Pinch analysis by temperature interval method and grand composite curve

Example 4.30 Pinch analysis by temperature interval method and grand composite curve Table 4.23 shows hot and cold streams. 

Heats of hot streams (kW) Temperature intervals (°C) Heats of cold streams (kW) Grand composite curve (kW)  

Available Cascaded Thot H2 HI C2 Cl Tcold Required Cascaded Net q = Cascaded Adjusted T 

However, between 150 and 145°C, we consider both the hot streams H2 and HI, and we have 

Hdei =HLmm-HVmm+HD (before the feed stage) (4.245)
