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.

自90年代初以来，复合曲线（CC）和网格图（GD）一直是最流行的基于夹点分析技术进行大规模交换网络（MEN）目标和设计的图形工具。但是，CC有局限性，因为它基于复合物而不是组成与质量负荷（yM）图上的单个流来映射富流和贫流。因此，它不能直接用于网络设计。网络设计需要使用设计准则集分别进行开发。本文介绍了流组成与质量负荷图（SCMP），作为同时进行MEN定位和网络设计以克服CC和GD局限性的新图形方法。SCMP会显示收缩点，最大质量回收率和最小质量分离剂（MSA）目标。
