Title: An Approach to Plantwide Optimization
Author: Nath, R.; Worsham, B. A.; Libby, D. J.
Abstract: Optimization of individual processing units as well as the energy systems has become common place in the processing industries (Ref. 1,2). Typically such optimizations are done piecemeal, with heavy reliance on the 'transfer prices' to link the various optimizations. Such optimizations usually lead to decision policies which are inferior. Superior results are obtained when the processing units and the plant energy system are optimized jointly, in which case the 'transfer prices' become superfluous. A MILP (Mixed Integer Linear Programming) based approach for plant wide optimization is presented. This approach has been successfully applied in Union Carbide, and this paper describes a specific application at one plant.
