Threats and Integrity Management -- Pipeline Testing, Analysis and Repair

The project developed and field-tested a portable, low-cost instrument for the measurement of hydrogen sulfites and mercaptans, which are found in natural gas, renewable natural gas, biogas, and landfill gas. The instrument allows the detection and measurement of such compounds at the part per billion (ppb) level, serving as an artificial human nose. A follow-up phase will be needed to build a market-ready instrument and commercialize it.

This technology makes it possible to detect ppb-level measurements of mercaptans in the field, where it is impractical to use and transport costly benchtop, laboratory-grade gas chromatograph instruments.

Increased Safety - This technology allows for highly sensitive, accurate leak detection in the field so that timely repairs can be made to ensure safe, reliable operation.

Reduced Operations Cost - This proactive approach also results in lower costs to the operator.

Greater Reliability -
