Natural gas has been recognized as a promising energy supply for modern society due to its relatively less air pollution in consumption, while pipeline transportation is preferred especially long-distance transmissions. A simplified control scenario proposed this paper deeply accelerate the management and decision process dispatch, which direct relevance between compressor operations inlet flux...

Methane emissions from natural gas delivery and end use must be quantified to evaluate the environmental impacts of natural gas and to develop and assess the efficacy of emission reduction strategies. We report natural gas emission rates for 1 y in the urban region of Boston, using a comprehensive atmospheric measurement and modeling framework. Continuous methane observations from four stations...

In order to solve the selection of the optimal wavelet basis for the gas pipeline leak monitoring, the feature of wavelet basis especially for gas pipeline leak monitoring and positioning has been summarized based on the analyze of wavelet basis parameters characteristic and gas pipeline leak negative pressure wave signal feature. A parameter which named reconstruction and mutation joint factor...

In this study, operation of compressor station has been investigated by exergy approach. Exergy analysis is a thermodynamic method which shows the irreversibility of a system quantitatively. Gas compressors are used to compensate the pressure drop along the gas pipeline significantly. The compression process causes temperature rise of gas; in this regard gas cooler is applied to reduce the temp...

With the growth of electricity generation from gas energy gas pipeline reliability can substantially impact the electric generation. A physical disruption to pipeline or to a compressor station can interrupt the flow of gas or reduce the pressure and lead to loss of multiple gas-fired electric generators, which could dramatically reduce the supplied power and threaten the power system security....

• The transportation and consumption of oil and natural gas in the continental United States may be directly affected by new regulations and legislation, including (1) the Clean Power Plan proposed by the U.S. Environmental Protection Agency (EPA), (2) railcar rules proposed by the U.S. Department of Transportation (DOT), and (3) proposed laws related to the controversial Keystone XL Pipeline e...

Thanks to recent progress in satellite-based remote sensing technologies and object oriented image analysis, as well as to the availability of new very high-resolution sensors, it is now possible to design gas pipeline monitoring systems, as has been demonstrated by the co-funded European “PRESENSE Pipeline REmote SENsing for Safety and the Environment” project. In parallel, the European Space ...
