Example H22C17
This example was first used by Bjork and Pettersson (2003). It is the largest
heat exchanger network available in the literature and being investigated by
many researchers. The problem data are listed in Table 6.35. We used the

Table 6.35 Problem data for H22C17 (Bjork and Pettersson, 2003).
