Particulate monitoring for continuous emissions

by DynOptic Systems Ltd     based in Brackley, UNITED KINGDOM

With the advent of specific process emission limits being defined, continuous particulate monitoring has become a regulatory requirement for many industries. smoke stack #1Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere. There is no known method of continuously measuring particulate concentration by direct measurement and therefore, all continuous particulate measurement methods are inferential. Each method involves the measurement of a parameter related to particulate concentration and then requires a calibration to be determined to convert the measured value into one of particulate mass concentration.

Air monitoring for laboratories

by GE Healthcare UK Limited     based in Little Chalfont, UNITED KINGDOM

Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.

Common air monitoring applications include:

  • Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
  • Asbestos sampling and analysis

Indoor Air Quality Monitoring

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide (CO2), carbon monoxide (CO) and volatile organic compounds to particulates, humidity and bacteria such as legionella. CO2 is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying the building. CO2 production is a function of the number, size and activity levels of the people present in the building. Local concentrations can therefore vary dramatically – for example when a meeting room is occupied, or while workers are on lunch or coffee breaks. Excess CO2 levels can lead to tiredness and a lack of concentration and can contribute to the symptoms of Sick Building Syndrome such as headaches, eye, nose and throat irritation, itchy skin and nausea.

Roadside monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution.

Gas monitoring instruments and systems for engine emissions measurements

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a dynamometer laboratory, or the portable version can be used for roadside tests.

Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

by Chromatotec Group     based in Val de Virvée, FRANCE

It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase. The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.

Carbon Dioxide Monitoring for Indoor Air Quality

Laboratory Weighing - Filter Weighing

by Mettler - Toledo Int. Inc     based in Greifensee, SWITZERLAND

Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

Marine emissions monitoring

by DynOptic Systems Ltd     based in Brackley, UNITED KINGDOM

In recent years, new regulations have been introduced governing emissions from ships. With the International Maritime Organization (IMO) adopting Annex VI of MARPOL designed to limit sulphur oxides (SOx), nitrous oxides (NOx) and particulate matter emissions, as well as introducing emission control areas (ECAs) to reduce emissions of those air pollutants further in designated sea areas, ship owners/operators can face hefty fines for failing to meet these new requirements on the “polluter pays” principle.

Traffic Emissions Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution. Roadside pollution concentrations can change quickly as types and volume of traffic changes and so instrumentation used must be able to cope with these rapidly changing conditions. Ecotech has established a wide variety of roadside monitoring stations incorporated both into large walk-in style shelters to compact monitoring shelters. Our solutions can be tailored to your needs. Ecotech`s compact solution uses a compact monitoring shelter fitted out with a variety of analyzers and particulate monitors. These analyzers offer fast response, minimal maintenance and are widely used for roadside monitoring.

Independent particle characterization services for environmental industries

by Particle Technology Labs     based in Downers Grove, ILLINOIS (USA)

Particle size, particle concentration and other physical characterization analyses are critical to many environmental applications. Regulatory agencies in the environmental sphere demand strict compliance to standards and discharge regulations. Physical testing of samples for parameters such as particle size and concentration can give insight to the process control engineer on how effective and compliant a discharge handling system is operating. Particulate loading from both air emissions and waste water discharge are monitored in many industry sectors and PTL testing provides valuable supporting data in this monitoring process.
