1 Introduction
Heat exchangers are essential components in process technology. Therefore, the economic selection and design of heat exchangers plays an important role for the profitability of a process.
In this connection profitability means the ratio of income to costs. Income and costs are value quantities (monetary units per unit time) which are linked to the physical variables used in engineering by cost coefficients. Applying the notion of profitability to heat exchangers allows either to compare marginal cost and marginal utility of a transferred heat flow or to consider the amount of heat transferred during a period of time as an externally specified quantity. The definition of marginal values in economics is given by W. H. Bartzsch [1].
In the former case the increase in income (usually in the form of lower energy costs) must be compared to the additional cost for the higher amount of transferred heat or for heat integration (Chap. C5). The additional costs for increasing the...
