Pinch analysis is a systematic technique for analyzing heat flow through an industrial process, based on fundamental thermodynamics. It incorporates a range of tools of which the best known are the hot and cold composite curves, which represent the overall heat release and heat demand of a process as a function of temperature. By using these tools appropriately it is usually possible to identify opportunities for process heat recovery that are missed when other methods are used. This can save millions of dollars per year in energy costs, often with little or no increase in capital investment.

This webinar introduces the basic principles and tools of pinch analysis and shows how they can be applied in real-world applications. An extensive case study is presented to illustrate how to use the pinch approach to revamp an existing heat integration system.
