Renewable energy plants are expanding and being developed at a significant rate in North America and throughout the world. In the United States, the Clean Air Act for reformulated gasoline (RFG) mandates a 2wt.% oxygen requirement, driving the demand for more production. Ethanol is the most viable additive because it is a clean-burning fuel produced from renewable, domestic biomass sources. However, the production of these fuels can result in unacceptable levels of volatile organic compounds (VOCs), carbon...
Most industrial processes have dust collectors of some form or other, the most popular being filter bag houses. Very few of these are covered by regulation other than to have a broken bag detector to prevent nuisance dusts escaping and creating a local nuisance. The CODEL StakGard is a low cost Tribo-electric monitor that directly measures mass particulate concentration by sensing the frictional charge created when particles collide with a conductor. The advanced electronics of the StakGard detect this signal and...
There is a requirement for many small boiler operators to monitor Opacity to determine the smoke density emitted from the boiler. On small boilers we recommend the DCEM 1001 Opacity monitor; this simple, low cost monitor has high efficiency air purges use compressed air to ensure that optical surfaces are virtually free of dust or debris contamination. This ensures minimal maintenance is required on the sensors.
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...
For large combustion plants and power plants we offer the DCEM 2100 particulate monitor. This monitor is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It offers outputs in Transmission, Opacity and mg/m3 (when calibrated against a Standard Reference Method). The DCEM 2100 offers real-time zero and span calibration and an efficient air purge system to prevent optical contamination.
According to US EPA IO - 3.3 standard method of heavy metals, PMMS – 5000 uses XRF nondestructive testing technology and atmospheric automatic enrichment technology to realize the accurate measurement of atmosphere heavy metals such as lead, mercury, cadmium, chromium, arsenic, etc. It is widely used in environmental air quality monitoring places such as industrial pollution area, residential area, city, etc.
Researchers and Engineers utilize HI-Q air sampling equipment and systems for analyzing and investigating environments around the world. Data collected by HI-Q air sampling systems have provided critical information in the identification and prevention of pollution. HI-Q offers a line of high volume (TSP-Type) air sampling systems for data collection in perimeter monitoring & industrial emissions monitoring applications.
In some countries they do not allow tunnel atmosphere monitors to be mounted on the tunnel wall; also, where there is a single bore it is very difficult to gain access for maintenance purposes. The TunnelTech 400 series are extractive gaseous pollutant and visibility monitors and extract a gas and dust sample from the tunnel bore and carry to a remote analyser. This allows maintenance to take place without affecting tunnel traffic flow.
For processes where plastics are molded or extruded (as evidenced by a “hazy” exhaust plume at the stack) scrubbers are used to treat the sub-micron particulates and oil mists generated. Certain other processes (e.g. Fiberglass Reinforced Plastic equipment fabrication) emit VOCs that can be captured with absorption.
Several industries face problems from dust released during product transportation or processing. This is the case of the Textile, Wood Processing, Mining, Ink Manufacturing and other industries. Frequently, in order to maintain an appropriate level of particles suspended in the air (usually measured in Parts per Million by Volume), dust is extracted with air in strategically positioned caption points and typically recovered in cyclones or in bag filters.
The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it is...
The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.
With the application of air quality PM2.5 standards, people have a clear understanding and attention on ambient air quality, countries also present clear requirements and control objectives. Due to the speeding up of development process of cities construction in recent years, unceasing expands of the urban area and population scale, sustained growth of energy demand, motor vehicle ownership, various construction projects, the situation of urban air quality improvement work is more severe.
The production of construction materials has a long tradition. Thus the production processes in some places have not yet been adapted in all areas to the present state of art. With our measuring systems we are improving and modernizing production processes in cement and mineral plants as well as in the construction material chemistry. Continuous mass flow measurement, online moisture measurement and dust monitoring systems are used frequently in this sector.
Zeta potential is a parameter characterizing electrochemical equilibrium at interfaces. It depends on the properties of both the surface and the surrounding liquid. It plays an important role in the theory of aggregative stability, also known as DLVO theo

Acoustic theory for heterogeneous system should yield a relationship between some measured macroscopic acoustic properties, such as sound speed, attenuation, acoustic impedance, angular dependence of the scattered sound, etc., and some microscopic charact
The Opsis gas monitoring system is designed for monitoring in stacks and gas ducts in chemical industries, both in order to increase plant efficiency and to monitor emissions. The Opsis systems have been internationally approved by e.g. the German TÜV and the U.S. EPA.
Customized solutions – from development to customer service! The carbon dust required for the production of steel can be continuously measured directly in the conveyor lance by specially developed measuring systems of ENVEA - SWR. With this technique thermal imbalances in blast furnace can be avoided, and it can be directly reacted to production stops.
