A METHOD FOR DETERMINATION OF A QUALITY PARAMETER OF A HYDROCARBON GAS MIXTURE

摘要

The invention relates to a method for determination of a quality parameter of a hydrocarbon gas mixture, such as LNG, CNG or SNG, the method comprising subjecting at least a part of the hydrocarbon gas mixture to an NMR reading comprising generating a H data comprising a H NMR spectra and correlating the H NMR data to calibration data, wherein the calibration data relates the H NMR data to at least one quality parameter of the hydrocarbon gas. The invention also relates to a system suitable for determination of a quality parameter of a hydrocarbon gas mixture according to the method.
