Integrated simulation study of gas pipeline network in Bangladesh

Abstract

Bangladesh is considered a natural gas rich country. Twenty six gas fields have been discovered in Bangladesh out of which 19 (nineteen) fields are producing gas at present through 92 producing wells. The natural gas transmission pipeline infrastructure in Bangladesh that delivers about 2500 MMSCF of natural gas per day, and is made up of over 2406.82 km of pipe. At present a parallel pipeline (36" × 137 km) is being commissioned for transmitting additional gas from Bibiyana to Dhanua. Another 177 km new pipeline is going to be added to the existing network after completing the river crossing operation in Padma River, to include Kushtia, Jessore and Khulna regions. To meet the future demand, the existing pipelines are not enough to transmit large volume of gas. Before taking up construction work of new transmission lines, an extensive study of a pipeline network simulation model for this country is required. A mathematical model to simulate pipeline system operation is constructed covering this entire existing system. The model is first validated by matching with the existing network using known data. Sensitivity studies are performed to investigate the effect of supply-demand fluctuations. In this project work commercial software “PIPESIM” is used for gas pipeline network analysis and simulation.
