6 Process systems with energy recycling
The previous chapters have concentrated on analyzing the material-balance dynamics of several classes of integrated process systems. We demonstrated that the dynamic behavior of the systems considered exhibits several time scales and described a method for the derivation of reduced-order models describing the dynamics in each time scale. Also, a hierarchical controller design framework was introduced, with distributed control of the fast dynamics and supervisory control of the dynamics at the systems level.
In what follows, we focus on the dynamic features associated with energy integration, a ubiquitous design feature in the process and energy industries. Energy-integrated designs are ...
