Water Measurements in Dry LNG Feed Gas

 
SpectraSensors TDL analyzer is the ideal solution for monitoring moisture in dry LNG feed gas. Its noncontact laser and detector is impervious to damage from contaminants. Tunable Diode Laser technology means that measurement interferences from other infrared absorbing compounds are avoided. There are no wet-up or dry-down delays, resulting in fast updates even when the concentration changes dramatically. Only SpectraSensors employs Differential Spectroscopy, which incorporates a dryer using metal getter technology to subtract the spectrum of the dry gas from the wet spectrum. This allows the analyzer to measure streams whose background gas composition may change.
