We're going to change it up a little this post with a guest blogger, Mr. Harry Cheddie, P.Eng. CRE, CQE, CFSE; an industry-recognized expert in industrial safety.
Read MoreHas it been +two weeks already? In our last post - TMC PID basics - we reviewed some basic controls vocabulary associated with "PID control," and then summarized the PID forms (Parallel, Interactive, [...]
Read MoreIt's not an overstatement to say that there has been "a lot" of literature written about industrial process control and the venerable PID control algorithm. However, if there's been a lot written [...]
Read MoreSurge Detection - Eleven Frequently Asked Questions
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 MoreRefrigeration Systems - Quench Control (Part 2)
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 [...]
Read MoreIn 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 MoreRecycle Valve Sizing for Refrigeration Compressors
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 MoreProperly 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 [...]
