This was a Joint Industry Project (JIP). The project was to verify methods to accurately sample gases. The effects of several variables on the repeatability of sampling were studied. Spot, composite, and continuous sampling was evaluated under various field conditions. Variables studied include: vertical and horizontal runs, location of sampling probes relative to orifice meter, effects of gas composition on sampling integrity, use of GPA separators, flowing temperature in the vicinity of the dew point, re-vaporization of chilled samples swirling flows. The sampling test that was performed helped identify difficulties with the procedure in the proposed test protocol, and to determine the practicalities of the procedure and its ease of implementation in field settings. Primary goal was to evaluate the test protocol itself, and a secondary goal was to determine the ability of several new sampling methods to provide representative gas samples.
The project is completed and accepted in July 2004.
