LIQUEFIED NATURAL GAS
Liquefied Natural Gas
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
