Reviewing case study 12S.2 product and process design principles: Synthesis, analysis and evaluation book

The industries often require heat exchanger network (HEN) that supports variations in the streams thermal capacity and temperatures. Therefore, the HEN project must consider the concepts of flexibility, controllability and resiliency. This paper presents a review of the case study 12S.2 proposed by Seider et al. (2009)for analysis of operability using the RGA and DC index. The results found are the diagonal coupling of controlled and manipulatedvariables and the desirable resilience, obtaining economically improved solution than the proposed by the authors.
