摘要：Water reuse/recycle is one of the key strategies in reducing the freshwater flow rate inthe process industries. The problem involves the allocation of internal water andfreshwater sources to process units considered as demands with the objective ofminimizing freshwater feed and wastewater discharge. However, several graphical andnumerical techniques have been developed to target freshwater flow rate. In this paper,we present a new rigorous numerical targeting approach to minimize the utilization offreshwater and identify wastewater streams ahead of detailed design of the recycle/reusenetwork. First, the problem is formulated mathematically to establish rigorous rules fortargeting and designing water network. Then, targeting algorithm is elaborated to makethis methodology more practical. The numerical technique is useful in locating pinchpoint, which provides insightful information on the utilization of freshwater,identification and discharge of wastewater streams. In fact, examples for both models offixed flow rate and fixed load problems are solved to illustrate the ease, rigor, andapplicability of the developed targeting technique. Hence, this technique is extended todeal with a combined problem of fixed flow and fixed load.
