Methodology for the design and analysis of reaction - Separation systems with recycle. 2. Design and control integration

The simultaneous solution of the design and control problems of chemical processes represents a complex task, given that several aspects should be fulfilled (e.g., although a design can be considered to be feasible, when attempting to control it might not be possible, or the control configuration could be quite complex). The interaction between design and process variables also must be considered while attempting to outline a control configuration. The second part of this communication shows how, through a model-based methodology, it is possible to solve the design and control problems in a systematic way, leading to a full understanding of a chemical process. The Tennessee - Eastman (TE) problem has been selected to highlight the application of the model-based methodology in a plantwide problem.
