Global warming created by large scale emissions of Greenhouse Gases (GHG) are a worldwide concern. Due to this, the issue of green gas network has required more attention in the last decades. Here, we address the GHG-based problem that arises in a gas network where gas flow is transferred from the Town Board Station (TBS) to consumers by pipeline systems. Given this environment, an optimization...

Transmission and distribution pipelines have a significant role in the oil and gas industries. Pipelines are facing different threat like corrosion, improper design and incorrect operation. Gas vapor released from a pipeline (owned by NIOC) failure spread out and reached to ignition source. Due to gas outdoor spreading, “flash fire” occurred and flame return caused “vapor cloud explosion” of ga...

There are many compressor stations along long-distance natural gas pipelines. Natural gas can be transported using different boot programs and import pressures, combined with temperature control parameters. Moreover, different transport methods have correspondingly different energy consumptions. At present, the operating parameters of many pipelines are determined empirically by dispatchers, re...

A new analytical equation for prediction of temperature profile of a buried gas pipeline is developed. Utility of this equation is illustrated by its application to corresponding states principle. The resulting equation is tested through prediction of the actual Schorre data. It is shown that the new equation can predict temperature profile more accurately than the others without using any char...

Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline anchorage are studied and presented. In this new developed method, geo-textile materials ...

With the rapid development of economy, environmental issues have attracted more and attention from all walks life. As a new type efficient energy, urban gas plays vital role in promoting healthy cities mitigating air pollution. hub gas, stations play distribution, peak regulation pressure regulation, are necessary facilities for safe stable operation pipeline network. increase number stations, ...

Abstract The gas booster station of a steel works has experienced excessive bearing failures since commissioning over two decades ago. This was designed with redundancy, allowing for automatic switch-over between fans. Bearing were observed, on average once every 15.7 days, instances where both fans simultaneous downtime. Booster resulted in regular downtime, preventing Coke Oven Gas (COG) tran...

Two phase gas-liquid flow pattern in a horizontal pipeline is predicted very accurately using a newly-developed analytical relation. The pattern identification is based on one of the most widely used graphs, the Baker diagram, modified in a way that compensates for the unrealistic oversimplifications of recent works. The Kern's method of pressure drop calculation is used to obtain the frict...
