    abstract = {Thermoeconomic evaluation aims at diagnosing the malfunction of energy systems and at optimizing
their structure and performance. One of the main limitations of this approach is the adequate treatment of
dissipative components, i.e., components where exergy is destroyed without gaining thermodynamically useful
output (condensers, throttling valves, etc.). Such components are constituents of some energy systems and
influence their overall thermal efficiency. This research introduces the use of a different criterion of exergy
efficiency to assess dissipative components. In this case, it is possible to define the efficiency of dissipative
components without the introduction of negentropy flows. As case study, a Rankine cycle discussed in
literature is selected. The different approaches to evaluate dissipative components are applied and compared
with the proposed one. Results show that with the proposed approach it is possible to evaluate dissipative
components in isolation avoiding the inconsistencies resulting from the use of negentropy flows in the
assessment. The introduction of negentropy flows also increases the complexity of the assessment.}
