Natural gas — Determination of water by the Karl Fischer method — Part 2: Volumetric procedure
This document specifies a volumetric procedure for the determination of water content in natural gas. Volumes are expressed in cubic metres at a temperature of 273,15 K (0 °C) and a pressure of 101,325 kPa (1 atm). It applies to water concentrations between 5 mg/m3 and 5 000 mg/m3.
Analysis of natural gas — Biomethane — Determination of amines content
This document specifies the determination of the concentration of alkanolamines in biomethane. The measurement method involves thermal desorption gas chromatography with flame ionization and/or mass spectrometry detectors (TD-GC-MS/FID). The described method is specifically developed for the analysis of five amine compounds, namely:
— monoethanolamine (MEA);
— diglycolamine (DGA);
— …
