Material recycle pinch diagram

The material recycle pinch diagram is a graphical procedure for targeting the minimum amount of fresh feed usage and waste discharge as well as the maximum possible recycle... 

Figure 6.8 The shifted material recycle pinch diagram for Table 6.2.

The source composite curve in Figure 6.A.1 has not been shifted. To determine the minimum amount of fresh feed usage and waste discharge as well as the maximum amount of recycle, the user has to move the source composite curve horizontally until the sink composite curve touches the source at the pinch point and the remainder of the source composite curve exists entirely to the right of the sink composite curve (that is, curves cannot overlap). Pinch point is the point where the load of recycled sources matches with that of the sinks [18]. Figure 6.8 shows the shifted material recycle pinch diagram.
