Gas processing
Non-contact, accurate measurement of natural gas contaminants
Monitoring contaminants is critical for process optimisation and gas quality. High resolution SpectraSensors TDL technology eliminates errors due to interferences associated with other spectroscopic approaches.
Hydrogen sulfide H2S in amine scrubber outlet
One of the first steps in a gas plant is the reduction of acid gas components. Measuring ranges starting from 0 to 10ppmv for H2S and from 0 to 10ppmv for H2O.
The traditional approach
Lead acetate tape analysers work but have high maintenance requirements to replace and dispose of the tapes in an environmentally safe manner.
Online gas chromatographs take 3–6 minutes between measurement updates and do not sense rapid changes. OPEX are high due to consumption of carrier gas and flame fuel cylinder gases.
Broadband UV light sources and narrow band pass filters are prone to interferences from changing background concentration.
Our solution
High resolution SpectraSensors TDLAS technology eliminates errors due to interferences encountered with other spectroscopic techniques.
