Abstract

Exergy accounting is important in a variety of applications, one of which is the proper costing of different utilities supplied as products either to outside consumers or to in-plant manufacturing processes from a common system. Other applications rely not only on the costs of products, but also on the cost of “energy” at the junctures between the various operations in a “process” or “energy-conversion” facility. These costs can then be applied to: 1.(a) engineering/economic decisions regarding the operation (and maintenance) of a system or system-component,2.(b) feasibility studies,3.(c) improvement of design concepts and comparison of alternatives,4.(d) optimal design, and5.(e) economic selection of system components at the system design stage or time of replacement or retrofit decision. These different applications are illustrated by the results of four case studies.
