Summary for the GG1 example simulation

Centrifugal compressors that are employed in gas processing plants and in gas pipeline transmission systems provide a vital function to the overall plant operation, and therefore must ensure a high level of operational reliability. It is essential to design these compressor systems in a manner that eliminates or minimizes potential for surge, which is a dynamic instability that is detrimental to the integrity of the unit.

The objective of this simulation is to:

• Determine the appropriate valve and pipe sizing required for anti-surge protection.

• Validate the anti-surge control strategy for upsets like motor trip or blocked outlet scenarios.

• Determine the maximum compressor outlet temperature during upset situations.

The following figure shows the Dynamic Compressor system modeled in AVEVA Process Simulation.
