Heat exchanger network pinch design method

The pinch analysis method provides the targets for the Heat Exchange Network (HEN) designs of the examined process. This HEN design problem is complex and involves combinatorial problems in the pairing between the hot and cold streams to enhance the heat recovery [28]. HEN design is one of the most fundamental activities in the process design procedure as it is considered as sub-synthesis problem of the overall synthesis problem.

The use of the pinch technology method in the design of heat exchanger networks has been outlined in Sections 3.17.1 to 3.17.6. The method can also be applied to the integration of other process units such as, separation column, reactors, compressors and expanders, boilers and heat pumps. The wider applications of pinch technology are discussed in the Institution of Chemical Engineers Guide, IChemE (1994) and by Linnhoff et al. (1983), and Townsend and Linnhoff (1982), (1983), (1993). 

The pinch design method creates a network structure based on the assumption that no heat exchanger should have a temperature difference smaller than ATmin. Having now created a structure for the heat exchanger network, the structure can now be subjected to continuous optimization. The constraint that no exchanger should have a temperature...

In the 1980s, there was a great deal of research into design methods for heat exchanger networks see Gundersen and Naess (1988). One of the most widely applied methods that emerged was a set of techniques termed pinch technology, developed by Bodo Linnhoff and his collaborators at ICI, Union Carbide, and the University of Manchester. The term derives from the fact that in a plot of the system temperatures... 

The systematic procedure for designing the Heat Exchanger Network based on Pinch principle is designated as the Pinch Design method (Linnhoff et al., 1978, 1983). The methodology consists of the following steps ...

Be able to design networks of heat exchangers on the hot and cold sides of the pinch, to meet the MER targets, using the heuristic method of Linnhoff and Hindmarsh (1983) or the transshipment model in a MILP.
