Abstract

Operability studies are suggested to provide additional insight into the synthesis of heat exchanger networks (HEN). It is well established that resiliency is largely a function of the structure of the network. Therefore, operability considerations help the designer to efficiently cover the extra degrees of freedom in the design away from the pinch. Finally, there is one more important piece of information that operability analysis offers as a bonus. It concerns the control structure of the network. Operability conditions identified from the suggested analysis clearly dictate an efficient control structure to dispose of a disturbance entering the network. The present work attempts to treat all classes of parameter variations (supply and target temperatures and heat capacity flowrates) with a unified approach.
