Perform transient analysis of a gas pipeline

M. A. Arce, ICA Fluor, Mexico City, Mexico Natural gas pipelines are increasingly important pieces of infrastructure to help maintain the high momentum of gas production, especially shale gas. Many countries have developed wide networks enabling gas transportation to highly populated areas, where the gas is used for power generation and heating. The transport of gas requires a different analysis than does the transport of liquids. Gas is more heavily impacted than liquids by changes in pressure and temperature, and this difference affects the flow behavior of gas vs. liquids under the same conditions. For gas lines (both process lines and in-plant lines), there is a set of considerations
