Continuous emission monitoring systems (CEMS) are used by manufacturers and producers that have combustion and other forms of emissions releases as part of their processes. These systems provide the information required for regulatory reporting. A recent news announcement, Emerson’s New Hybrid Laser Process Gas Analyzer Reduces Costs for Continuous Emissions Monitoring, describes purpose-built technology to […]

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 […]
