Heat exchanger network synthesis can be facilitated by using an optimised data set for the initial design. Crisscross optimisation prior to design is an excellent tool to generate such data set.

There is no such thing like an optimum DTMin or Heat Recovery Approach Temperature HRAT nor any Exchanger Minimum Approach Temperature EMAT to be considered; there only is optimum integration combined with optimised crisscross.

The pinch analysis introduction package "Heatit - Basic" is available free of charge. 

Example studies marked as [SECURE] can be downloaded without any restriction, provided you are so kind to identify yourself to the author.
