Natural gas - Determination of potential hydrocarbon liquid content - Gravimetric methods (ISO 6570:2001)

This International Standard describes the principles of, and general requirements for, two gravimetric methods for
the determination of the potential hydrocarbon liquid content of natural gas, or similar gas, at a given pressure and
temperature. Two methods are specified in this International Standard to determine the amount of condensate in a
sample gas:
_ Method A: a manual weighing method;
_ Method B: an indirect automatic weighing method based on the indication of the pressure difference caused by
the accumulation of condensate in a vertical tube.
The manual weighing method is a reference method for the indirect automatic method (Method B). The indirect
automatic method (Method B) is suitable for semi-continuous control.
NOTE Unless otherwise specified, gas volumes are in cubic metres at 273,15 K and 101,325 kPa.

Erdgas - Bestimmung des potentiellen Gehaltes an flüssigem Kohlenwasserstoff - Gravimetrische Verfahren (ISO 6570:2001)

Die vorliegende Internationale Norm beschreibt die Prinzipien und Grundanforderungen von zwei gravimetrischen Verfahren zur Bestimmung des potenziellen Gehaltes an flüssigen Kohlenwasserstoffen in Erdgas oder einem ähnlichen Gas bei vorgegebener Temperatur und vorgegebenem Druck. In dieser Internationalen Norm werden zwei Verfahren zum Bestimmen der Kondensatmenge in einem Probegas festgelegt:
-   Verfahren A: ein manuelles Wägeverfahren;
-   Verfahren B: ein indirektes automatisches Wägeverfahren, das auf der Anzeige der durch die Kondensatansammlung in einem senkrechten Rohr hervorgerufenen Druckdifferenz beruht.
Das manuelle Wägeverfahren ist ein Bezugsverfahren für die indirekte automatische Messung (Verfahren A). Das indirekte automatische Verfahren (Verfahren B) ist für die halbkontinuierliche Überwachung geeignet.
ANMERKUNG   Sofern nicht anderweitig festgelegt, bezieht sich das in Kubikmeter angegebene Gasvolumen auf 273,15 K und 101,325 kPa.
