This paper presents a novel thermodynamic analysis tool, the energy-flow framework diagram (EFD), and proposes a new method called the EFD graphic analysis method. It is a visual method of energy analysis and integration and is fairly convenient to analyze variety of complicated information,...

Using the first and second laws of thermodynamics, we describe an effective analysis of exergy loss for energy conversion in chemical or power-generation systems and explain the energy-utilization diagrams which are generated by a graphic simulator. Two types of advanced LNG powerplants, the...

A loop of chemical reactions is introduced to reduce the exergy loss caused by the conversion of fuel energy to thermal energy in conventional LNG powerplants. By applying this chemical loop and the graphic simulator which generates energy-utilization diagrams, a new gasturbine power-generation...
