“…Ahmad obtained the minimum TAC using the pinch point method, which was USD 9,490,000/yr. Liu et al [37] used a hybrid genetic algorithm and achieved a minimum annual integrated cost of USD 8,917,245/yr for the final structure of this case. Additionally, Liu et al [38] used the RWCE algorithm with an improved step size to optimize the SWS model and obtained a minimum annual integrated cost of USD 8,707,983/yr for this example.…”

The non-structural model of heat exchanger networks (HENs) offers a wide solution space for optimization due to the random matching of hot and cold streams. However, this stochastic matching can sometimes result in infeasible structures, leading to inefficient optimization. To address this issue, a tabu matching based on a heuristic algorithm for HENs is proposed. The proposed tabu-matching method involves three main steps: First, the critical temperature levels—high, medium, and low-temperature intervals—are determined based on the inlet and outlet temperatures of streams. Second, the number of nodes is set according to the temperature intervals. Third, the nodes of streams are flexibly matched within the tabu rules: the low-temperature interval of hot streams with the high-temperature interval of cold streams; the streams crossing cannot be matched. The results revealed that by incorporating the tabu rules and adjusting the number of nodes, the ratio of the feasible zone in the whole solution domain increases, and the calculation efficiency is enhanced. To evaluate the effectiveness of the method, three benchmark problems were studied. The obtained total annual costs (TACs) of these case studies exhibited a decrease of USD 4290/yr (case 1), USD 1435/yr (case 2), and USD 11,232/yr (case 3) compared to the best published results. The results demonstrate that the proposed tabu-matching heuristic algorithm is effective and robust.

“…Brandt et al (2011) applied a heuristic step used to remove the heat load loops from the structure when profitable, which introduced the possibility of including specific heuristics to enhance the GA/SA performance. Liu et al (2014) adapted the algorithm to solve the retrofit problem. Finally, Xiao et al (2006) applied GA/SA and changed the optimization variables in order to apply the temperature-enthalpy diagram method to reduce the computational time of the algorithm in large-scale networks.…”

Heat exchanger networks (HENs) are a useful method of reducing the energy costs and environmental impact of industrial processes. Therefore, many papers focusing on solving HEN design problems efficiently have been published in the last years and several techniques have been proposed for their solution. The high complexity of the problem has led to an increment in the number of papers that use metaheuristics to solve it. The main reason is the capability of metaheuristics to handle complex problems in a feasible computational time. Additionally, this approach can easily take into account investment costs, and it offers more flexibility in the definition of the objective function and problem restrictions. In this paper, we review the most relevant papers that use metaheuristic techniques to resolve the HEN design problem. We also propose a method for grouping the different analyzed metaheuristics. It is based on a series of characteristics that allows the correct characterization of the different approaches.

“…To simplify the calculations, stream splitting was neglected and the number of heat exchangers on each stream was limited in his model. Liu et al removed the limitations imposed by Kovač Kralj and solved the improved model using a genetic algorithm (GA). Although the GA is able to deal with discrete variables, it is time-consuming in handling continuous variables.…”

Heat exchanger network retrofit problems in a multiperiod operation are commonly solved in a stepwise manner. The matching of heat transfer areas is generally used to finalize the retrofit after the determination of the retrofit target of the heat exchanger network. Conventional heat transfer area matching methods are either experience based or model based methods, which may lead to indeterminate solutions or scale limitations in the optimal matching strategy. In this work, a systematic approach and algorithms for matching heat transfer areas in a multiperiod heat exchanger network retrofit are proposed. The methodology is based on the reverse order matching method and the matching algorithms of a bipartite graph. The proposed approach achieves four main objectives: to maximize the number of substituted heat exchangers, to minimize the increases in heat transfer area, to minimize the investment cost after a retrofit, and to minimize the investment cost given the preference rankings restrictions of heat exchanger operation pressures. The heat exchanger network retrofit of a diesel hydrogenation unit in a multiperiod operation is employed to illustrate the procedure and advantages of the proposed method. The results obtained by the proposed method and the methods in the literature are compared and analyzed. The results indicate that the proposed method enables the practical matching restrictions and costs to be taken into account. In addition, the proposed method is simple and easy to implement, which is conducive to solving the problems of heat exchanger network retrofitting quickly and accurately.
