Gas processing

Non-contact and accurate measuring of natural gas contaminants

Monitoring contaminants is critical for process optimization and gas quality.

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 10 ppmv for H2S and from 0 to 10 ppmv for H2O.

Traditional approach

  • Lead acetate tape analyzers work but have high maintenance requirements to replace and dispose of the tapes in an environmentally safe manner

  • On-line 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.

Typical analytes and measuring ranges

  • Analyte: H2S - Range: 0-10 to 0-5000 ppmv

  • Analyte: H2O - Range: 0-10 ppmv

  • Analyte: CO2 - Range: 0-100 ppmv to 0-5%

Unique benefits

  • Differential spectroscopy provides accurate low-level measurements in complex hydrocarbon streams

  • Factory calibration ensures stable, long-term in-field operation

  • Faster response protects pipelines from H2S contamination

  • Monitoring contaminants is critical for process optimization and gas quality
