Example H10C10
As a large-scale heat exchanger network, this example was used by Luo et al.
(2009), which was taken from Xiao et al. (2006) for the synthesis of heat
exchanger network using multistream heat exchangers. The problem data
are listed in Table 6.33. The best network shown in Fig. 6.33 was
obtained by Bohnenstaedt et al. (2014), which has one stream split and
five independent variables and reaches the minimum TAC of 1,716,695$/yr.
