Blue Ocean Nova On-line Proces Analyzers for Gases

Gas cell for refinery gases


Specific requirements exist for process interfaces in refining environments with regards to ambient temperature and pressure, as well as compliance with explosion proof requirments for hazardous areas.






Hydrogen sulfide (H2S)

H2S_gasHydrogen sulfide (H2S) is a crucial process parameter in the processing of oil, natural gas, waste and sewage treatment. As it is poisonous, corrosive and explosive, it is of paramount importance and mandated by regulatory bodies to monitor the concentration levels in real-time during any process.

Blue Ocean Nova’s H2S sensor families for liquids (TRITON) and gases (BOREAS) are able to analyze H2S concentrations in water as well as gases in concentrations in the single digit ppm range, using multivariate analysis in the UV and MIR spectral range, combined with patented measurement interfaces to withstand the corrosive nature of the analyte.


Gas cell for biogas


This gas cell has been specifically developed for applications in biogas plants. Path length optimization to 200 mm enables continuous inline analysis of methan, H2S and CO2 in realtime. Due to the omnipresence of H2S in biogas, the materials with product contact have to be sufficiently resiliant, to withstand the corrosive nature of H2S.





Without available and appropriate measurement techniques, biogas plants are often run below capacity, in order to avoid instabilities in the fermentation process.

BON’s sensors for biogas are matching the rugged requirements for analytical measurement equipment for inline deployment with regards to gaskets, window material and the robustness of the stainless steel blend used for the probe shafts, which are for ease of maintenance, easily interchangeable.
