The present paper analyzes the energy dynamics of process networks and/or staged processes whereby the material recycle streams interconnecting the units/stages take on the additional role of energy carriers. In the presence of large energy input and output flows, the networks considered are shown to exhibit a dynamic behavior with multiple time scales, with the variables in the energy balance evolving over a short time horizon, and the variables in the material balance exhibiting both fast and slow transients. A singular perturbation analysis is employed for the derivation of reduced order models for the fast and slow dynamics. Finally, an illustrative example and numerical simulation results are presented.
