CONTROL LOOP CONFIGURATION AND ECO-EFFICIENCY

Since the eco-efficiencies of all industrial processes/plants have become more and more important, engineers need to find a way to integrate control loop configuration and measurements of eco-efficiency. A new measure of ecoefficiency for control loop configuration was developed, the exergy efficiency factor. The exergy efficiency factor is based on the thermodynamic concept of exergy which can be used to analyze a process in terms of its efficiency. The combination of the Relative Gain Array (RGA) and the exergy efficiency factor will help guide the process designer to reach the optimal control design with low operating cost. The proposed method is validated by dynamic simulation.
