A targeting methodology is proposed to determine the optimum loads for multiple utilities
considering the cost tradeoffs in energy and capital for heat exchanger networks (HENs) …

Most of the established methods for utility targeting in a heat exchanger network (HEN) are
mainly focusing on fixed stream conditions, where the flow rate, heat capacity, supply and …

A simple modification of the original problem table algorithm (PTA) to target the minimum
utility requirements in a heat exchanger network is proposed in this paper. The modified …

Supertargeting based on composite curves (CC) is widely used to determine the optimum
approach temperature (ΔTmin) that yields the minimum total cost for heat exchange …

A new approach has been developed for establishing cost-optimal targets for a heat
exchanger network (HEN). We formulate a mixed-integer-linear-programming (MILP) …

Heat exchanger network (HEN) synthesis methodologies aim at developing cost effective
designs with the best possible topology and optimal values of the decision variables …

The optimal design of heat exchanger networks (HENs) has a great influence on the
profitability of a plant. The optimisation is based on trade-offs between investment and …

An extension of the utility targeting procedure in the pinch method for heat exchanger
network synthesis is presented. The procedure is adequate for targeting the minimum utility …

It has been well-established that the energy and capital costs of a heat exchanger network
are both dependent upon the minimum allowable temperature approach Δ T min. As a result …

An important feature of heat exchanger network design is the energy—capital tradeoff. This
tradeoff has been regarded as complex due to the number of structural network alternatives …
