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

​
