Search for: [Description = Coalbed methane is extracted from the adsorbed state in coal seams with lower pressure \& production rate. In previous studies, researchers only focused on the methods that were developed for making a relationship between the underground production rate \& surface flow rate without any type of optimization procedure. In this study, the main purpose is to do a review on finding out of surface layout plan to optimize the maximum gas flow rate by developing an improved pipeline network. The more the optimization of the layout plan for designing pipeline network, the lower the amount of investment need to provide. Here, a mathematical model is proposed for the gas transportation based on the hydraulic \& thermodynamic calculations of the pipeline network. Not only that, but also the filtration mechanism of depressurization \& desorption for the gas flow through pipe section are evaluated here. After that, the pressure drop \& pipeline efficiency are explored to find out the best design of pipeline network from the observed results. Finally, based on this study, many uncertainties can be reduced associated with the installation of pipeline network for gas transportation.]
