New solution in H2S measurement in Y-Grade NGL fractionation

SpectraSensors TDL Analyzer offers improved method for critical measurement of hydrogen sulfide

The Tunable Diode Laser technology eliminates errors faced in traditional methods used for the critical measurement of Hydrogen Sulfide in NGL fractionation plants. The TDL analyzers are low maintenance and has low cost of ownership.

NGL Fractionation process

Benefits At a Glance

  • Fast, high sensitivity measurement of hydrogen sulfide

  • Tunable Diode Laser and Detector are isolated, protected from the process gas and contaminants

  • Low cost of ownership - no lead acetate tape or GC carrier and detector gasses to buy

  • TDL differential spectroscopy technology avoids interference from changes in background compounds

The Challenge

Issues with traditional measurements

Lead acetate paper analyzers have been used but they require frequent replacement of the tape and disposal of the tape is problematic because it contains lead. Gas Chromatographs(GC) equipped with Flame Photometric Detectors (FPD) are also used. FPD's experience coking and flame-outs with hydrocarbon streams and are maintenance intensive. GC's have relatively long measurement cycle time

Our Solution

The SpectraSensors TDL analyzer offers a new solution for the critical measurement of hydrogen sulfide. There are no cylinder gasses to replace, so the analyzer is very low maintenance and has low cost of ownership over the life span of the analyzer. The high resolution TDL technology eliminates errors from interferences that have hampered other spectrometric approaches. Analysis time with Tunable Diode Laser technology is fast with results updates in seconds.
