Multiobjective optimization of a multinodal gas pipeline

Abstract

Natural Gas is a sweeter source of energy present in abundant amounts (187.3 TCM) (Dudley, 2013). For transporting Natural Gas to very long distances, pipelines have been considered as the most economical, effective and safe mode as compared to other transportation methods. As the gas moves in pipeline network some of its pressure energy is lost due to friction, elevation and heat transfer between the gas and its surrounding. This necessitates boosting the pressure of gas that is achieved through compression of gas using compressors. The energy required to run compressors is obtained by the combustion of a part of natural gas being transported. The amount of natural gas consumed as fuel is immense and even a very small saving in fuel consumption can save considerable currency.
