Analysis of natural gas - Biomethane - Determination of ammonia content by Tuneable Diode Laser Absorption Spectroscopy (ISO/FDIS 2612:2023)

This document specifies a Tuneable Diode Laser Absorption Spectroscopy method for the determination of ammonia content of biogas, natural gas or biomethane
This document describes the suitable handling and sampling of pressurised mixtures of ammonia in
methane that are applied to several different ammonia measurement systems. The measurement systems comprise of readily available commercial spectroscopic analysers that are specific to ammonia.
The method is applicable to the determination of ammonia concentrations from 1 mg/m3 (1,3 ppm volume fraction) to 100 mg/m3 (132 ppm volume fraction).
The method has a lower limit of detection of about 0,4 mg/m3 (0,5 ppm volume fraction) NH3 in air with
the tested analyser in Annex B.

Analyse von Erdgas - Biomethan - Bestimmung von Ammoniakanteil durch Absorptionsspektroskopie mittels durchstimmbarer Laserdioden (ISO/FDIS 2612:2023)

Dieses Dokument beschreibt mehrere Prüfverfahren zum Messen des Ammoniakmengenanteils in Erdgas und Biomethan im Spurenbereich (μmol mol-1). Die geeignete Handhabung und Probenahme von druckbeaufschlagten Gemischen von Ammoniak in Methan, die auf mehrere verschiedene Ammoniakmesseinrichtungen angewendet werden, sind beschrieben. Die Messeinrichtungen bestehen aus fertig im Handel erhältlichen spektroskopischen Analysatoren, die spezifisch für Ammoniak sind. Diese NH3-Analysatoren gelten als eine Black Box bezüglich ihres Betriebs, der von den Anweisungen des Herstellers abhängig ist. Das Dokument beschreibt geeignete Kalibrier- und Messstrategien zum Quantifizieren von Ammoniak in (Bio)Methan um und über einem Niveau von 10 mg m−3 (14 μmol mol−1) und gilt für eine Analyse innerhalb von Absolutdruckbereichen von 1 bar bis 2 bar, bei Temperaturen von 0 °C bis 40 °C und bei einer relativen Feuchtigkeit von <90 %.
Es sind ebenfalls Verweisungen auf zusätzliche Normen enthalten, die auf die Erdgasanalyse oder auf Luftqualitätsmessungen angewendet werden. In diesem Dokument ist das Matrixgas immer Methan oder Biomethan und die Messgröße ist der Stoffmengenanteil NH3.
ANMERKUNG 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2
