An analytical model to study the dynamic response of heat exchanger network

An analytical model for the heat exchanger network (HEN) has been proposed in this work to study dynamic performance of HEN design stage. The relies on Laplace transform obtain system outlet temperature function when facing operational changeover. Equipped with decomposition strategy and pathway analysis, can reach time domain an easy way free numerical difficulty concern caused by inverse process that may occur toward complicated expressions. potential bias illustrated both static aspects changing conditions a exchanger. applied four streams synthesis problem investigate trade-off result between economic cost response time. Moreover, comparison simulation selected HENs shown act as pre-selection tool predict various during
