Contains analyses and related source data for 451 natural gas samples from 15 States. Of the total samples, 381 were collected during the calendar years 2002 through 2004. The remaining 70 were collected earlier, but releases granting permission to…
Twenty manufacturers participated to the Gas Quality Benchmark. Answers were given for 15 out of 16 compounds or categories of compounds. Only for "biological agents", no answer was collected. The answers are technical responses from the market to…
This report describes the tests results carried out on five natural gas gross calorific value analyzers depending on the calibration model. Three analyzers were conventional gas chromatographs. Two analyzers were new generation gas chromatographs.…

Nine operators participated to the gas Quality Benchmark. Fourteen compounds (or compound categories) were listed. The majority of gas operators are satisfied with the way analyses are currently carried out. . A significant need was however…
Gas quality specifications are set for commercial considerations and are influenced by several engineering factors including preventing corrosion, preventing blockages from freezing and hydrates, and the heating value of the gas. The Office of…
The natural gas industry currently relies on gas chromatography to evaluate the composition of natural gas including alkanes, carbon dioxide, nitrogen, and oxygen. The higher and lower heating values, Wobbe Index, Hydrocarbon Dewpoint, Methane…
Many pipelines utilize system chromatographs at delivery locations. The energy content of the gas delivered can have a significant time skew from the chromatograph. Therefore, the energy content of the gas at a delivery point may differ significantly…
Three hydrogen sulfide (H2S) monitors calibrated to detect concentrations between the ranges of zero to fifty parts per million (ppm) were acquired by the PRCI project advisory team and sent to GTI for evaluation. The three tested monitors were from…
