Natural gas

Reliable and robust gas analysis solutions to continuously ensure pipeline safety

Monitoring contaminants, e.g. H2S, H2O, to protect pipelines from corrosion and blockage by hydrate formation and to assure quality specifications for custody transfer.

Moisture H2O in natural gas pipelines

Low moisture content is critical to meet quality specifications and to protect pipelines from corrosion. Measuring range starting from 0 to 100ppmv.

The traditional approach

High levels of solid and liquid contaminants and varying concentrations (glycol, methanol, compressor oil, sulphur compounds) can cause issues with moisture measurement.

  • Sensors relying on the adsorption onto sensitive surfaces have wet-up or dry-down delays.

  • Contaminants may destroy some moisture sensors.

  • Cross-interference affects moisture readings.

  • Al2O3 sensors are slow and subject to other components in natural gas.

Our solution

SpectraSensors' tunable diode laser absorption spectroscopy (TDLAS) is a rugged solution used in natural gas pipelines with very little maintenance, no interference and with no detrimental effects from glycol, methanol, amines, H2S, moisture slugs, etc.

Typical analytes and measuring ranges

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

  • Analyte: H2O - Range: 0-100 to 0-2500ppmv

  • Analyte: CO2 - Range: 0-5 to 0-20%

The benefits:

  • Accurate, non-contact measurement with no wet-up or dry-down delays in real-time.

  • Calibration-free, no routine maintenance.

  • Independent from glycol, methanol or amine.

  • No consumables.

Applications

  • Monitoring contaminants, e.g. H2S, H2O, to protect pipelines from corrosion and blockage.
  • Reliable and robust gas analysis solutions to continuously ensure pipeline safety.
