Pinch analysis and process integration techniques are established methods to increase process heat recovery, thereby limiting overall plant energy requirements. Pinch analysis proceeds in two basic steps: 1) targeting possible energy savings, and 2) developing design based on pinch principles to achieve the identified targets. To attain the defined targets, changes to the heat exchanger network (HEN) may be extensive and complicated. Such excessive changes may lead to extremely high costs and hamper the feasibility of the project.
