Emissions Monitoring

Continuous Emissions and Periodic Emissions Monitoring Systems

Protea has been at the forefront of emissions monitoring systems for 20 years, as both a manufacture 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 requirements.

Stationary Source Emissions – 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.

Stationary Source Emissions – 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.

Marine Emissions

The International Maritime Organization (IMO) sets pollution limitation on vessels, being documented in MARPOL 73/78. In particular, this regulation governs emissions of NOx and SOx gas species being emitted from ships engines, with NOx being linked to the diesel engine maximum speed and SOx the sulphur content of the fuel.

Marine emissions requires simple to install and operate Continuous Emissions Analysers and Protea’s in-situ marine analysers have been used for many years on ships. Not only to report emissions but, also control scrubbers on-board vessels. With stricter limits being imposed, particularly for SO2, the CEM technology used has to improve to give the performance needed.
