Liquefied natural gas (LNG)

Real-time measurement of contaminants down to trace levels

Monitoring impurities in gas feed to the cold box to ensure reliable liquefaction and on-time shipments

Moisture H2O in molecular sieve outlet

Gas moisture concentration at outlet of desiccant dryers to prevent freeze-up of liquefaction train. Measuring range starting from 0 to 2 ppmv.

Traditional approach

  • Electrochemical cells are affected by trace hydrocarbons and other contaminants requiring frequent replacement

  • Quartz crystal moisture balances are sensitive to contaminants and have high OPEX

Our solution

SpectraSensors' non-contact laser is immune to damage and has with no wet-up or dry-down delays even when the concentration changes dramatically

Typical analytes and measuring ranges

  • Analyte: H2S - Range: 0-10 ppmv

  • Analyte: H2O - Range: 0-2 to 0-10 ppmv

  • Analyte: CO2 - Range: 0-100 ppmv

Unique benefit

  • Reliable trace-level (sub-ppm) measurement with “Differential Spectroscopy”

  • Periodic self-validation with an integral, internal permeation tube avoids downstream up-set

  • Exceptionally fast response to detect moisture breakthrough

Applications

Monitoring contaminants is critical for process optimization and gas quality

  • Guided wave radar in refineries

    Refinery Application

    Are you experiencing deviation alarms in your high pressure process vessels? In many high pressure vessels, redundant level technologies are employed to provide multiple level indications for safety.

  • Functional Safety in practice by Endress+Hauser

    Functional Safety in practice

    Investments in functional safety, and thus in measures to avoid accidental and systematic errors, are very moderate if one relies on instruments developed according to IEC 61508.
