Enhancing Sustainability in Domestic Natural Gas Transportation And Usage In Nigeria: An Evaluation

This study evaluates the sustainability of domestic natural gas transportation and usage in Nigeria, focusing on diversification into Compressed Natural Gas (CNG) and Liquefied Petroleum Gas (LPG) for the transportation and domestic sectors. The research is motivated by Nigeria Liquefied Natural Gas (NLNG) company's 18% profit decline due to East Africa's offshore discoveries and US shale gas emergence. Using computer software applications like Aspen HYSYS v7.1, Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and Auto-CAD, the study: Assesses gas diversification capacity; Determines pipeline pressure distribution; Designs a 24’’ carbon steel pipeline; Simulates process separation of heavy hydrocarbons (C3 and C4) using HYSYS and P&ID Column. The research finds that 45% local utilization of natural gas, either industrially or domestically, can enhance Nigeria's GDP growth. The study recommends diversification into CNG and LPG, and investment in infrastructure and technology to enhance sustainability in Nigeria's natural gas sector.
