Heat Exchanger Network Design—Summary

A good initialization for heat exchanger network design is to assume that no individual exchanger should have a temperature difference smaller than AT n. Having decided that no exchanger should have a temperature difference smaller than two rules were deduced in 

If the energy target set by the composite curves (or the problem table algorithm) is to be achieved, there must be no heat transfer across the pinch by 

The design of heat exchanger networks can be summarized in five steps  

Divide the problem at the pinch into separate problems.
