Different techniques for the synthesis of industrial water reuse/recycle networks have been developed in recent process integration research. These tools range from graphical pinch analysis approaches to mathematical programming models. The latter have the advantage of being flexible enough to incorporate various water network constraints, but in many cases these are often non-linear, thus making the identification of global optima difficult. Recent work has demonstrated the effectiveness of metaheuristic algorithms such as particle swarm optimization (PSO), for finding good solutions these problems. This work describes the use of a modified PSO for solving mixed integer non-linear programming (MINLP) models for water network synthesis. By incorporating a mutation operator for the binary variables in the model, the algorithm is able to escape sub-optimal network topologies and proceed towards better solutions than can be found with ordinary PSO. Two case studies involving water recycle/reuse are used to demonstrate the new design methodology. 相似文献

In this paper, a case study based on an industrial process of ethanol distillation was undertaken. It was aimed to improve the energy and water usage in the process. Pinch Analysis concepts were used to propose a new heat exchanger network and a study was undertaken to the water reuse. The minimization of wastewater is achieved through the exploitation of recycle and reuse opportunities by process modifications. Through these studies, a new streams circuit was obtained, which resulted in a lower consumption of steam and in a reduction in the volume of water collecting of 12 m3 to 1 m3 per tons of crushed sugar cane. Process changes and economical viability were presented. Two kinds of equipment were studied, cooling towers and aspersion tanks. 相似文献
