Simultaneous optimization models for heat integration—I. Area and energy targeting and modeling of multi-stream exchangers

Chemical engineering systems modeling and efficiency analysis of heat and mass exchange

“…In the 90s of the last century, an attempt to develop generalized representation about engineering systems, named as Heat Exchanger Network (HEN) and Mass Exchanger Network (MEN) [1][2][3][4].…”

The synthesis of cost optimal heat exchanger networks with unconstrained topology

“…It features a large number of units (n EX =15), since the objective function has a linear dependence from heat exchanger surfaces. Note that network topology cannot be derived from the stagewise superstructure proposed in [14], because one of the branches of stream H4 is matched to two cold streams (C1 and C2). The comparison with other solutions from the literature, proposed in Table 6, shows that the HEN in Figure 10 is cheaper than the other solutions because of the apparently lower hot and cold utility requirements.…”

“…Actually, under these hypotheses the resulting possible configurations are only a subset of those embedded in the stagewise superstructure proposed by Yee and al. [14].…”

“…• Jezowski et al [21] • Ponce-Ortega et al [24] and Luo et al [25] use the stagewise superstructure suggested by Yee et al [14];…”

“…Lin and Miller [18] apply tabu search, a meta-heuristic approach that is suitable for combinatorial optimization problems, to the stagewise superstructure by Yee et al [14] exclusively. Tabu search consists in a memory-based neighbor search approach which guides the process using a list of the tabu (forbidden) moves to keep track of search history.…”
