Transients in Gas-Condensate Natural Gas Pipelines

Journal of Energy Resources Technology, 1998
Liquid condensation in natural gas transmission pipelines commonly occurs due to the thermodynamic and hydrodynamic imperatives. Condensation subjects the gas pipeline to two-phase transport. Neither the point along the pipeline at which the condensate is formed nor the quantity formed is known a priori.

Natural Gas Pipeline Leaks Across Washington, DC

Environmental Science & Technology, 2014
Pipeline safety in the United States has increased in recent decades, but incidents involving natural gas pipelines still cause an average of 17 fatalities and $133 M in property damage annually. Natural gas leaks are also the largest anthropogenic source of the greenhouse gas methane (CH4) in the U.S.

Flow Equations for Natural Gas Pipelines

Transactions of the American Society of Civil Engineers, 1958
In use of various equations in pipe line design, practice is to apply Pipeline Efficiency factor; three equations most widely used for design are given; use of equations in operation study and capacity testing; difference between flow equation; determining behavior of resistance coefficient.

Pipeline Promises [natural gas technology]

Engineering & Technology, 2014
Gas was considered a strictly limited resource until the USA's experience with shale gas. Hydraulic fracturing or fracking - has brought huge reserves of gas to the nation at an affordable cost and the impact has been profound.

Powering of Natural Gas Pipelines

Journal of Engineering for Power, 1972
An expression is developed for natural gas pipeline flow in terms of station power rather than the usual differences in the squares of the pressures, thus making it possible to directly evaluate the relative worth of power addition to existing lines or evaluate pipe versus power for new lines. Specific power requirements in terms of power per unit flow

Natural gas pipeline accident consequence analysis

Process Safety Progress, 2004
Abstract Industrial licensing activities require safety and environmental studies to enhance safety and environmental protection especially as applied to pipelines. After World War II, industrial activities increased and accident risk analyses are now routinely made to reduce hazards.

Flow of Natural Gas in Pipelines

Transactions of the American Society of Civil Engineers, 1957
Flow formulas in use in design of natural gas transmission pipelines, and performance ratings of these lines; formulas are derived from general energy equation, basic difference being found in methods of considering friction coefficient, and in adjustment for deviation of gases for supercompressibility; each formula, after applying all adjustments ...

Safe Purging of Natural Gas Pipelines

SPE Production Engineering, 1988
Summary When a newly constructed natural gas pipeline is put into service, it can be safely purged of air by injection of a slug of inert gas, such as N2. The method of sizing the required slug is based on a model of dispersion in turbulent flow in conjunction with flammability limits.

Monitoring of Natural Gas Pipeline Leaks

2010 8th International Pipeline Conference, Volume 3, 2010
Pipe is a very important tool for long-distance transportation of nature gas. In the long-term running, there will be inevitably an appearance of a rupture, leak or damage usually caused by manmade event or by nature disaster. Leaks may generate dangerous clouds of gas escaping from the high-pressure pipe and produce serious incidences involving fire ...

Natural Gas Pipelines and Monopoly

1989
The natural gas pipeline industry is no longer a protected natural monopoly. Regulation policy favors increased competition and open access to the transportation network. Entry barriers to the commodity are not sustainable with the emergence of an active spot market. Bypass of the local distribution facilities by heavy users is occurring.
