Analysis of natural gas - Biomethane - Determination of halogenated compounds - Part 1: HCl and HF content by ion chromatography (ISO/FDIS 2611-1:2024)

This document specifies a method for the determination of the concentration of hydrochloric acid (HCl) and hydrofluoric acid (HF) in biomethane, after absorption on an alkali-impregnated quartz fibre filtre or in a sorbent trap, by ion chromatography (IC) with conductimetric detection.
The method is applicable to biomethane for concentration levels for HCl from 0,07 mg/m3 to 35 mg/m3 and for HF from 0,07 mg/m3 to 20 mg/m3.
Unless stated otherwise, all concentrations in this document are given under standard reference conditions (see ISO 13443). Other conditions can be applied.
This method is also applicable to biogas. This method is intended to support conformity assessment of biomethane and biogas according to specifications, such as the EN 16723 series.

Analyse von Erdgas - Biomethan Bestimmung von halogenierten Verbindungen - Teil 1: HCl und HF Anteil durch Ionenchromatographie (ISO/FDIS 2611-1:2024)

Dieses Dokument legt ein Verfahren zur Bestimmung der Konzentration von Salzsäure (HCl) und Flusssäure (HF) in Biomethan nach Absorption auf einem alkali-imprägnierten Quarzfaserfilter oder in einer Sorptionsfalle durch Ionenchromatographie (IC) mit konduktometrischer Detektion fest.
Das Verfahren ist anwendbar auf Biomethan bei Konzentrationen für HCl von 0,07 mg/m3 bis 35 mg/m3 und für HF von 0,07 mg/m3 bis 20 mg/m3.
Sofern nicht anders angegeben, werden alle Konzentrationen in diesem Dokument unter Standardbezugsbedingungen angegeben (siehe ISO 13443). Andere Bedingungen können angewendet werden.
Dieses Verfahren ist auch auf Biogas anwendbar. Dieses Verfahren ist zur Unterstützung der Konformitätsbewertung von Biomethan und Biogas in Übereinstimmung mit Festlegungen (Spezifikationen), wie z. B. der EN 16723 Reihe, bestimmt.

Analyse du gaz naturel - Biométhane - Détermination des composés halogénés - Partie 1: Détermination de la teneur en HCl et HF par chromatographie ionique (ISO/FDIS 2611-1:2024)

Le présent document spécifie une méthode pour la détermination de la concentration d’acide chlorhydrique (HCl) et d’acide fluorhydrique (HF) dans le biométhane, après absorption sur un filtre en fibre de quartz imprégné d’alcali ou dans un piège adsorbant, par chromatographie ionique (CI) avec détection conductimétrique.
Cette méthode est applicable au biométhane pour des niveaux de concentration allant de 0,07 mg/m3 à 35 mg/m3 pour HCl et de 0,07 mg/m3 à 20 mg/m3 pour HF.
Sauf indication contraire, toutes les concentrations figurant dans le présent document sont données dans des conditions de référence normalisées (voir l’ISO 13443). D’autres conditions peuvent être appliquées.
Cette méthode s’applique également au biogaz. Elle est destinée à aider à l’évaluation de la conformité du biométhane et du biogaz conformément aux spécifications, par exemple celles de la série des EN 16723.
