Abstract
Since the eco-efficiency of all industrial processes/plants has become more and more important, engineers need to find a way to integrate control loop configuration and measurements of eco-efficiency. In this paper, we present the relative exergy destroyed array (REDA), a new tool to measure the relative eco-efficiency of a process. The REDA is a means to compare eco-efficiency of multi input-multi output processes for different combinations of control structures. Although based on steady state information, it is a simple tool for comparing eco-efficiency of a process with several process control structures. The results obtained from the REDA are interpreted and explained with the help of a simple case study. REDA will help guide the process designer to find a quick optimal control design with low operating cost/eco-efficiency.
