“…insight-based pinch analysis techniques such as heat transfer composite curves (Hohmann, 1971;Umeda et al, 1978;Umeda et al, 1979), problem table algorithm (Linnhoff and Flower, 1978b;Linnhoff and Flower, 1978a), pinch design method (Linnhoff and Hindmarsh, 1983;Ahmad et al, 1990;Linnhoff and Ahmad, 1990;Linnhoff, 1993), dual temperature (Trivedi et al, 1989a) and pseudo-pinch methods (Rev and Fonyo, 1986b;Rev and Fonyo, 1986a;Trivedi et al, 1989b;Wood et al, 1991) and (ii) mathematical programming techniques (Cerda et al, 1983;Papoulias and Grossmann, 1983;Floudas et al, 1986;Suaysompol and Wood, 1991;Ježowski and Friedler, 1992;Galli and Cerda, 1998a;Galli and Cerda, 1998b;Galli and Cerda, 1998c). The following section mainly focuses on reviewing the minimum utility targeting problem with sequential synthesis approach.…”
