NASA Based Technology Keeps Contaminants Out of Gas Pipelines

Reliable NASA-based gas analyzer technology keeps natural gas producers aware of moisture content before entering El Paso Natural Gas Company Pipeline – helping producers avoid expensive shut-ins


Improve process control in gas plants using tunable diode laser spectroscopy

Tunable diode laser (TDL)-based analyzers (Fig. 1) are increasingly being used in these “pain-point” analytical applications to measure contaminants reliably while reducing maintenance and operating costs.   TDL absorption spectroscopy uses a laser mounted behind a window that protects it from the wear and tear of caustic gas contents while enabling the analyzer to accurately and quickly read varying gas concentrations. The laser does not come into contact with the gas and calibration does not change or drift over time.   Dependable H2O analysis. Impurities, such as H2O and corrosive acids found in many gas streams, are the nemesis of conventional sensors that are directly exposed to the gas stream and those harmful elements.  Over time—and sometimes within a few weeks—those probes become damaged and inaccurate, resulting in costly repair or replacement. In the meantime, corrosion and contamination from problematic …


TDL Technology Promises Improved Process Control in Gas Plants

Ultra-fast and highly accurate, a new Tunable Diode Laser analyzer technology is replacing conventional sensors at refineries and gas processors, saving on maintenance while providing enhanced control over process integrity.
