  • Surge recurrence prevention control system for dynamic compressors
    Patent number: 5709526
    Abstract: A control system prevents recurrence of surge in a dynamic compressor. An anti-surge valve bypasses flow and is operated by the control system between a low limit and a full open position. The low limit is initially established to be zero, or a fully closed anti-surge valve. In the event of a compressor surge, the system detects a position of the anti-surge valve at the onset of surge, and stores a position related to the detected position as a new low limit. The stored position is preferably the detected position plus a small increment in order to prevent recurrence of the surge event.
