Natural gas - Gas sampling (ISO 10715:2022)
This document gives means for ensuring that samples of natural gas and natural gas substitutes that are conveyed into transmission and distribution grids are representative of the mass to which they are allocated.
NOTE To ensure that a particular gas is taken into account in the standard, please see Annex A.
This document is applicable for sampling at sites and locations where interchangeability criteria, energy content and network entry conditions are measured and monitored and is particularly relevant at cross border and fiscal measurement stations. It serves as an important source for control applications in natural gas processing and the measurement of trace components.
This document is applicable to natural dry gas (single phase - typically gas transiting through natural gas pipelines) sampling only. On occasion a natural gas flow can have entrained liquid hydrocarbons. Attempting to sample a wet natural gas flow introduces the possibility of extra unspecified uncertainties in the resulting flow composition analysis. Sampling a wet gas (two or three phases) flow is outside the scope of this document.
This document does not apply to the safety issues associated with gas sampling.
Erdgas - Probenahme (ISO 10715:2022)
Dieses Dokument enthält Mittel, mit denen sichergestellt wird, dass Proben von Erdgas und Erdgasaustauschgas, das in Fernleitungs- und Verteilungsnetze geleitet wird, repräsentativ für den Gasstrom sind, dem sie zugeordnet sind.
ANMERKUNG Um sicherzustellen, dass ein bestimmtes Gas in der Norm Berücksichtigung findet, siehe Anhang A.
Dieses Dokument ist für die Probenahme an Standorten und Stellen anwendbar, an denen Austauschbarkeitskriterien, Energiegehalt und Netzeinspeisebedingungen gemessen und überwacht werden, und ist insbesondere an grenzüberschreitenden und abrechnungsrelevanten Messstellen maßgebend. Es dient als wichtige Quelle für Kontrollanwendungen in der Erdgasverarbeitung und für die Messung von Spurenbestandteilen.
Dieses Dokument ist nur für die Probenahme von trockenem Erdgas (einphasig — üblicherweise Gas, das durch Erdgasleitungen fließt) anwendbar. Gelegentlich kann ein Erdgasfluss mitgenommene flüssige Kohlenwasserstoffe enthalten. Der Versuch, einen feuchten Erdgasfluss zu beproben, führt möglicherweise zu zusätzlichen, nicht spezifizierten Unsicherheiten bei der Analyse der resultierenden Gasflusszusammensetzung. Die Probenahme aus einem feuchten Gasfluss (zwei- oder dreiphasig) liegt nicht im Anwendungsbereich dieses Dokuments.
Dieses Dokument ist nicht für die Sicherheitsfragen in Zusammenhang mit der Gasprobenahme anwendbar.
WARNUNG — Allgemeine Aspekte der Erdgasbeschaffenheit sind in ISO 13686 [1] ausführlich beschrieben. Möglicherweise deckt die Norm nicht alle Spurenbestandteile ab, deren Überwachung aus verschiedenen Gründen zunehmend notwendig ist.
Gaz naturel - Échantillonnage de gaz (ISO 10715:2022)
Zemeljski plin - Vzorčenje (ISO 10715:2022)
Ta dokument določa sredstva za zagotavljanje, da so vzorci zemeljskega plina in nadomestkov zemeljskega plina, ki se prenašajo v prenosna in distribucijska omrežja, reprezentativni za maso, ki so ji dodeljeni. OPOMBA: Ali je določen plin upoštevan v standardu, je mogoče preveriti v dodatku A. Ta dokument se uporablja za vzorčenje na mestih in lokacijah, kjer se merijo in spremljajo merila medsebojne zamenljivosti, vsebnost energije ter vstopni pogoji za omrežje. Še posebej je pomemben pri čezmejnih postajah in sistemih fiskalnega merjenja. Je pomemben vir za izvajanje nadzora pri predelavi zemeljskega plina in merjenju komponent v sledovih. Dokument se uporablja samo za vzorčenje suhega zemeljskega plina (enofaznega – običajno plina, ki teče po plinovodih za zemeljski plin). Zgodi se, da tok zemeljskega plina vsebuje tekoče ogljikovodike. Pri poskusu vzorčenja toka mokrega zemeljskega plina in analizi njegove sestave lahko pride do dodatnih nedefiniranih negotovosti. Vzorčenje toka mokrega plina (dvo- ali trifazni) ne spada na področje uporabe tega dokumenta. Dokument se ne navezuje na varnostna vprašanja, povezana z vzorčenjem plina.
