The almost closed environment means that high levels of air pollution often occur inside the tunnels. The limit values for the pollutants are often higher in tunnels than in open ambient air because the exposure time is normally limited, but it may still be necessary to monitor that the limit values are not exceeded. Traffic tunnels often have to be provided with ventilation to keep the levels of air pollutants below the applicable limit values. To save energy, however, it is common not to operate the fans more ...

Air pollution at regional and national scales. It is important to monitor air pollution where many people stay, i.e. in cities and especially at street level. In order to better understand where the pollution comes from, a so-called background monitoring may also be needed. Then the monitoring station is placed in the countryside, at a great distance from obvious sources of the ...

Process monitoring and monitoring of emissions from aluminium smelters can be a challenge due to high concentrations of for example hydrogen fluoride (HF) and dust. The use of sampling systems in such environments requires a lot of maintenance and is therefore costly. Such systems can also be unreliable. OPSIS offers better ...

A challenging environment for monitoring instruments. Process control and emissions monitoring at a fertilizer plant can be difficult due to aggressive process gases in high concentrations, sometimes at high temperatures and pressures. Use of extractive monitoring systems in such an environment requires a lot of maintenance and the instruments are prone to malfunction. However, unlike extractive systems, OPSIS non-contact monitoring technology has no problem handling these ...

Various types of sulfur compounds often arise during the production of paper pulp. There are emission limits and monitoring requirements, often expressed as total reduced sulfur, TRS. TRS includes hydrogen sulfide, H2S, and the sulfur compounds methyl mercaptan, dimethyl sulfide, and dimethyl disulfide. OPSIS offers systems to monitor both H2S and ...

Challenging conditions for gas analysis at waste-to-energy facilities. Process and emissions monitoring at waste-to-energy plants or plain waste incineration plants can be a challenge. A large number of gas components need to be monitored with high accuracy. The flue gas is often aggressive and has high dust and moisture content. Close to 100% uptime is required, the monitoring system must be easy to maintain, and it must be able to be calibrated quickly. The OPSIS monitoring system handles all these challenges ...

Port environments can be particularly exposed to air pollution, both in gaseous form and as particles. The ships are an obvious source, but both activities related to the unloading and loading of goods and land traffic to and from the ports can also contribute. Monitoring the concentration of air pollutants can be done both in order to monitor the environment in general and to map the sources. In the case of emissions from ships, it may be of particular interest to monitor sulfur dioxide (SO2) levels near the ...

'Chemical industry' can comprise many types of industries, for example refineries, paper mills, fertilizer production, and sulfuric acid plants. Each individual industry may have its own special needs and special environments, but there are also many common factors. Regardless, process control and emissions monitoring at chemical plants can be challenging due to for example toxic, aggressive and/or explosive gases, and high temperatures. The use of extractive systems in such environments requires a lot of ...

Process control and emissions monitoring in a mineral wool plant is a challenge due to the presence of phenol and formaldehyde. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS DOAS system is different and provides plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the ...

A tough environment requires toughened monitoring equipment. Process monitoring at a sulfuric acid plant requires good and reliable detection of, among other things, sulfur dioxide (SO2) in gas phase. This can be a challenge due to high concentrations of SO2, high temperatures, and high pressure. Monitoring may be needed at several locations in the process where SO2 concentrations may vary from a few mg/m3 to several percent by volume. Not all monitoring systems can handle these conditions and those that do ...

Monitoring elemental and total mercury. There is a risk of toxic mercury being released into the air at for example waste incineration and cement production, and from coal-fired thermal power plants. To prevent this, there are requirements for flue gas treatment with low emission limits, and requirements for monitoring of the levels not exceeding these limits. OPSIS offers well-proven and certified systems for the required monitoring of mercury levels, both elemental mercury and the mercury compounds collectively ...
