“…More recently, other pinch-based approaches have also been reported including the water surplus diagram (Hallale, 2002), which is an improvement of the water source and demand composite curve of Dhole et al (1996) and water cascade analysis (Manan et al, 2004). Overall, the main attraction of graphical pinch analysis arises from its ability to provide insights and guidance to the designer in terms of water network targets (such as freshwater and wastewater flowrates and the pinch location) prior to detailed network design (Shoaib et al, 2008). A key drawback of this technique is that it is limited to processes characterized by single contaminant.…”

“…Méndez et al (2006) realizaram uma revisão dos métodos de otimização empregados para programação da produção de processos em batelada. Além dos trabalhos já mencionados, têm-se recentes contribuições, dentre os quais: Chang e Li (2006), que estudaram a equalização ótima de vazão de efluentes e concentração de contaminantes em plantas batelada; Shoaib et al (2008) e Oliver et al (2008), que combinaram programação matemática com análise Pinch para sintetizar redes de água em processos em batelada; Gouws et al (2008) Immich et al (2007) apresentaram uma adaptação do método DFA para um processo em batelada. O procedimento foi comparado à técnica gráfica empregada por Majozi et al (2006).…”

RESUMO O gerenciamento de recursos hídricos tem sido um fator importante para a sustentabilidade dos processos industriais, visto que há uma necessidade crescente pelo desenvolvimento de metodologias voltadas para conservação e uso racional da água. O objetivo deste trabalho foi aplicar o método Diagrama de Fontes de Água (DFA), usado na definição de metas de mínimo consumo de água, a processos que operam em regime batelada. Foram gerados e avaliados cenários de reúso de correntes obtidos pela aplicação do método a partir de dados de quantidade de água e concentração de contaminantes nas operações. Foram apresentados dois estudos de caso com o objetivo de demonstrar a redução de consumo de água e da geração de efluentes, além de custos de tratamento final e de investimento em tanques de estocagem, em relação à configuração inicial. Os cenários mostraram-se bastante promissores, com reduções que alcançam 45%, em termos de consumo hídrico e geração de efluentes, e 37%, em termos de custos de tanques, sem a necessidade de processos de regeneração. Com isso, a técnica empregada mostrou-se relevante e flexível como alternativa às ferramentas sistemáticas voltadas para a minimização do consumo de água em processos industriais, exercendo importante papel em um programa de gerenciamento de recursos hídricos. Palavras-chave: reúso de efluentes; tanque de estocagem; síntese de redes de transferência de massa. Water conservation and reuse using the Water Sources Diagram method for batch process: case studies ABSTRACT The water resources management has been an important factor for the sustainability of industrial processes, since there is a growing need for the development of methodologies aimed at the conservation and rational use of water. The objective of this work was to apply the heuristic-algorithmic method called Water Sources Diagram (WSD), which is used to define the target of minimum water consumption, to batch processes. Scenarios with reuse of streams were generated and evaluated with application of the method from the data of water quantity and concentration of contaminants in the operations. Two case studies aiming to show the reduction of water consumption and wastewater generation, and final treatment costs besides investment in storage tanks, were presented. The scenarios showed great promising, achieving reduction up to 45% in water consumption and wastewater generation, and a

“…The TAC is the unique objective function in most of the problems reported in literature [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], but in this paper the TS for the batch water network is also included as an objective function, which is aimed to take into account an innovative definition of process intensification [61], especially in reference to the minimization of storage of hazardous substances, under this concept in this paper has been developed a model from which is possible to determine a relationship between the total annual cost and the total storage to show the results through Pareto curves that tradeoff these objectives.…”

“…Moreover, there have been reported several methodologies for synthesizing batch water networks based on the composition of the streams (see for example, Refs. [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44]); and recently the concept of state-task-network representation has been applied to solve efficiently short-term batch optimization problems [45][46][47]. More recently, some improved strategies for recycling and reusing process streams based on the concept of property integration have been developed [48,6].…”

a b s t r a c tThis work introduces a multi-objective optimization approach for the synthesis of batch water networks. In addition to concentration-based constraints, water characteristics and property-based constraints for the process sinks are considered. Since adjusting properties may require the use of hazardous chemicals, issues of process intensification to minimize the total volume of stored materials are considered along with economic objectives. The model includes logical constraints, time restrictions, mass and property constraints for the sinks and environmental requirements. Two case studies are solved to show the applicability of the proposed approach. The results show tradeoffs between the storage of hazardous materials and the network economics. The multi-objective solutions are illustrated through Pareto curves that enable the decision maker to select the solutions that strike the proper balances between the desired objectives.
