Ambient air quality monitoring at airports

Monitoring the air quality at and around airports can be done for several reasons. It may be a question of monitoring the pollutants that employees and passengers are exposed to, but it may also be a matter of studying the contribution of aviation and ground traffic to pollution. Regardless of purpose, monitoring can be a challenge. The location of the measurement site must be representative. A large number of gaseous components need to be monitored with high accuracy and high ...

Air quality monitoring solutions for monitoring of SO2 scrubbers sector

Air quality monitoring solutions for monitoring of SO2 scrubbers sector

In recent years, increasingly strict requirements have been introduced to minimise sulfur emissions from shipping. One way to comply is to run the ships with low-sulfur oil, but this can be expensive. An alternative that makes it possible to continue using high-sulfur oil as fuel is to install SO2 scrubbers that clean the flue gases to the same level as if the ships were fueled with low-sulfur oil. However, the scrubbers must be monitored by measuring the ratio of SO2 to CO2 concentrations. Here, OPSIS has a ...

Ambient air quality monitoring solutions for urban air quality monitoring

There can be several purposes for monitoring the air quality in an urban area. If the aim is to assess what the residents are exposed to in the worst case, a so-called street-level monitoring is carried out. If the aim is to monitor the general levels of air pollution and follow up long-term trends, you should instead monitor further away from the busiest roads, for example at roof level. ...

Ambient air quality monitoring solutions for benzene monitoring

Benzene monitoring around refineries: Measuring benzene emissions from a refinery plant can be challenging, but OPSIS makes it easy. Benzene is a liquid hydrocarbon that evaporates rapidly when exposed to ambient air. It is one of the more common substances used in the chemical industry and is particularly prevalent at refineries and similar operations. Benzene causes cancer and is therefore subject to ...

Continuous emissions monitoring solutions for chemical industry

'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 ...

Continuous emissions monitoring solutions for sulfuric acid production plants

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 ...
