In this paperwork, a novel methodology of entropy generation minimization (EGM) for counter-current and cocurrent heat exchangers is developed. The methodology can be applied in general case for all types of the heat exchangers with the counter-current and co-current flow configuration. A number of entropy generation units (NEGU) function, along with its pressure drop and temperature difference components, are presented. Additionally, evaluated EGM can be easily incorporated into some optimization algorithms for industrial practice. Beside of the theoretical background, on an example and case study were proved that the EGM analysis could be useful in practical applications of heat exchanger optimization. Furthermore, the correlation between the minimum value of NEGU and minimum of total annual costs (operational and investment costs) have been shown. Based on the EGM methodology, on a case study was presented that pressure drop of the plate countercurrent heat exchangers in series shou...ld be 36 kPa, in order to achieve minimal annual costs of the 456 EUR/year. The result corresponds to the heat exchangers in series with 2 sections and 46 plates per section.
