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 ppm_v.

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
