API 617 Anti-Surge Control
Understand surge phenomena, anti-surge control strategies, and control line positioning
Surge margin is the percentage difference between the operating flow and the surge flow, indicating how close the compressor is to its minimum stable flow limit.
It calculates surge margin, control line positioning, and minimum stable flow requirements per API 617 anti-surge control guidelines.
Surge causes flow reversal and mechanical damage. Anti-surge control ensures the compressor operates above its minimum stable flow per API 617 guidelines.
