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 10ppm_v for H₂S and from 0 to 10ppm_v 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.
