  6. Cracker Steam Net From production HP To PE Boilers MP From LD5 New New LP Dump To processes

  7. Trip of LD5 From production To PE Boilers From LD5 Dump To processes

  8. Trip of LD5 From production To PE Boilers From LD5 Dump To processes

  9. Trip of LD5 From production ? To PE Boilers ? Major pressure drops ? From LD5 Dump To processes

  10. Pressure Control From production To PE Boilers From LD5 Dump To processes

  11. Findings • Restrictions necessary on the PE site to slow down the course of events.

  12. Findings PI PI PI • Restrictions necessary on the PE site to slow down the course of events. • Use the same measuring point for all control loops in the LP net.

  13. Findings • Restrictions necessary on the PE site to slow down the course of events. • Use the same measuring point for all control loops in the LP net. • Feed forward needed in boiler control Acceptable pressure range t0

  14. Findings • Restrictions necessary on the PE site to slow down the course of events. • Use the same measuring point for all control loops in the LP net. • Feed forward needed in boiler control • Dynamic simulations necessary prior to mayor changes.
