An economic value chain lifecycle model [LCM] is presented for minimizing carbon foot print, capital utilization and environmental impact categories to justify investment in a proposed Natural Gas pipeline and 300MWD Power Plant infrastructure availability for a National Gas Company. The model was developed to assist private gas off takers venture capital investors evaluate and justify feasibility of investment in Nigeria State Gas pipeline and power plant projects to meet commercial production of power and pipeline availability based on economic and environmental sustainability demand vector metrics. The demand vectors investment simulations in MATLAB environment show economic over environment sustainability performance on a final demand vector of 3,597 x106 USD against an actual target of2,769.78 x106USD. Thus the Monte Carlo simulation probability model data to assess sensitivity in actual demand vector was generated by random variables of environmental intervention units of the economic impact categories. The simulated data was used to determine the gas pipeline and power plant investment sensitivity analysis of the final demand vector of Gas pipeline and power plant production units in Lifecycle chain. The simulated results showed that carbon footprint credits targets were within acceptable range to justify environmental sustainability of the projects.NOX averaged value of 30.48 ppm below environmental regulatory limit of 65.97 ppm. The LCM demand vector and environmental intervention matrix simulation was simulated at a 7% net impact value on net return on investments with about 22% environment intervention impact units.&nbsp;&nbsp;The previous studies of emissions and carbon prints from electricity generation &nbsp;indicated that indirect GHG emissions from gas pipeline availability projects may represent 25% of overalls value is higher for renewable technologies. The gas pipeline availability should have investment and economic performance on the assumption that various possible sources of gas and technology option for private up takers will be available. Final recommendation to the gas projects investors, up takers, operators, policy formulators and regulators suggest any technology that minimizes the greenhouse gases CO2, gas plant should be within accepted limits of&lt;10ppm for planned future GHG and carbon footprint. The simulation result show that Gas projects impact categories of 79% for global warming, 9% for Sulphur (IV) oxide and carbon monoxides and carbon dioxides acidification and 0.001% to ozone layer depletion is not acceptable within the framework and targets set by the world Kyoto climate change protocol where Nigeria is a treaty member and any sustainable Gas projects must incorporate reducing the carbon foot prints.&nbsp;

ASME 2021 International Mechanical Engineering Congress and Exposition (IMECE2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
