Abstract:
The gas transmission pipelines in Bangladesh were initially planned and constructed
targeting particular bulk consumers or potential load centers. In the early stage of the
development of the gas sector, the grid system was possibly not visualized. But over the
years the gas transmission system has expanded considerably and has become
complicated.
The objective of the study is to perform gas transmission network analysis of Bangladesh.
The study has been undertaken to simulate the present network system, identify its
limitations and suggest remedial measures. This study would be useful to understand the
performance of the present gas transmission system of Bangladesh. This study would also
analyze the existing pipeline capacity and examine the level of capacity utilization.
The work was completed with the help of a commercial software, PIPES 1M-Net. After
pressure matching at different load centers, manifold stations and branches, different
scenarios were studied for future performance prediction. Finally, the scenarios were
discussed and highlighted different important points through conclusion and
recommendation. The simulated results will be helpful to identify the bottlenecks and to
plan for future expansion of gas transmission system.
There are twenty-two gas fields in Bangladesh. But twelve producing gas fields can
produce 1300 MMSCFD of gas from 53 gas wells. The study shows that Ashugonj
metering station is the focal points of the National Gas Grid. Gas from the North-Eastern
Gas Fields are being transported through the North-South pipeline to Ashuganj Manifold
Station of GTCL from where it is further transmitted to Titas franchise area (TFA) and
Bakhrabad franchise area (BFA) through Brahmaputra Basin pipe line and Ashuganj-
Bakhrabad Transmission pipe lines. From Bakhrabad Gas Field, Bakhrabad-Chittagong
Pipeline transports part of the required gas for Chittagong. The remaining gases for
Chittagong is supplied from Salda, Meghna and Sangu gas fields.
