Abstract: Since a gas sampling system can be referred to as a cash register it is very important that the correct sampling method be selected and the appropriate industry standard be followed. Methods reviewed by this paper will include spot sampling, composite sampling, and on-line chromatography. In addition, Gas Processors Association (GPA) 2166-86 and American Petroleum Institute (API) 14.1 will be described. Natural gas is sampled to determine quality for custody transfer applications, balance a plant process, or gathering system. In the late 1970s most natural gas custody transfer contracts used gas volume (MCF) for the units of measure. In 1978 Congress passed the Natural Gas Policy Act in an attempt to deregulate the natural gas industry. This act dictated that natural gas should be purchased or sold based on energy content. Today natural gas is purchased based on the amount of energy delivered. The quantity of energy delivered is calculated by multiplying the gas volume per unit time by the energy value (BTU) per unit volume. A gas chromatograph is typically used to identify individual components of the sample and their quantity, thus determining quality of the sample taken. Correctly obtaining, transporting and analyzing the sample is crucial to the accuracy required for custody transfer of this product.
