In the midst of increasing compliance demands for emissions monitoring and nitrogen oxide (NOx) measurement in industrial applications, companies now have the opportunity to move beyond costly consumables and complex gas sample treatment associated with aging, legacy measurement systems. Emerson’s new Rosemount™ CT4400 Continuous Gas Analyzer is the first purpose-built Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) analyzer designed to help plants reduce ownership costs and report emissions accurately in environmental monitoring applications measuring standard components, such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), carbon dioxide (CO2), and oxygen (O2).
Optimized for cold and dry applications running at ambient pressure, the Rosemount CT4400 analyzer offers the benefits of QCL/TDL technology, including high sensitivity, accuracy, improved stability, and low-drift performance in a configuration that allows fast, easy integration into existing plant infrastructure.
“Our customers are looking for a better way to measure emissions without the ongoing high costs or need for frequent calibration and complex sample preparation that requires NOx converters or ozone generators,” said Paul Miller, Managing Director for Rosemount Quantum Cascade laser analyzers, Emerson Automation Solutions in a press release. “The Rosemount CT4400 Continuous Gas Analyzer gives them an answer to their exact requirements in a configuration they can just plug into their existing systems and be off and running – at a lower cost than previously possible. The reduced complexity of the system over what most companies are used to results in higher reliability and analyzer availability with a lot less personnel time required.”
Because the system can hold up to four laser modules, it can measure up to seven application-specific gas components simultaneously, providing flexibility in continuous emissions monitoring systems (CEMS) applications. This simultaneous, multi-component analysis within a single analyzer reduces the need for multiple analyzers, as well as cost.
