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. ...

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 certified, cost-effective, and reliable ...

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 ...

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. However, these are no problems for OPSIS non-contact monitoring systems, which work excellently in these circumstances, with high availability and low operating ...

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. ...

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 ...

'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 ...
