissions monitoring (CEM), of exhaust gases from ships engines and boilers has been prohibitively costly and of questionable reliability. Most systems have been unable to measure the exhaust gas in-situ in the stack and have to resort to extracting samples of exhaust gas along heated pipes to a centrally located gas analyser. These older technologies require specialist attention to periodically check instrument zero and span. Mechanical parts such as gas valves and pumps add to the maintenance requirements and skills required to operate these systems.

Thanks to developments in the telephony and communications industry, diode laser light sources and solid state processing has transformed CEMs for ships. Highly reliable quantum cascade laser technology is now able to measure exhaust gases in situ as the gas passes through the stack. The technology does not require calibration, and is virtually maintenance free. But not only will this CEMs technology measure diesel engine and boiler plant exhaust gases, it will, in future, provide a range of emissions monitoring on board ship including monitoring leakage of volatile gases from hydrocarbon cargoes, ammonia slip on ships with NOx scrubbers and many more shipboard applications. Krystallon is leading the way in monitoring and managing emissions to provide ship owners with the tools to ensure compliance with ever tightening air quality regulations.
