            No stream split.

             After revision, HUC1 and the split of H1 are deleted.

             network was obtained by Pettersson (2005), using a sequential match
             reduction approach based on an assignment model for the synthesis of
             large-scale heat exchanger networks. The network has seven stream
             splits and contains 15 independent variables. As is shown in Fig. 6.27,
             the network is similar to a hyperstructure, and there is a sequential use
             of hot utility for the cold stream C5. The revised TAC is 2,892,924$/yr.
