The combustion process leads to emissions which must be measured and reported to regulatory authorities in jurisdictions where process manufacturers and producers operate. Technologies such as Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) are used to sense and analyze industrial gases and monitor emissions.
Continuous gas analyzers that use the combination of these technologies can be found in many industries including chemical & petrochemical, refining, power, industrial energy, gas processing and marine. Some applications where these analyzers are used include continuous emissions monitoring, NOx reduction & ammonia slip, ethylene production & purity measurements, natural gas quality, and combustion control.
He opens introducing three new analyzers—the Rosemount CT5100, CT5400 and CT5800 analyzers. These products were designed to be suitable for hazardous locations and to perform low concentration measurements at very high speeds. The laser technology provides this speed and accuracy and long life up to 15 years of operation.
Through a process of chirping, multiple lasers can be sequenced in a single analyzer to measure up to 12 components up to once per second at sub-parts per million concentrations. In continuous emissions monitoring applications, NO, NO2, O2, CO, CO2, SO2 and other combustion byproducts. Samples can be run at very high temperatures—374 degF/190 degC—to keep hot/wet samples above the acid dew point and avoid the need for chillers upstream of the analyzer.
You can find more here on continuous gas analyzers in applications such as ethylene production & purity, continuous emissions monitoring, NOx reduction, fertilizer/ammonia slip, natural gas quality, and hydrogen & nitrogen purity.
