Modelling of a Modular Gas Gathering and Transportation System for an Urban Centre
Authors: Akhile E, Bello K
In this work, natural gas gathering and transmission system has been designed for Benin City, Edo State, Nigeria. This was carried out using industry simulation software, PIPESIM in order to minimize gas flaring and take advantage of clean energy source. A number of designs were considered particularly for different pipe sizes and network patterns. They include series piping connection, two parallel piping connection and three parallel piping connection. In the light of above, given the different design patterns, two-parallel-piping connection was recommended as the optimal design for delivering the processed natural gas streams to various locations in Benin City from gas hitherto flared in a field near Benin. The two-parallel-piping connection was found to be the design pattern that would optimally deliver natural gas to the various locations and hence recommended for any real-life situation. This is because though with a two parallel-pipes connection system, there will be an increase in construction cost as well as operating cost, it still delivers the highest flow rate compared to the two other design patterns. Compared to the series piping system, the two parallel pipes connection system delivers a natural gas flow rate of 1.146 MMSCFD higher than that of the series connection. Also, in cases when the pipelines have challenges such as corrosion, burst, delivery of natural gas will be totally impeded for a series connection until the pipe is replaced but for a two parallel-pipes connection delivery may still continue if just one pipe is affected.
