D.o.t. Requirements For The Transportation Of Sample Cylinders

Author: David J. FishDownload File

The United States Department of Transportation (D.O.T.) is a department of the U.S. Federal Government which oversees all issues regarding transportation within the United States of America and U.S. Territories. Its influence around the world is great and widely respected, but its jurisdiction and power of enforcement is limited to the USA and its territories. […]

Determination Of Hydrogen Sulfide And Total Sulfur In Natural Gas

Author: Marshall T. SchreveDownload File

Hydrogen Sulfide (H2S) is a gas composed of one Sulfur Atom and two Hydrogen Atoms. H2S is formed by the decomposition of organic matter and is therefore, found naturally in crude oil and natural gas deposits. H2S is a highly toxic, transparent, colorless and corrosive gas. Due to the toxic and caustic properties of this […]

Devices For Field Determination Of H2o In Natural Gas

Author: Sam MillerDownload File

H2O vapor is an undesirable component of natural gas. It takes up space in the pipeline and provides no fuel value. In higher concentrations it can condense into liquid water in the pipeline and cause corrosion, especially in the presence of carbon dioxide or H2S. Liquid water can also cause damage to turbines. Because of […]

Dew Point Wet Gas And Its Effect On Natural Gas Sampling Systems

Author: Philip A LawrenceDownload File

Wet gas measurement is becoming widely used in the modern oil and gas market place. The effect of entrained liquid in gas and its impact on measurement systems is being researched world-wide by various laboratories and JIP working groups. The impact can be very significant financially. Hydrocarbon Dew Point can also effect the financial operation […]

Measuring Hydrocarbon Dew Point

Author: Sohrab ZarrabianDownload File

Hydrocarbon Dew Point (HDP) remains one of the key quality parameters of natural gas streams. Its determination is needed for operational and safety considerations, as well as to satisfy tariffs and regulations in US and overseas pipeline operations. The recent development of shale gas in US has added to the need for accurate and consistent […]

Operation Of On-line Gas Chromatographs

Author: Bill FrazierDownload File

Gas Chromatographs serve as a basis for measurement of individual Natural Gas Components to determine the BTU or Energy Value of the Natural Gas. The use of “On-Line” Gas Chromatographs enables the end user to know 100% of the time the energy value of the gas flowing through their system. It is much like using […]

Overview Of Equations Of State (eos)

Author: Adam G. Hawley & Darin L. GeorgeDownload File

Determination of fluid properties and phase conditions of hydrocarbon mixtures is critical for accurate hydrocarbon measurement, representative sampling, and overall pipeline operation. Fluid properties such as compressibility and density are critical for flow measurement, and determination of the hydrocarbon due point is important to verify that heavier hydrocarbons will not condense out of a gas […]

Sampling Challenges Associated With Unconventional Gas Sources

Author: Mark FirminDownload File

Advances in exploration, drilling and production technologies make it feasible to extract natural gas from sources that in the past have been regarded as unconventional and so, such sources are becoming a larger percentage of the gas supply. The feasibility of producing gas from a source is the primary factor in determining whether that source […]

Techniques For Composite Gas Sampling

Author: David J. FishDownload File

The need to be able to take a representative sample of a hydrocarbon product is necessary to ensure proper accounting for transactions and efficient product processing. The various sampling methods that are available and the options and limitations of these methods are investigated; the most appropriate equipment to use; the reasons for its use and […]

Techniques For Spot Sampling Gas

Author: Matthew S. ParrottDownload File

While inaccuracies in measurement can be costly and common, they are also avoidable in most cases. Technicians willing to study the experiences and best practices of industry leaders can make a world of difference by applying what they’ve learned and sharing the knowledge shared in this paper with others. This paper aims to describe spot […]
