Chapter 15. Pinch Technology
What You Will Learn
• Pinch technology involves heat or mass integration.
• There are procedures for obtaining the “optimum” heat integration or mass integration network, and these methods are closely related.
• A method to design the minimum utility heat exchanger network using the minimumnumber of heat exchangers.
15.1. Introduction
Whenever the design of a system is considered, limits exist that constrain the design. These limits often manifest themselves as mechanical constraints. For example, a distillation of two components that requires 400 equilibrium stages and a tower with a diameter of 20 m would not be attempted, because the construction of such a tower would be virtually impossible with current manufacturing ...
