Effect of Delta Temperature Minimum Contribution in Obtaining an Operable and Flexible Heat Exchanger Network

This paper presents the control structure decision making for heat exchanger networks (HENs) to obtain operable and flexible network. Delta temperature minimum (ΔTmin) contribution is considered in this study. Several studies have been done to determine the effect of ΔTmin-contribution on the annual...
