Emissions Monitoring

Protea has been at the forefront of emissions monitoring systems for 20 years, as both a manufacturer and a user of stack emissions equipment. With the addition of the Procal range of continuous emissions monitoring analysers in 2017, Protea’s range of equipment covers almost all areas of emissions testing and we have solutions for most emissions gases – from combustion gas emissions to non-standard organic VOC emissions, CFC emissions and more.

Emissions Monitoring Requirements

Almost all industrial installations worldwide have a requirement to know and monitor their emissions to atmosphere, and take steps to reduce or limit their emissions. The quantities of gases that plants are permitted to emit are enforced by local regulation in each geographical region and can vary on the type of industry, plant or fuel that is being burnt.

In order to monitor the emissions, increasing instrumental techniques are the preferred method and certainly where a continuous emissions monitor is needed this can only be from on-line analysers. Protea has developed our range of gas analyser to operate within the stringent levels of performance needed in order for industry to monitor the emissions as required by the regulations. This includes the need for certification or accreditation of the analysers against performance requirement

Continuous Emissions Monitoring (CEMs)

Industrial plants operating continuously and with a high level of constant emissions are often required to install a permanent, fixed, continuous emissions monitoring system (CEMS). CEMs must have the required performance for the gases present in the stack – correct ranges, response times and accuracy of measurement – as well as have a reliable uptime and operation life so that the plant can continue to run.

Protea’s range of CEMs includes both extractive analyser systems – such as the atmosFIR CEM – or in-situ analyser that measure in-stack – the P2000 and P5000 analyser have a proven installation base globally in a wide range of industries.

Periodic or Portable Emissions Monitoring (PEMs)

Even if plants require permanent CEMS, there is also the need for approved stack emissions consultants to make periodic emissions measurements following approved methods and techniques. Historically this was using so called “wet chemistry” techniques of manual sampling and using external laboratories for sample analysis, but today instrumental techniques for periodic emissions measurements give as accurate readings with the added benefit of more data and on-site validation of data.

Protea’s multigas FTIR analysers are ideal for measurement of periodic stack emissions across a wide range of industries – from combustion gas process such as power generation or incineration, to complex multi-VOC emissions from pharmaceutical or chemical production plants.

Protea can also provide the support and training needed for periodic stack emissions consultants to follow and apply the required validations and tests of data that are required from the use of regulatory approved methods, such as CEN and ISO standards.


Frequently Asked Questions

Online gas analysers, such as those within Protea’s range of emission monitoring systems, measure the stack or flue gas concentration from an industrial process continuously. Protea’s CEMs are either extractive, pulling a sample of the emissions gas into the analyser, or in-situ, where the gas is measured within the actual stack. A real-time concentration is given, usually every minute, and then our emissions monitoring software (DAHS) provides averaging and reporting of the gases.

A real-time concentration is given, usually every minute, and then our emissions monitoring software (DAHS) provides averaging and reporting of the gases.
Continuous Emission Monitoring Systems (CEMS) are needed to provide a constant measurement of the compliance of an industrial process within its regulated emission limits.
A CEMS analyser, such as those within Protea’s range of gas analysers, measures the stack or flue gas concentration from an industrial process continuously.

A real-time concentration is given, usually every minute, and then our emissions monitoring software (DAHS) provides averaging and reporting of the gases.
Continuous Emission Monitoring Systems (CEMS) are widely used with power generation, oil & gas, chemicals, and waste incineration industries to provide a constant measurement of the compliance of an industrial process within its regulated emission limits.
Stack emissions testing is the continuous or periodic measurement of gas concentration and mass emissions from an industrial process to atmosphere. Stack testing usually is carried out to provide a gas concentration value to ensure the plant is within its permitted emission limit value (ELV).
A continuous emission monitoring (CEM) system, such as those within Protea’s range of equipment, measure the stack or flue gas concentration from an industrial process continuously. If a plant has a permit that stipulates continuous measurement of gaseous emissions, then a CEM will needed.
SA CEM is typically comprised of a single or multiple gas analysers, a dust or particulate sensor and a stack flowmeter. Typically, flue gas temperature and pressure is also measured. Protea can provide the complete range of equipment needed for a fully functioning CEM system, including data logging and reporting.
Protea’s CEMS have a lot of built in automated self-checking features, such as automatic calibration. However, operators are encourage to carry out daily and weekly visual inspections, replacement of filters every 1-3 months and to have a regular service contract that will involve 6 monthly service to the CEM.
Automated Measuring System (AMS) and Continuous Emissions Monitoring System (CEMS) in effect mean the same thing. AMS is a term preferred in some reference standards, such as the MCERTS/TUV performance standard EN 15267 and EN 14181, whereas CEMS is the more common term for equipment measuring industrial emissions.
In-situ Continuous Emissions Monitoring (CEM) analysers are flange mounted to the emissions point, with an in-situ sample cell inserted into the stack. Installing an in-stack CEM analyser removes the need for costly and high-maintenance sample handling components. Protea offers both Infra-Red (IR) and Ultra Violet (UV) in-situ gas analysers.

Emissions DAHS

Data Acquisition and Handling Systems (DAHS) for Emissions Data is a critical component of a Continuous Emissions Monitoring system. As well as providing the approved analyser to measure emissions, Protea can provide Emissions Reporting Software and data collection Hardware with the installation that will combine gas readings with those of dust, flow, temperature and process conditions to report emissions to the level of detail and confidence that legislation requires.
