Una mejora en el Método Pinch

Abstract

Structuring heat exchangers networks (HEN) is one of the most important topics in the academic curricula and practical working of Chemical Engineering. Although the structuring strategy proposed by the Pinch method constitutes an effective tool in this field, in some cases, the method fails obtaining designs with minimum consumption of utilities. This work proposes a condition that allows to guarantee that minimum. One of the classic rules of the Pinch method turns out to be, in fact, a particular case of the condition proposed here. Demonstrative examples of the proposed methodology are included.
