ISO/TR 12148:2009
Natural gas -- Calibration of chilled mirror type instruments for hydrocarbon dewpoint (liquid formation)
Product Details
If the gas composition is constant, the manual weighing method (method A) described in ISO 6570:2001 is also applicable.
The application of this calibration procedure in the upstream area is not excluded a priori, however, currently there is no experience using this procedure in an upstream environment.
The usability of data on the potential hydrocarbon liquid content of natural gas for verification, adjustment or calibration of hydrocarbon-dew-point chilled-mirror instruments is based on the condensation behaviour of natural gases. ISO/TR 12148:2009 provides information on the condensation behaviour of natural gases and the various measuring techniques to determine properties, like hydrocarbon dew point and potential hydrocarbon liquid content, related to the condensation behaviour of natural gases.
