A New Graphical Methodologey for Energy Integration in Power Plants
Pinch Analysis, Exergy Analysis and Optimization have all been used independently or in combination for the energy integration of process plants. In order to address the issue of energy integration, taking into account composition and pressure effects, the concept of energy level. We have developed a strategy for energy integration that uses power plant simulation tools to define the interaction between the various subsystems in the plant and a graphical technique to help the engineer interpret the results of the simulation with physical insights that point towards exploring possible integration schemes to increase energy efficiency. The proposed graphical representation of energy levels of processes is very similar to the Composite. Curves of Pinch Analysis Energy Level Composite Curves reduces to the Pinch Analysis case when dealing with heat transfer.
