Production of Electricity from Flared Associated Gas as a Strategy for Reduction of Environmental Pollutions in Oil and Gas Sector (A Case Study of Niger Delta)
International Journal of Oil Gas and Coal Engineering
The flaring of associated gas has become a global challenge. Aside the financial implication resulting from associated gas flaring, the environmental consequences are enormous and poses great threats to humans and the underlying ecosystem. The environmental implication is the degradation of the ecosystem resulting to loss of ecological lives, emergence of sicknesses, air, water and land pollution, release of poisonous gases that hamper human habitation, release of greenhouse gases resulting to
... gases resulting to global warming, severe respiratory diseases like asthma, bronchitis have been linked to flaring of associated gas in the host communities. The goal of the world health organization to completely eradicate gas flaring by 2030 has forced many countries to make laws that favour the utilization of associated gas and the further development of gas projects. Costly gas projects have undergone technological improvement, miniaturization and scaling to become portable and profitable ventures. In this paper, we propose means of utilising and monetising the flared associated gas in generation of electricity by a method known as gas-to-wire, this is the process of generating electricity from natural gas at or near the proximity of the field. The produced electricity is supplied to nearby host communities while surplus is supplied to the main electricity grid. Izombe production sites have been taken for case study. The turbine system used is a combined cycle gas turbine with a daily gas feedrate of 40MMscfd. The technical and economic parametres relative to the project are analyzed and discussed. The project promises a potential solution to the Nigeria electricity problem by diversification of electricity production and distribution and reduction in over-reliance on national grid.
