This value is obtained according to Fig. 9 of Floudas and Ciric (1989). The reported value of TAC
was obviously a mistake.

configurations, we have revised all the available results by the use of the
problem data in SI, as is listed in Table 6.28. It shows that the effort for
finding its global optimal design is just like an Olympic game. The best
network configuration so far was obtained by Pettersson (2008), which
has three independent variables for the three stream splits, as is shown
in Fig. 6.28. According to his reported TAC of 43,331$/yr, the
isothermal mixing of the splitting streams might be used. The local
minimal TAC of 43,314$/yr was obtained by Toffolo (2009).
