'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 ...

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 ...

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 ...

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 ...

Ships: floating fossil power plants with emissions to air as for land-based power plants. The UN agency IMO has issued rules (the MARPOL convention) on the limitation of ship emissions into the ambient air. Among other things, nitrogen oxides (NOX) and sulfur (sulfur dioxide, SO2) are regulated. OPSIS has the instruments to monitor the ...

Monitoring real emissions from vehicles with combustion engines. Emissions from vehicles powered by fossil fuels have traditionally been tested in laboratories, but the results rarely reflect reality. Therefore, rules regarding "Real Driving Emissions" (RDE) have been added. The emissions are then measured correctly in a real environment and during real driving. OPSIS offers an RDE monitoring system based on the well-proven DOAS ...

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 ...

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. ...

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 ...

Monitoring in raw gas places high demands on the instruments. The temperatures are high and the gases are often reactive. There may also be high dust levels. In order to control flue gas cleaning, the monitoring systems must also be able to react in near real time.
