Abstract

In this paper, a life cycle model [LCM] is presented to quantify the economic value chain, green houses gases [GHG], carbon footprint and environmental impact categories of a three hundred megawatts (300MW) natural gas power plant operated in Lagos Nigeria. The LCM evolved from the linear space concept where the process flow units of the
power plant are partitioned into economic and environment matrix system based on the final demand vector. The GHG footprints are based on its current technology value chain (raw materials and energy utilization) measured against environmental targets. The results shows that higher water injection rates to the cooling unit of power plant turbine
tend to reduce GHG and other pollution gases from natural gas power plant to within accepted limits. The simulation results show impact categories from power plant operations to be 79% for global warming and 89% for Sulphur (IV) oxide acidification pollution. The Monte Carlo simulation run shows a strong correlation from stochastic generated
values of 22% environmental impact units and 2% net impact.
