Abstract
In this contribution we analyze an industrial multicomponent depropanizer m odel and show how to rewrite the original model to index-one formulation th at is well adapted to dynamic optimization. The optimal control problems ar e then studied with the aim of determination of the optimal output trajecto ries for minimum changeover time requirements. These can be utilized as set points for the existing real plant control. (C) 1999 Elsevier Science Ltd. All rights reserved.
