Moisture in natural gas
In the past, electro-chemical sensors were used which rely on the adsorption of water onto a sensitive surface and require direct contact with the natural gas. In practice, wetted sensors are adversely affected by natural gas components such as H2S and various liquids, which cause errors, interferences, and failures.
Tunable diode laser absorption spectroscopy (TDLAS) was introduced to the natural gas industry by SpectraSensors more than 15 years ago. The rugged nature of these laser-based analyzers allows them to be used in natural gas pipelines with very little maintenance, no interference, and with no detrimental effects from glycol, methanol, amine, H2S, moisture slugs, etc.
Since inception, SpectraSensors has demonstrated reliability in thousands of installations worldwide. As the natural gas industry evolves with an ever-increasing footprint of unconventional gas, SpectraSensors continues to adapt and lead with the most robust lasers, optics, algorithms and expertise in the field of laser-based gas quality measurement.
