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.Read More
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 [...]Read More
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 [...]Read More
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 [...]Read More
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 [...]Read More
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 [...]Read More
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 [...]Read More
