Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
Requirements for monitoring emissions to air are governed by EU/UK legislation and are implemented in the form of a permit by the Environment Agency or local authority. The Dr Foedisch muti-component gas analysers continuously extract a gas sample from the exhaust stream via a stack probe into the analyser cabinet.
Both hot and cold gas systems are available, please contact us to discuss which system best suits your requirements.
Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.
Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.
The Environics Series Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty years. They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M.
Our systems are custom built, computerized, mass flow controller based gas calibration systems which allow you to dilute a single high concentration cylinder of span gas to low levels for the calibration of gas analyzers.
The real-time monitoring of odorous gases or more classical pollutants emitted by industrial sites (wastewater treatment plants, refineries, landfills, etc.) appears nowadays as a requirement, in order to optimize the site process and operations, or communicate towards the neighborhoods and local public bodies.
While emissions can be measured directly at the source (in the stack, exhaust, etc.), ambient air measurement all around the sites provides a better accuracy and anticipate pollution episodes. This is why...
Opsis provides state-of-the-art monitoring equipment, fully meeting the high standards of monitoring performance and reliability that the cement industry requires. The Opsis in situ systems are designed to withstand environments with high particulate levels and high temperatures.
Process control and emission monitoring in a waste to energy plant is a challenge. A large number of gaseous components need to be measured with high accuracy. Almost 100% uptime is required and the monitoring system needs to be easy to maintain and fast to calibrate.
Typical supported applications are industrial emission monitoring and gas manufacturing control. Focuses on medium NOx, NOx-related and multigas-concentrations up to 5’000 ppm where flexibility is a central requirement. Parameters included are NO, NO2, NOx, NH3, NOx-amines, O2 and CO2. Typical supported applications are industrial emission monitoring and gas manufacturing control.
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.
Protea has used our VOC gas analysers in many projects requiring the monitoring of complex mixes of VOCs. In the chemical and pharmaceutical industry, VOC abatement plants such as scrubbers and carbon-bed systems are typical installations where the use of Protea analysers and our VOC analysis expertise have proved valuable to plant operators. They prove a very powerful and flexible tool in both process gas measurements and VOC emissions monitoring. In the laboratory, Protea can deliver instruments with all the...
Upstream and downstream activities in the industry require a variety of gas analysis capabilities that are well served by MIRICO’s laser-based technology. Our unique Laser Dispersion Spectroscopy technique is a versatile technology that can be deployed in an open-path configuration for the measurement of methane for health & safety monitoring. When combined with an array of reflectors, a single light source can cover a complex route in excess of 1 km, a considerably larger distance than comparable...
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...
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...
The recent COP 21 meeting reexposed the need for global coordination to monitor Green House Gases (GHG) as well as emissions of ChloroFluoroCarbons (CFC). Networks of sensors have been deployed over the Earth to measure concentration of gases such as methane, carbon monoxide, ethane, carbon dioxide, nitrous oxide, nitrogen oxide and dioxide (NOx)… Such task requires instrument with not only ultra high accuracy but also ultra high precision. Our QCNose Instruments have been designed for such operations...
A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.
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
An examination of the literature shows that the Tekran 2537 is the choice for measurements of mercury aboard research aircraft. Several research groups in Europe and North America have used the Tekran 2537 on an aircraft platform for point source plume studies, free troposphere speciation characterization, vertical profiles, characterizing emission source regions and even the stratosphere (http://www.caribic-atmospheric.com/instrum/hg.html). Normally, the Tekran 2537 requires simple modifications for aircraft...
