Field of application
Using patented tunable diode laser absorption spectroscopy (TDLAS) technology, the SS2100 gas analyzer measures specific gases (H2O, CO2, and H2S) with precision while avoiding interferences that are common with traditional infrared analyzers. The SS2100 analyzer requires little maintenance and does not need recalibration or periodic replacement parts.
Gas analysis: ppb level measurement of H2O, ppm level measurement of H2O, H2S, and CO2, and percent (%) level measurement of H2S and CO2
Natural gas: production, storage, transportation, distribution
Refinery: hydrogen recycle, catalytic reforming, flaring, cracking
Gas processing: fractionation, sour/acid gas removal
LNG: liquefication, custody transfer
Petrochemical: cracking, caustic wash tower
CCUS: measure trace H2S and H2O in 100% CO2
Benefits
Accurate, real-time measurements
Low cost of ownership, no consumables and virtually maintenance-free and reliable in harsh environments
Available to measure up to 3 analytes in one unit (2-packs or 3-packs)
Provides measurements not hampered by wet-up (absorption) or dry-down (desorption)
Dependable with greater repeatability than surface-based sensors
Analog and serial outputs for remote monitoring
Available for following measurements: H2O, CO2, H2S
