Generalized model for work and heat exchange network synthesis considering pressure drop effects

This work proposes a detailed superstructure to synthesize work and heat exchange networks (WHENs). The main objective of this generalized model is to evaluate the effect of pressure drops on heat exchanger design and the corresponding impact on process economics. The pressure drop modeling is perfo...

The main objective of this generalized model is to evaluate the effect of pressure drops on heat exchanger design and the corresponding impact on process economics. The pressure drop modeling is performed by considering that the process streams can pass through the shell or tube side of the heat exchangers according to the energy requirements of the networks.
