Question

What is called Supertargetting in Heat Exchanger Network Design? How Heat Exchanger Network Design can be done by paying attention to Supertargetting?

Answer 1

Heat exchanger network technique is a technique that can be used for saving energy. The maximum heat energy can be recovered by the pinch technology method. Super targeting determines the minimal value of heat demand and minimal allowed temperature difference in the heat exchangers. It helps to form a proper network design by providing adequate results by the temperature controlling in the heat exchangers. Two techniques would be used in heat exchanger network design by paying attention to super targetting. They are problem table algorithm and pinch design method. The combination of both these techniques is used for designing heat exchanger network. This method aims for the minimum energy solution so that maximum amount of energy can be saved by the process as the heat demand would be known to us by super targetting and due to that there will be less possibility of wastage of energy. The task is being achieved by understanding the pinch phenomenon and by that reason it is known as pinch design method.
