Natural Gas Pipelines

Numerical simulation of transient natural gas flow in pipelines using high order DG-ADER scheme

To increase the numerical accuracy in solving engineering problems, either conventional methods on a fine grid or methods with a high order of accuracy on a coarse grid can be used. In the present research, the second approach is utilized and the arbitrary high order Discontinues Galerkin Arbitrary DERivative (DG-ADER) method is applied to analyze the transient isothermal flow of natural gas th...

Using Operating Data at Natural Gas Pipelines

INTRODUCTION Interstate natural gas pipelines are operated using sophisticated supervisory control and data acquisition (SCADA) systems. These systems are used to monitor, control and analyze operations. Software which runs in conjunction with the basic SCADA system expands the usefulness of SCADA data to enhance reliability and efficiency of operations, improve customer service, and minimize u...

Natural gas and CO2 price variation: impact on the relative cost-efficiency of LNG and pipelines

THIS ARTICLE DEVELOPS A FORMAL MODEL FOR COMPARING THE COST STRUCTURE OF THE TWO MAIN TRANSPORT OPTIONS FOR NATURAL GAS: liquefied natural gas (LNG) and pipelines. In particular, it evaluates how variations in the prices of natural gas and greenhouse gas emissions affect the relative cost-efficiency of these two options. Natural gas is often promoted as the most environmentally friendly of all ...

Technology Status Report on Natural Gas Leak Detection in Pipelines

However, any opinions, findings, conclusions, or recommendations expressed herein are those of the author and do not necessarily reflect the views of the DOE". Natural gas consumption in the US is expected to increase 50% within the next 20 years (Anderson and Driscoll, 2000). At the same time, the gas delivery infrastructure is rapidly aging. The Department of Energy has stated that ensuring n...
