Recent environmental concerns have led to calls for reduced hydrocarbon emissions to the atmosphere from a variety of sources. One source of emissions being examined in this regard is natural gas spot sampling methods that vent pipeline gases to the…
Probes for natural gas sample collection and analysis must extend far enough into the pipeline to avoid contaminants at the pipe wall, but must not be so long that there is a risk of flow induced resonant vibration and failure. PRCI has sponsored a…
This report summarizes a follow-on task to the project in which SmallTech Consulting was asked by PRCI to undertake an evaluation of MEMS1 Technology for Natural Gas/Liquid Quality Measurement. SmallTech examined the feasibility of using MEMS-based…
Phase II was originally planned as a series of field tests to confirm the results of the sampling methods performance tests conducted during Phase I. However, the API Chapter 14.1 Gas Sampling Research Working Group chose to have the tests conducted…
In 1998, a multi-year project to develop a working prototype instrument module for natural gas energy measurement was initiated. The module will be used to retrofit a natural gas custody transfer flow meter for energy measurement, at a cost an order…
Research has been conducted to assess the usefulness of various sampling and delivery methods in transporting a representative sample of a natural gas stream for analysis of moisture content. Three sampling configurations commonly used by the natural…
Probes for natural gas sample collection and analysis must extend far enough into the pipeline to avoid contaminants at the pipe wall, but must not be so long that there is a risk of flow-induced resonant vibration and failure. PRCI has sponsored a…
In natural gas production and processing applications, methanol is commonly injected into natural gas streams containing water to prevent the formation of hydrates in gas lines and subsequent equipment damage. However, gas chromatographs (GCs) at…
Deepwater natural gas production is a non-traditional operation that is very different than conventional shelf or onshore production, due to the extremely high pressures (2,000 psia, 13.8 MPa abs) and rich gases (1,300 Btu/scf, 48.4 MJ/Nm3) involved.…
This project evaluated selected single-phase gas sampling methods as candidates for use in sampling hydrocarbon-wet gas streams and obtaining representative samples of only the gas phase, rather than samples of both the gas and liquid. Two spot…
