Case study: Ensuring confidence in liquid natural gas composition

EffecTech is pleased to announce the publication of a new case study by EURAMET about EffecTech’s ISO 17025 accredited liquefier for the calibration of spectroscopic instruments, such as Raman, for measuring liquefied natural gas (LNG).

Since natural gas emits fewer lower greenhouse gases than other fossil fuels, it is a key transition fuel in the global move towards Net Zero. As demand for LNG increases and gas prices soar, accurate measurements with low uncertainties are vital for confidence in custody transfer. The case study shows how the liquefier operates, using seven different ISO 17025 accredited reference gas mixtures which are then condensed into liquid into which the optical probe is inserted. The instrument then measures the composition and the results are compared to the known liquid composition.  This calibration of direct measurement LNG analysers avoids the issues of fractionation and enrichment which can occur when using a gas chromatograph and vaporiser for composition measurement. The improved confidence in measurements provided by EffecTech’s liquefier is “essential for LNG to remain a cleaner alternative to other petrochemical products until Europe achieves its future goal of climate neutrality”.
