Industries consume large quantities of energy and water in their processes which are often considered to be peripheral to the process operation. Energy is used to heat or cool water for process use; additionally, water is frequently used in production support or utility networks as steam or cooling water. This enunciates the interconnectedness of water and energy and illustrates the necessity of their simultaneous treatment to improve energy and resource efficiency in industrial processes. Since the seminal work of Savulescu and Smith in 1998 introducing a graphical approach, many authors have contributed to this field by proposing graphically-or optimization-based methodologies. The latter encourages development of mathematical superstructures encompassing all possible interconnections. While a large body of research has focused on improving the superstructure development, solution strategies to tackle such optimization problems have also received significant attention. The goal of the current article is to study the proposed methodologies with special focus on mathematical approaches, their key features and solution strategies. Following the convention of Jeżowski, solution strategies are categorized into: decomposition, sequential, simultaneous, meta-heuristics and a more novel strategy of relaxation/transformation. A detailed, feature-based review of all the main contributions has also been provided in two tables. Several gaps have been highlighted as future research directions.

“…Heat-Integrated Water Allocation Network (HIWAN) design has been extensively studied in the literature in recent decades [1][2][3][4][5]. Multiple water-and energy-related specifications of such systems have been addressed by the literature [5], including multi-contaminant problems [6] and interplant operations [7][8][9][10]. Several researchers have also proposed methodologies to incorporate other aspects of an industrial process in the pursuit of exploiting potential synergies between them.…”

Industrial operations consume energy and water in large quantities without accounting for potential economic and environmental burdens on future generations. Consumption of energy (mainly in the form of high pressure steam) and water (in the form of process water and cooling water) are essential to all processes and are strongly correlated, which requires development of systematic methodologies to address their interconnectivity. To this end, the subject of heat-integrated water allocation network design has received considerable attention within the research community in recent decades while further growth is expected due to imposed national and global regulations within the context of sustainable development. The overall mathematical model of these networks has a mixed-integer nonlinear programming formulation. As discussed in this work, proposed models in the literature have two main difficulties dealing with heat-water specificities, which result in complex formulations. These difficulties are addressed in this work through proposition of a novel nonlinear hyperstructure and a sequential solution strategy. The solution strategy is to solve three sub-problems sequentially and iteratively generate a set of potential solutions through the implementation of integer cut constraints. The novel mathematical approach also lends itself to an additional innovation for proposing multiple solutions balancing various performance indicators. This is exemplified with both a literature test case and an industrial-scale problem. The proposed solutions address a variety of performance indicators which guides decision-makers toward selecting the most appropriate configuration(s) among a large number of potential possibilities. Results exhibit that despite having a sequential solution strategy, better performance can be reached compared to previous approaches with the additional benefit of providing many potential solutions for further consideration by decision-makers to select the best case-specific solution.

“…To further improve heat integration, Ibrić et al included nonwater-consuming processes (e.g., reactor feed, waste gas or liquid). Recent studies focus on the optimization of interplant HIWRN using centralized interception units. , A major drawback of these heat integration models − is the use of a maximum operator in an equation, which makes it nondifferentiable. To tackle this problem, Tan et al , proposed the floating pinch method that eliminated nondifferentiability at the cost of integer variables.…”

Optimal synthesis of a heat-integrated water network (HIWN) accounts for the simultaneous conservation of energy and water resources. A significant amount of research work, ranging from complex nonlinear formulations to simplified linear models, has been carried out for the synthesis of HIWNs. The incorporation of interception units leads to additional water and energy conservation but results in nonlinear formulations for heatintegrated water regeneration network (HIWRN) synthesis. This paper proposes a linear mathematical formulation, based on the transshipment model, for the optimization of HIWRNs using distributed interception units. As a result of a reduced number of variables and the absence of nonlinearities, the convergence efficiency is enhanced. The use of distributed interception units allows the regeneration streams to maintain their temperatures, thereby saving a significant amount of energy. A three-stage sequential approach and a simultaneous strategy are proposed for HIWRN synthesis. Although the simultaneous solution strategy provides cost optimal results, the three-stage sequential strategy is preferred in areas dealing with water scarcity and intermittent supply. The solution strategy is applicable to single as well as multiple-contaminant problems for single pass interception units with a fixed outlet and fixed removal ratio (RR). The methodology is demonstrated through literature examples for both types of interception units.
