Analysis of natural gas - Biomethane - Determination of halogenated compounds - Part 1: HCl and HF content by ion chromatography (ISO/DIS 2611-1:2023)

This document specifies a method for the determination of the concentration hydrochloric acid and hydrofluoric acid in biomethane, after absorption on an alkali-impregnated quartz fiber filter or in a sorbent trap, by ion chromatography (IC) with conductimetric detection.
The method is applicable to biomethane in levels:
- for HCl: 0,07 mg/m3 to 34,3 mg/m3;
- for HF: 0,07 mg/m3 to 17,5 mg/m3.

Analyse von Erdgas - Biomethan Bestimmung von halogenisierten Verbindungen - Teil 1: HCl und HF Anteil durch Ionenchromatographie (ISO/DIS 2611-1:2023)

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 dieser Norm unter Standardbezugsbedingungen angegeben (siehe ISO 13443 [3]). Andere Bedingungen dürfen 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. EN 16723 [1][2], bestimmt.
