Abstract
Since the early 90’s, Composite Curves (CC) and the Grid Diagram (GD) have been among the most popular graphical tools for targeting and design of Mass Exchange Networks (MEN) based on Pinch Analysis technique. However, CC has limitations since it maps rich and lean streams based on composites instead of individual streams on the composition versus mass load (y-M) diagram. Hence, it cannot directly be used for network design. The network design needs to be developed separately using sets of design criteria. This paper presents Stream Composition versus Mass Load Plot (SCMP) as new graphical approach for simultaneous MEN targeting and network design to overcome limitations of CC and GD. The SCMP shows the pinch point, maximum mass recovery, and the minimum Mass Separating Agent (MSA) targets. The network design to achieve these targets can be obtained by graphically translating the SCMP curves into Mass Allocation Network and Targeting (MANT) diagram.
