Paper Number: PSIG-2110
... of the exposed alloys must be limited to consumption, and as a result a different fuel consumption. Since below 827 MPa (120 ksi). Hydrogen molecules are small the transported gas is also used as fuel supply for the gas compared to most hydrocarbon gases, which makes case-end turbines that drive the pipeline...

... is to control the units such, that certain operational parameters, for example fuel consumption, pipeline capacity or maintenance requirements, are optimized. The discussion includes the use and sizing of multiple units, the arrangement of units, the arrangement as push or pull compression, as well as examples...

... that the transient state of the network is described by the system of partial differential equations of hyperbolic type expressing mass, momentum and energy conservation in pipes and flow conservation in nodes. The optimization criterion is to minimize the fuel consumption of the compressor stations. Each compressor...

... AND BACKGROUND Natural gas is usually transported by pipeline networks which serve as the most cost effective transportation means. Transmission systems usually have a linear topology corresponding to a linear arrangement of compressor stations. The fuel consumption of compressors is responsible for a large...

.... The potential to lower CAPEX (due to lower compression power requirement) and OPEX (due to lower fuel consumption) are counteracted by the extra cost of the internal coating. In this paper, a large diameter pipeline case study is used to evaluate the alternatives of (a) coating versus (b) not coating...

... various pipeline conditions. The two questions that will be answered are: 1. What is the flow and pressure ratio capability? 2. What is the fuel consumption? The methodology in this paper has been successfully used by Gordon Muster of El Paso Corporation to model several two-shaft gas turbine engines...
