Liquefied natural gas (LNG) will contribute more in the future than in the past to the overall energy supply in the\r\nworld. The paper discusses the application of advanced exergy-based analyses to a recently developed LNG-based\r\ncogeneration system. These analyses include advanced exergetic, advanced exergoeconomic, and advanced\r\nexergoenvironmental analyses in which thermodynamic inefficiencies (exergy destruction), costs, and environmental\r\nimpacts have been split into avoidable and unavoidable parts. With the aid of these analyses, the potentials for\r\nimproving the thermodynamic efficiency and for reducing the overall cost and the overall environmental impact are\r\nrevealed. The objectives of this paper are to demonstrate (a) the potential for generating electricity while regasifying\r\nLNG and (b) some of the capabilities associated with advanced exergy-based methods. The most important\r\nsubsystems and components are identified, and suggestions for improving them are made.
