Web2. Decompose the network at the pinch into two subsystems, above and below the pinch, and commence the synthesis at the pinch. 3. Just above the pinch the following conditions must be met to have a feasible match. CP hot ≤ CP cold N hot≤ N cold On the other hand, just below the pinch CP hot ≥ CP cold N hot≥N cold WebTwo major approaches have been developed for optimal synthesis of heat exchanger network: pinch technology ( Itoh et al., 1982; Kemp, 2007; Smith, 2005) and mathematical programming methods ( Biegler et al., 1997 ). Mathematical optimisation methods for HEN synthesis can be classified as sequential and simultaneous approaches.
