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 minimum number 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 ...
