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 100 ppmv.

Traditional approach

High levels of solid and liquid contaminants and varying concentrations (glycol, methanol, compressor oil, sulfur compounds) challenge measurements of moisture

  • 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): The 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 0-5000 ppmv

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

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

Unique benefit

  • 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
