We've been getting a lot of surge detection questions lately - what follows are the eleven most frequent, surge-detection-related questions we've been asked.

In our last post, Refrigeration Systems - Quench Control (Part 1), we discussed the industrial refrigeration process, and basic recycle temperature control. In what follows, we will discuss the [...]

This will be the first of two posts discussing: 

Quench Control in hydrocarbon processing refrigeration systems.

In the hydrocarbon processing industry, refrigeration systems are widely used to [...]

In this post we will describe how we can convert a compressor manufacturer's compressor performance map to a surge line we can use to determine where, in relation to that surge line, a compressor is [...]

Proper selection of the recycle valves for a refrigeration compressor can be significantly more complicated than the selection valves for most other anti-surge applications. Refrigeration Compressors [...]

With the proliferation of dedicated digital anti-surge control systems over the last 20

Properly designed compressor controls should not only protect the compressor, they should protect the process.

Centrifugal compressors are common-place in many process plants due to their small [...]

What's Stonewall?

Stonewall occurs in a centrifugal compressor when the velocity of the gas in at least one stage reaches the speed of sound (Mach 1) at the gas conditions in that part of the [...]

Incipient surge is a flow disturbance in the impeller of a centrifugal compressor that occurs at low flows. However, calling this phenomenon “surge” is a bit of a misnomer. Since the disturbance [...]
