Energy integrated networks, designed to reduce energy consumption, offer cost savings at the expense of challenging operation. Simple networks with energy integration, involving either a large recycle of energy or a large throughput of energy, have been shown to exhibit dynamic behavior evolving over two time scales. In this paper, the time scale properties in the dynamics of networks involving multiple, interconnected throughputs and recycle loops are investigated. A graph theoretic analysis framework is developed which allows identifying the time scales where each of the process units in the network evolves, based on knowledge of the order of magnitude of the energy flows in the network. An example network is considered to illustrate the application of the proposed framework.
