THE PROCESS ANALYSIS WITH REFERENCE TO TH E EFFICIENCY AND PERFORMANCE AS AN AUXILIARY AID FOR ENGINEERS

The exergetic analysis has found great acceptance, as it is in itself correct and elegant, although there exists the following dilemma, if a concrete process has to be considered in detail: Exergy Losses, in ge neral, do not correspond with the ''poenalized output losses'', and ex ergetic efficiencies do not correspond with the ''poenalized process e fficiencies': This is knowledge that one can find in any text-book; it does indeed not belittle, however, the fundamental usefulness of an e xergetic consideration. Consequently, there exists room for a problem- relevant process analysis. which is discussed in the following part. T his analysis is divided into an efficiency and a performance analysis. For the Latter one is shown that the performance Lass with reference to the single-aggregate results from the irreversible occurrence of th e actual process itself. No a-priori-determination of an ideally compa rable process is required.
