Abstract

Most methods developed for water minimization for batch processes were reported based on pinch analysis and mathematical programming. In this work, a recently developed P-graph methodology for direct water reuse/recycle is extended for batch water network. The model allows direct water reuse/recycle when water sources and sinks are both located in the same time intervals, or stored for later use through water storage tank. A literature example is used to demonstrate the extended model. The important feature of P-graph is demonstrated through alternative solutions for the batch water network, with different numbers of water storage tanks.
