Gases & Industries

CH₄ is a potent greenhouse gas that contributes to climate change. One of the targets of the oil/gas industry is to reduce these emissions into the atmosphere.

In challenging applications, like complex piping infrastructure or remote areas, gas cloud imaging technology can increase safety. It provides 24/7 monitoring of gas concentration and emission rates in Ex zones in real-time. Operators can view multicolor images for different concentration levels with thermal imaging technology.

VHP (vapourized hydrogen peroxide) is generated by actively evaporating liquid hydrogen peroxide solution. The vapour is then released or injected into a confined space. A high concentration is needed to create a high decontamination rate of microorganisms. VHP is rated as a hazardous substance for humans with a defined workplace limit value. Safety targets are:

• Workplace safety
• Leak detection
• Release for safe entry and access cycle parameter control
• Emission monitoring after filter and scrubber

The gas is found in the production of crude oil, LNG or wastewater plants. Primarily electrochemical sensors are used to detect H2S concentration in the ppm range. A reliable gas detection system is necessary to protect employees at site, often supported with sensor alive field tool, which assists the sensor by automatically starting the sensor test procedure to confirm the sensor’s functionality. The sensor tests are reported to the safety control unit so that the user is always informed about the status of the system.

In environments where oxygen levels can fluctuate, there are two significant risks to consider: oxygen deficiency and oxygen enrichment. An oxygen detector continuously monitors oxygen levels and provides timely alerts to ensure the safety of individuals in oxygen-deficient environments. On the other hand, oxygen enrichment poses the risk of increased flammability and fire hazards. Organisations can also detect excessive oxygen levels and take immediate action to prevent fire incidents by employing the same oxygen detector. These detectors are critical in maintaining a safe and balanced oxygen environment, safeguarding personnel from oxygen deficiency and enrichment risks.

It is a strongly pungent smelling, colourless, water-soluble toxic gas that irritates tears and has a suffocating effect. Widely used as cooling medium, as a feedstock for fertilizer production or as hydrogen carrier. All industries are using it: Widely used in pharmceutical-, food & beverage-the chemical industry and in cleantech applications like on NH₃ carrier ships. Normally the detection requirements are in range of 20- 300 ppm. At explosive concentrations around  15 Vol-% a catalytic detector is used to protect the environment against explosions.

One of the most common toxic gases is carbon dioxide, seen in  food and beverage industries or CCUS processes. In case of leakages there is a high risk to be harmed significantly entering the CO₂ gas cloud due to the lack of oxygen. The risk can be lowered, today modern gas detectors can detect in a highly specific manner CO₂, with IR sensing technology.
