Key issues:

• Reduce risk of “will it work” uncertainty.
• Component sizing and matching off the shelf components.
• Determine workable start up procedure.
• Prove concept within time and cost constraints.
• Controllability of the plant – during load following.

Methodology:

• From mass and energy balance create Dynamic Flownex model.
• Components were evaluated at design and off design conditions – Load following transients.
• Start up sequence were planned and risks addressed.

Solution:

• Understand system dynamic behaviour.
• Proof of concept in time and budget  (Cost saving of $48M)!
