Abstract
Heat exchangers are essential elements used in a wide range of engineering applications. Heat Exchanger Networks (HEN) synthesis and optimization is an important field in process integration and different objective functionshave been used to calculate the network total annual cost. This paper presents a comprehensive review in terms of the published literature on HEN cost calculations, highlighting papers related to the design and optimization of HEN. The main research in HEN’s parameters for total cost calculation and its contribution to how these costs are formed, through a systematic literature review is presented in the present paper. It can be noteda gap in this field indicating that apart from a few studies published after 2005 and despite the emergence of new studies on changes in HEN cost functions, the use of more traditional cost calculation models still prevails in the current literature. This review also identifies the current challenges regarding this research field through analysis and comparison. Finally, issues related to cost parameters of objective functions concerning HENoptimization are highlighted and scope for future research is discussed.
