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...
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.
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...
In this 2:50 YouTube video, Optimized Anti Surge Control Simulator, Emerson’s Tom Bass and CCC’s Rick Fausel describe the Innovation Center simulator setup. The purpose is to show the control strategies working with the control valve to meet the application requirements for surge protection.
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...
Update: Greg has published a post, Checklist for Compressor Surge Control Tips which should give you some things to consider for your centrifugal and axial compressors. Orginal post: It's great to questions from automation professionals from some of my posts built up...
Recent YouTube video email notifications are letting me know that the Emerson Process Management divisions are using this visual medium to share unique capabilities in their products. I'll highlight three examples from the Micro Motion Coriolis flow and density...
