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

Analyse du gaz naturel - Biométhane - Détermination de la teneur en ammoniac par spectroscopie d'absorption laser à diode accordable (ISO/FDIS 2612:2023)

Le présent document décrit plusieurs méthodes d'essai permettant de mesurer la fraction molaire d'ammoniac dans le gaz naturel et le biométhane à l'état de traces (µmol mol−1). Il décrit la manipulation et l'échantillonnage appropriés de mélanges sous pression d'ammoniac dans le méthane appliqués à plusieurs systèmes de mesure de l'ammoniac différents. Les systèmes de mesure comprennent des analyseurs par spectroscopie commerciaux facilement disponibles qui sont spécifiques à l'ammoniac. Ces analyseurs de NH3 sont considérés comme une boîte noire en ce qui concerne leur fonctionnement, qui dépend des instructions du fabricant. Le présent document décrit les stratégies d'étalonnage et de mesurage appropriées pour la quantification de l'ammoniac dans le (bio)méthane aux environs et au-dessus du niveau de 10 mg m−3 (14 µmol mol−1) et s'applique à l'analyse dans des plages de pression absolue de 1 bar à 2 bar, des températures de 0 °C à 40 °C et une humidité relative < 90 %.
Des références sont également faites à des normes supplémentaires qui s'appliquent soit à l'analyse du gaz naturel, soit aux mesures de la qualité de l'air. Dans le présent document, le gaz de la matrice est toujours le méthane ou le biométhane et le mesurande est la fraction molaire de NH3.
NOTE            1 bar = 0,1 Mpa = 105 Pa; 1 Mpa = 1 N/mm2.
