    Blog: Selection Criteria in Compressor Anti-Surge Valves

    Some of the most consistently popular posts here on the blog involve compressor anti-surge control. It’s a condition in centrifugal and axial compressors where a flow reversal condition can occur. Wikipedia defines centrifugal compressor surge as: …the point at which the compressor cannot add enough energy to overcome the system resistance or backpressure. [26] This causes a rapid flow reversal (i.e., surge...
