Natural gas - Calculation of compression factor - Part 2: Calculation using molar-composition analysis (ISO 12213-2:2006)

ISO 12213 specifies methods for the calculation of compression factors of natural gases, natural gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as a gas.
It is divided into three parts: this part, ISO 12213-2:2006, specifies a method for the calculation of compression factors when the detailed composition of the gas by mole fractions is known, together with the relevant pressures and temperatures.
The method is applicable to pipeline quality gases within the ranges of pressure p and temperature T at which transmission and distribution operations normally take place, with an uncertainty of about +/- 0,1 %. It can be applied, with greater uncertainty, to wider ranges of gas composition, pressure and temperature.

Erdgas - Berechnung von Realgasfaktoren - Teil 2: Berechnungen basierend auf einer molaren Gasanalyse als Eingangsgröße (ISO 12213-2:2006)

Gemische Verfahren zur Berechnung der Realgasfaktoren unter Bedingungen fest, unter denen das Gemisch
nur als Gas existieren kann.
In diesem Teil von ISO 12213 wird ein Verfahren zur Berechnung der Realgasfaktoren für Gase festgelegt,
deren genaue stoffmengenmäßige Zusammensetzung ebenso wie die zutreffenden Drücke und
Temperaturen bekannt sind.
Das Verfahren ist mit einer Unsicherheit von etwa ± 0,1 % auf aufbereitete Erdgase innerhalb der Bereiche für
den Druck p und die Temperatur T anwendbar, bei denen Transport- und Verteilungsvorgänge üblicherweise
ablaufen. Es kann — mit höherer Unsicherheit — auch auf erweiterte Bereiche der Gaszusammensetzung,
des Drucks und der Temperatur angewendet werden (siehe Anhang E).
Weitere Angaben zum Geltungs- und Anwendungsbereich des Verfahrens sind in ISO 12213-1 enthalten.

Gaz naturel - Calcul du facteur de compression - Partie 2: Calcul à partir de l'analyse de la composition molaire (ISO 12213-2:2006)

L'ISO 12213 spécifie des méthodes pour le calcul des facteurs de compression des gaz naturels, des gaz naturels contenant un adjuvant synthétique et de mélanges similaires dans des conditions telles que le mélange ne peut exister que sous forme gazeuse.
Elle est divisée en trois parties: la présente partie, l'ISO 12213-2:2006, spécifie une méthode pour le calcul des facteurs de compression lorsque la composition détaillée du gaz par fractions molaires est connue, ainsi que les pressions et les températures correspondantes.
La méthode est applicable au gaz de qualité réseau dans les plages de pression, p, et de température, T, dans lesquelles s'effectuent normalement les opérations de transport et de distribution, avec une incertitude de l'ordre de +/- 0,1 %. Elle peut s'appliquer, avec une incertitude plus élevée, à des plages plus étendues de composition des gaz, de pression et de température.

3Z is calculated as follows: first the values of B and nC∗(n = 13 to 58) are calculated, using relationships given in Annex B. Equations (1) and (3) are then solved simultaneously for ρm and Z by a suitable numerical method (see Figure B.1). 4.3 Input variables The input variables required for use with the AGA8-92DC equation are the absolute pressure, absolute temperature and molar composition.
