CLOSED LOOP DYNAMIC OPTIMIZATION OF PRODUCTION PLANTS

Realtime economical optimization of production plants has traditionally relied on steady state process models. Because real plants are normally in transient states, such models could be adapted to measurements only occasionally. Neste Jacobs Oy has developed a new closed loop dynamic realtime optimization (DRTO) technology, which optimizes the plants also during transient states. The technology permits optimization practically in realtime, which contributes to quickly reaching optimum. The DRTO application example is in the Ethylene Plant of Borealis Polymers Oy, Porvoo, Finland. The DRTO is in continuous use since 2004 and the experience has been outstanding.
