Maintenance & Reliability
Mitigate fouling in crude unit overhead—Part 1
In a refinery crude distillation column, up to 40% of the total heat removal may be found in the tower overhead condenser. The quantity of duty available makes heat integration (HI) between the column..
Novel use of sulfiding agent prevents refinery shutdown
When an insufficient supply of acid gas threatened to shut down operations at a US refinery, quick thinking, along with the novel use of a sulfiding agent and a strong supply chain made all the difference.
HP Reliability: Leaders must allocate time for technology updates
Just as a good medical doctor is expected to have wide knowledge on modern treatment options, we would expect reliability professionals to be equally informed on technology advances. There are numerou..

Noncorrosive bearings have high load capacityEDT Corp. has added Type E Solution bearings (Fig. 1) to its Solution line of severe service bearings. Type E Solution bearings have high load capacity and..
Optimize your compressor maintenance program
One deviation alone might not be enough to bring on a compressor failure, but, when several more deviations combine, the failure risk is known to increase exponentially.
Case history: Failure analysis of a syngas compressor
A first-stage impeller in a synthetic gas compressor failed after 20 years of service. The compressor is a six-stage centrifugal compressor driven by a steam turbine. This case history discusses the i..
Improve pressure drop calculations for saturated water lines
When saturated water flows through pipes and components, it flashes—thus increasing its specific volume and limiting the fluid flowrate. Due to these conditions, the calculation and design for pi..
World’s largest GTL facility turns to LIMS for enhanced operations
Pearl GTL is using a new laboratory information management system (LIMS) to manage, analyze and integrate data that keeps the plant functioning securely and efficiently.
HP Reliability: Four-stage, low-flow process centrifugal compressor can fill important industry gaps
In the 1970s and 1980s, multistage centrifugal compressors in the 3,000 acfm (about 5,000m3/hr) and lower flow ranges were largely confined to instrument and plant air duties. Three stages with interc..
HP Engineering Case Histories: Case 74: How to determine impact forces when troubleshooting
When troubleshooting failures, it is not unusual for the metallurgical report to indicate that the failure was the result of an impact type of force. The investigator who receives this information mus..
