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 ...

The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few ...

SO2 (sulfur dioxide) is measured in a number of applications. SO2 is used as a food grade preservative and must be regulated in accordance with government-set criteria to be safe for consumers. It is also measured in fuel exhaust to control for environmental pollution and in cement plants for process ...

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 ...

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 ...

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 ...

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 ...

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. ...

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 ...

'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 ...

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 ...

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 ...
