Some of the most perennially popular posts (say that fast 10 times!) here on the blog involve axial or centrifugal compressor surge control, or better stated—anti-surge control. In a paper presented at this year’s AIChE Spring Meeting, Emerson’s Greg McMillan—a member of the Process Automation Hall of Fame—presented Compressor Surge Modeling and Control. In his […]
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 […]
Authors: Rossella Mimmi and Dave Seiler Petroleum commodity releases can have serious consequences, so ensuring pipeline integrity is crucial for operators. Pipeline integrity is not just about preventing incidents, but is a holistic approach to the prevention, detection, and mitigation of these undesired commodity release such as surge. In this two-part series, we will provide […]
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 […]
