“…Targeting techniques have been developed to identify minimum usage of fresh resources using a cascade diagram (Manan et al [10]) and using pinch-based composite representations (El-Halwagi et al [11]). Mathematical programming techniques have also been used to solve the recycling/reuse problems [12,13], including multicomponent systems (see, for example, Alva-Argeaz et al [14], Benko et al [15], and Dunn et al [16,17]). Additionally, similar methods have been developed for unsteady-state and batch systems (see, for example, Wang and Smith [18], Almato et al [19], and Zhou et al [20]).…”

“…To aid solution convergence, additional 21 constraints are included on maximum wastewater flows and on forbidden stream matches, 22 which eliminate uneconomic small flowrates between operations to simplify the network. 23 However, the approach does not guarantee a global optimal solution. 24 25 1998: First MINLP formulation (Galan & Grossmann) 1998: Incorporation of pinch analysis in optimization (Alva-Argáez et al)…”

9 10Increasing water demand in the process and its allied industries coupled with global water stress 11 and scarcity has underlined the importance of water as a crucial resource and elevated a need for 12 widespread adoption of water reuse and recycle. This paper provides a state-of-the-art review of 13 the area of water network synthesis focusing on single-site continuous process problems since its 14 inception in the 1980s. The survey centers around model-based optimization or mathematical 15 programming methods for water network synthesis and covers key findings from the water pinch 16 analysis technique, which are often essential in enhancing model formulations. Major modeling 17 and computational challenges are discussed that explore the issues of nonconvexity, nonlinearity, 18 and uncertainty inherent in

“…Even though it seems like a separate area of research, the problem is a mass exchange problem. Indeed, contrary to recent claims (Alva-Argáez, Vallianatos & Kokossis, 1999), although some processes are not countercurrent mass exchangers, it can be modeled as a one lean stream (water) and many rich streams (processes) system.…”

“…Therefore, the objective may now depart from the minimization of fresh water consumption to include the aforementioned costs. Even though, retrofit options have been mentioned in several papers, (Alva-Argáez et al, 1999;Huang et al, 1999), pumping costs have not been included and heat integration is absent. One attempt to address the problem directly has been recently done by Bagajewicz, Savelski and Rodera (1999b) and Bagajewicz et al (2000b).…”

This paper presents a review of the procedures to design and retrofit water networks. Although the emphasis is in showing results for refineries, the methods are valid for any process plants. It is first shown that the problem has been decomposed into the design of two interacting subsystems. One problem is the freshwater and wastewater reuse allocation and the other is the wastewater treatment problem. It is also shown how the wastewater treatment problem was modeled as a distributed and decentralized treatment. The roadmap towards zero liquid discharge and energy integrated solutions is then discussed. Several solution approaches are briefly outlined emphasizing the main trend leaning towards the use of mathematical programming. The major claim made is that mathematical programming can produce globally optimal solutions and practically important sub-optimal solutions when conceptual insights are employed to build the models. Although the paper intends to be comprehensive, it emphasizes the author's recent work. Finally, a few of the existing challenges of the area are outlined.
