High accuracy gas analytical solution for process quality improvement and fast ROI in olefin plants

SpectraSensors tunable diode laser absorption spectroscopy (TDLAS) analyzers measure.

Tunable diode laser absorption spectroscopy (TDLAS)

SpectraSensors' tunable diode laser absorption spectroscopy (TDLAS) analyzers perform on-line, real-time measurements of C2H2, NH3, H2O, H2S, and CO2 in olefins production plants to improve process efficiency and help deliver high purity ethylene and propylene for downstream polymer production.    

Typical applications

  • Acetylene C2,H2, in ethylene

  • Ammonia NH3 in ethylene

  • H2O in ethylene

  • H2O in propylene

  • H2S and CO2 in Caustic Wash Tower Inlet
