New Pinch Technology Based HEN Analysis Methodologies for Cost-Effective Retrofitting

Journal article, 2001

In this paper, new pinch technology based curves for retrofitting of heat exchangers are presented. Advantages compared to traditional pinch curves, and the information that can be extracted from these curves, are discussed. The curves have been applied to an example where different energy saving levels has been studied. The results have been verified by detailed calculations using the Matrix method.
