Continuous Emissions Monitoring Systems

AquaGas Pty Ltd is a leading provider of Continuous Emissions Monitoring Systems (CEMS) for a wide range of industries, including power generation, oil, gas, chemicals, and pharmaceuticals. CEMS are a critical component of environmental monitoring and compliance programs, enabling companies to measure and report their emissions accurately and efficiently.

CEMS technology has come a long way since its inception in the 1970s. Today Continuous Emissions Monitoring Systems are highly sophisticated, using advanced sensors and software to provide real-time data on emissions of pollutants such as nitrogen oxides, sulphur dioxide, carbon monoxide, and particulate matter. This data is essential for regulatory compliance, as well as for identifying opportunities to improve process efficiency and reduce emissions.

AquaGas Pty Ltd offers a range of Continuous Emissions Monitoring Systems to meet the specific needs of its clients. These include.

  • Extractive CEMS | These systems use a probe to extract a sample of flue gas from a stack or duct and send it to an analyser for measurement.
  • In-Situ CEMS | These systems measure emissions directly in the stack or duct, without the need for sample extraction.
  • Dilution CEMS | These systems mix a sample of flue gas with clean air to dilute the pollutants and make them easier to measure.

All these systems rely on advanced sensors and analyzers to measure emissions accurately and reliably. AquaGas Pty Ltd works with leading manufacturers to ensure that its CEMS solutions meet environmental standards and codes in place in Australian states, New Zealand, and Pacific Islands.
