The OXY5500 oxygen analyzer is a compact, stand-alone, single channel analyzer that uses quenched fluorescence (QF) technology to reliably measure oxygen in natural gas and gas processing applications. A sensor probe is inserted into the process stream and is connected to the controller by an optical fiber. Featuring an LCD display and built-in data logger, the OXY5500 also has full sample conditioning systems available as well as software for a PC interface.
Natural gas quality measurements in production, storage, transportation, and distribution
Monitoring in natural gas, upstream of production and gathering sites
Measurable range from ppm levels to 0-20% O2
Trace measurements as low as 0-10 ppmv oxygen in hydrogen for electrolyzer applications
Ideal for CCUS applications since optical oxygen measurement is unaffected by CO2 or H2S in the process
Benefits
Easy to navigate display and menu
Small optical sensor with no membrane or consumable chemicals
Optical measurement with fast, continuous response
Check out the findings from the GERG report on the use of a Raman Rxn4 analyzer and Raman Rxn-41 cryogenic probe for the reliable chemical composition measurement in LNG custody transfer applications.
