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 […]

Centrifugal and axial compressors are at the heart of many production processes. Effective compressor automation and turbomachinery control not only impacts efficiency, but also safety, reliability, production throughput and energy usage. A complete turbomachinery control system consists of measurement devices, high speed controllers, control valves, guide vane drives, turbine governors and more. I spoke with […]

Compressors are important assets for most process manufacturers and producers. Common threats to their health include high vibration, fluctuations in gas flow, surge conditions, suction or discharge restrictions, temperature spikes, seal failures and inadequate lubrication. In this 3:50 YouTube video, Video Tutorial for Emerson’s Essential Asset Monitoring Software – Compressor Monitoring Module, Emerson’s Jordan Rogers […]

Compressor surge control, or better stated, anti-surge control, is always a popular subject here on the blog. Posts written years ago still remain highly viewed. Preventing surge is critical for centrifugal and axial compressors. Wikipedia defines it: Axi-symmetric stall, more commonly known as compressor surge; or pressure surge, is a complete breakdown in compression resulting […]

Some of our most consistently popular posts here at Emerson Process Experts center on anti-surge control for centrifugal compressors. I had the opportunity to catch up with Emerson’s Ashish Patki when he was in town last month. Ashish shared a story where a national oil company was setting up an oil & gas processing facility […]
