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 […]

Any process manufacturer that has centrifugal compressors knows about a condition known as surge. Emerson’s Pete Sharpe described it to me: Surge is a condition that occurs on compressors when the amount of gas they are trying to compress is insufficient for the speed of the compressor and the turbine blades lose their forward thrust, […]

Before the holidays, ModelingAndControl.comControl Talk blog’s Greg McMillan had another set of eBooks, Centrifugal and Axial Compressor Control Student Text and Instructor’s Guide. These books were originally published in 1983 and the copyrights were returned to Greg. As described in the “About the Book” section, the text is geared for instrumentation and process control design […]
