The committee on gas fluids measurement conducted a thorough review and revision of Part 2 of API Chapter 14.3,AGA Report #3. The report incorporated the installation requirements from improvements in technology gathered from research and the field experience gained.
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.
Evaluated the ability of four designs of ultrasonic flowmeters to detect leaks in pipelines. Calibrated the meters at the Exxon clean crude facility at Baytown, Louisiana and then at the raw crude terminal at Grand Isle, Louisiana.
