Maintenance & Reliability
Executive Viewpoint: Interconnected neural networks drive breakthrough optimization
We have all learned that technology alone will not improve our operations.
Engineering Case Histories: Case 111: Predict the cause of cracks in gear teeth and time to failure
In the practice of engineering, we sometimes wish for better hindsight or foresight.
Reliability: Finding upgraded sealing solutions
By universal agreement, the safety and reliability of facilities in the hydrocarbon processing industry—and most other industrial plants—are of highest importance.
High-frequency acoustic excitation—Part 2
Failure of a piping section at the outlet of pressure safety valves (PSVs) and control valves—where significant differential pressure exists (particularly in gas processing industries)—is a common problem in industries.
Down with downtime: Repair complex petrochemical components with selective electroplating
The volatile impact of the coronavirus pandemic hit at the same time the petrochemical industry was entering a downcycle.
Strategies to minimize piping thermal maintenance system cost without compromising performance
Where process fluid must be maintained within a certain operating temperature window, the piping will likely require the application of a thermal maintenance system.
Double-suction centrifugal compressor in ethylene plant inlet piping design
Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.
Optimizing failure data analysis
A critical objective of engineers who design an automatic protection system is to lower the false trip rate and to lower a key metric called average probability of failure on demand (PFDavg).
Specifying internals in sour water strippers—Part 2
Sour water stripping is a common process in petroleum refineries and other processes where hydrogen sulfide (H<sub>2</sub>S) is present.
Specifying internals in sour water strippers—Part 1
A sour water stripper (SWS) system is a common process in petroleum refineries and other processes where hydrogen sulfide is present.
