... ABSTRACT Many gas compressor stations use multiple gas turbine driven centrifugal compressors. In many instances, the units are not identical. The challenge is to control the units such, that certain operational parameters, for example fuel consumption, pipeline capacity or maintenance...

... conservation in pipes and flow conservation in nodes. The optimization criterion is to minimize the fuel consumption of the compressor stations. Each compressor station can be equipped with gas turbine driven centrifugal compressors and/or motor-compressors, and has a local optimization algorithm for given...

... is solved to evaluate the type and the number of simultaneously operating compressors, while determining such a distribution of the capacity that the total unit fuel consumption in each time interval is minimized subject to the constraints imposed. The paper presents an algorithm of automatic search...

.... 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...

... questions that will be answered are: What is the flow and pressure ratio capability? 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. INTRODUCTION What a gas turbine...

... has been developed to demonstrate the value of the results and prove the feasibility of this approach. Details of the compressor model program are presented in this paper.

... ABSTRACT Optimization of a large gas pipeline network results in reduced hydraulic analysis time, reduced fuel consumption, and generally improved pipeline operation. This paper evaluates the practical and technical application of a Genetic Algorithm-based optimization tool, which accurately...

... variables are chosen to be the operating speeds of the units in the compressor stations, while the objective function is taken to be the average fuel consumption rate over the interval of interest, summed over all units. The constraint functions gj( b ) are formulated suitably to ensure that operational...
