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 absorption 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.
