Kaiser Raman Pilot-E Probe for LNG

Optimized design for in situ process analyses of cryogenic liquids

The design of the Pilot-E probe for LNG has been optimized for in situ process analyses of cryogenic liquids.  Analyzing LNG as a cryogenic liquid eliminates the errors associated with sampling systems such as vaporizers, which are typically required with traditional process analyzers, resulting in  greatly improved certainty of the value of LNG transacted during custody transfer.

The Pilot-E probes can be supplied, marked, and certified to the ATEX directive, North American (CSA) hazard area, or IECEx safety requirements. The combination of the Pilot-E probe for LNG and Kaiser Raman analyzers (Raman Rxn4 for LNG, Optograf Analyzer) yields a powerful process analytical tool for in situ composition analysis of LNG and mixed refrigerants using quantitative Raman spectral analysis.
