Natural gas — Determination of potential hydrocarbon liquid content — Gravimetric methods

Standard Details

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.
