Anti-Surge Compressor Control in Action
Anti-Surge Compressor Control in Action

9/5/2014, · The anti-surge control strategy is tightly integrated with the compressor load control strategy. The control strategy requires not only a fast acting controller, but a fast acting valve to release or recirculate the flow.

Anti-surge protection system for compressors ...
Anti-surge protection system for compressors ...

Anti-surge protection system is a very important part of compressor but it is not presented in anti-surge valves only but it contains a several devices that integrate all together to give an output which is the safe protection set-point for machine.

Anti-surge systems for axial compressors - Turbomachinery ...

This involved ramping open the ,anti-surge, valves at the initiation of a process shutdown. The appropriate ramp target and ramp rate of these recycle valves should be tuned using dynamic simulation. This should be activated by a process trip signal, and the ,anti-surge, valves would be ramped open to more than 60% for the axial flow compressor within two seconds.

Surge in compressors - Wikipedia
Surge in compressors - Wikipedia

Compressor ,surge, is a form of aerodynamic instability in axial compressors or centrifugal compressors. The term describes violent air flow oscillating in the axial direction of a compressor, which indicates the axial component of fluid velocity varies periodically and may even become negative. In early literature, the phenomenon of compressor ,surge, was identified by audible thumping and honking at frequencies as …

Anti-Surge Valve Piping for Gas Compressor - Piping ...

The ,anti-surge, line shall be connected immediately upstream of the check valve and the ,anti-surge, valve shall be located at minimum distance from the discharge line. The performance of the ,surge, control system is greatly dependent on the piping volume downstream of the compressor and upstream of the check valve, discharge shutdown valve and ,anti-surge, valve being minimum.
