The acquisition of SpectraSensors has strengthened Endress+Hauser’s analysis business – and given access to revolutionary laser technology. We can now offer precise measurement of substances that can have a devastating effect on the integrity of gas pipelines.
Moisture and hydrogen sulphide can cause internal corrosion in natural gas pipelines. Therefore, in order to avoid pipeline ruptures and to comply with quality specifications, gas companies must measure such parameters. Yet traditional infrared analysers can suffer from false positives or cross-interferences from other contaminants present in natural gas streams.
SpectraSensors SS2100i-1 process gas analysers are exceptionally reliable for measuring trace gas components using tunable diode laser (TDL) technology. TDL absorption spectroscopy is a high-resolution infrared technique that enables the measurement of specific gases with precision while avoiding interferences. With ATEX and IECEx approval, the analysers are ideal for use at custody transfer points to measure moisture and hydrogen sulfide on export metering packages, as well as in natural gas processing plants to measure hydrogen sulfide on amine scrubber outlets or moisture on desiccant dryer outlets.
Proven reliability Tunable diode laser absorption spectroscopy was introduced to hydrocarbon applications by SpectraSensors more than a decade ago. The rugged nature of these laser-based analysers has allowed them to be used in natural gas pipelines with very little maintenance, no interference and with no detrimental effects from contaminants such as glycol, methanol, amine or moisture slugs. Since its inception, this technology has demonstrated its reliability in thousands of installations worldwide.
Validation SpectraSensors TDL analysers require no calibration in the field and the factory calibration is stable for the life of the analyser. However, a process operator will want to check that the analyser is performing in the field. To enable this the analyser systems are equipped with validation gas connections to accept gas blends of moisture or hydrogen sulfide. Additionally, automated validation options are available for triggering validations on a routine basis
