Abstract:
The study is to develop an optimized pipeline system design for transportation of gas in Niger Delta was investigated. Hydrocarbon Gas is moved from central storage facilities over long-distance trunk lines to refineries or other storage facilities. Hydrocarbon Gas trunk lines operate at higher pressures than flow lines and could vary in size from 6 inches in diameter to as large as 4 feet. In order to design a suitable pipeline for transporting gas for the Agbada I and Agbada II Fields, the following methods were employed in this work; considering the minimum required parameters in the design of onshore and subsea pipelines but not limited to temperature of flow lines; pipeline pressure losses; gas composition and properties; desired mass flow rate; elevation at exporting terminal (FPSO); distance between exporting terminal and the receiving facility; Weymouth equation and Pipesim. In conclusion, the hydrate formation temperature obtained from the hydrate phase envelope at a defined pressure of 2 555 psia is approximately 73 oF, in flow line 1 and 2, as distance increases the pressure of 8 ins pipe, 10 ins pipe, 12 ins pipe and 14 ins pipe decreases. In flow line 1, as distance increases the flow rate of Gas 120mmscfd and Gas150mmscfd decreases, then increase exponentially and decrease with total distance and in flow line 2, as distance increases the flow rate of Gas 120mmscfd and Gas150mmscfd decreases, then remain constant with total distance. Finally, the increase in distance increases the parallel line capacity increases flow rate and the increase in distance increases the parallel line capacity increase flow rate.
