Analysis of natural gas - Biomethane - Determination of amines content (ISO/TS 2610:2022)
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); — diethanolamine (DEA); — N-methyldiethanolamine (MDEA); — piperazine (PZ). Information about the compounds is given in Annex A.

Gas Infrastructure - CEN/TC 234 Pressure Definitions - Guideline Document
This Technical Report gives explanation on the pressure definitions and pressure units used by the gas network operators with regard to the standards of CEN/TC 234 “Gas infrastructure” listed in Clause 2. The European Standards of CEN/TC 234 comprise the functional requirements in the field of gas infrastructure from the input of gas into the on-shore transmission network up to the inlet connection of gas appliances, including transmission, distribution, storage, compression, pressure regulation and metering, installation, injection of (renewable) gases such as biomethane, hydrogen, gas quality issues and others.

Gas infrastructure - Quality of gas - Hydrogen used in rededicated gas systems
This document defines the quality of gaseous hydrogen, i.e. its parameters and limiting values, to be transmitted, injected into and extracted from storages, distributed and utilized in fully and/or partially rededicated gas infrastructure and connected applications in a safe way. This document gives evidence to the end-user which minimum exit hydrogen quality can be expected and ensured from natural gas infrastructure as minimum requirement and without further purification. NOTE 1 The rededicated gas infrastructure can include new parts of this infrastructure constructed/added after the conversion of the natural gas grid. NOTE 2 It is expected that over time the hydrogen delivered through such pipework will improve in quality, e.g. due to the increase in share of high purity hydrogen produced by electrolysis This will be taken into account in further development of this document.
