Pinch analysis has become a mature tool for the design of heat exchanger networks. Moreover, it has developed from a specialist tool for heat recovery into a broader based methodology for the conceptual design of process and energy systems. The material covered in this hand book has been restricted to the design of heat exchanger networks. The reader should not consider that the material covered here is comprehensive. It is only an introduction. To realise the full potential of Pinch Analysis requires consideration of methods for process changes, capital cost reduction, emissions reduction, debottlenecking, batch process design and total site integration Linnhoff (1993), Linnhoff (1994).

The major contribution of Pinch Analysis is in analysis rather than network design. Targets are analysed prior to design. This allows the designer to scope and screen design strategies. The scoping and screening considers overall economics (not just energy costs) and key feasibility features. Strategic alternatives can be selected for large and seemingly complex design problems.

In essence, Pinch Analysis reduces trial and error and provides insight in conceptual process design.
