Optimal grade transition campaign scheduling in a gas-phase polyolefin FBR using mixed integer dynamic optimization Academic Article uri icon


  • Transitions between different polymer grades are becoming part of day-to-day modus operandi for polymerization processes in the polymer manufacturing industry for multiproduct requirements with diverse specifications. An integrated approach to the optimal production scheduling, while accounting for the optimal grade transition profiles is carried out in this work using recently developed state of the art Mixed Integer Dynamic Optimization (MIDO) techniques. A remarkable improvement on process economics is observed in terms of the off-spec production and the overall transition time. 2003 Elsevier B.V. All rights reserved.
