“…They found that neither objective alone is sufficient for a balanced process design by applying their framework to CO 2 mitigation in chemical processes and oil and gas plants (105)(106)(107). Pavão et al (108) also chose a derivative-free optimization approach, using a meta-heuristic approach with simulated annealing and particle swarm optimization, to synthesize a heat-exchanger network with minimum cost and environmental impacts.…”

Design in the chemical industry increasingly aims not only at economic but also at environmental targets. Environmental targets are usually best quantified using the standardized, holistic method of life cycle assessment (LCA). The resulting life cycle perspective poses a major challenge to chemical engineering design because the design scope is expanded to include process, product, and supply chain. Here, we first provide a brief tutorial highlighting key elements of LCA. Methods to fill data gaps in LCA are discussed, as capturing the full life cycle is data intensive. On this basis, we review recent methods for integrating LCA into the design of chemical processes, products, and supply chains. Whereas adding LCA as a posteriori tool for decision support can be regarded as established, the integration of LCA into the design process is an active field of research. We present recent advances and derive future challenges for LCA-based design. 203 Annu. Rev. Chem. Biomol. Eng. 2020.11:203-233.

“…Further, Onishi and co-workers developed a larger superstructure with several work-exchange options . The incorporation of environmental impacts to the HEN synthesis problem was assumed in the works of Pavão et al, who handled that objective along with economic aspects via multiobjective optimization (MOO), Mano et al, who approached the problem converting environmental impacts into monetary units, and Onishi et al, who also employed MOO techniques for assessing environmental and economic performances in work and heat integration. Verheyen and Zhang considered uncertain temperatures and flow rates in HEN, presenting a model for multiperiod HEN synthesis based on the SWS of Yee and Grossmann .…”

Several methods for heat exchanger networks (HEN) design are based on the use of superstructures. The models they give rise to can lead to different design options to be explored in HEN synthesis. In this work, a stage-wise superstructure with new features for the optimal placement of heaters and coolers, including the possibility of the use of multiple utilities, is presented. In the model, those units can be placed in different stream split branches in all stages, differing from the usual allocation at stream ends. Such possibilities yield a more complex mathematical model. To solve it, an improved version of a previously presented hybrid meta-heuristic method was used. Three examples from the literature were studied. The use of the superstructure with the additional utility-related options, as well as the enhanced meta-heuristic solution method, led to configurations with lower associated total annual costs than those reported in previous works.

“…In addition, Figures – were optimized using the NNM with stream splits, while Figures and were obtained using the NNM without stream splits. The lowest TACs reported in the literature for cases 1–3 with stream splits are 1,497,325$/yr, 6,712,551$/yr, and 1,462,323$/yr, by Pavão et al, Pavão et al, and Bao et al, respectively, while for cases 3 and 4 without stream splits, the lowest TACs are 1,403,581$/yr and 1,925,783$/yr by Xiao et al, respectively. It can be clearly seen from Table that the TACs obtained using the NNM for cases 1–3 with stream splits are 0.16, 0.34, and 2.97% lower than those reported in the literature, respectively, while in cases 3–4 without stream splits, the obtained TACs are 0.1 and 0.6% lower than those reported in the literature, respectively.…”

Obtaining precise and efficient solutions of large-scale cases is one of the main obstacles of heat exchanger network synthesis (HENS) technologies. Due to the absence of abundant local minima in the solution domain, searching a sufficient solution domain and decreasing the amount of calculations are two vital tasks for finding a globally optimal solution for HENS. In order to address the above-mentioned problems, a flexible model with an adjustable number of nodes is developed in this paper. In the premise of sufficient solution space, the developed model dynamically adjusts the number of calculation nodes during the optimization process based on the current configuration. The effectiveness of the developed model is demonstrated and verified using four large-scale cases with different conditions. The obtained results demonstrate that the optimal solutions produced by the proposed model for cases 1−3 with stream splits are 0.16, 0.34, and 2.97 better, while for cases 3−4 without stream splits are 0.1 and 0.6% better than the best optimal solutions reported in the literature, respectively. Moreover, the computational times for cases 1−3 are 29.5, 44.86, and 51.8% lower, while for cases 3−4 without stream splits are 25.20 and 25.24% lower than the ones without the proposed method, respectively. In addition, the overall computational efficiency of the proposed model can be improved by a maximum of 51.8%.
