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..
HP Brief
Train accident raises concerns on safetyThe train derailment that killed at least 38 people in Lac-Mégantic, Quebec, has heightened safety concerns about crude oil shipments by rail. It has been ..
HP Impact: Dilbit poses no extra pipeline risk
Diluted bitumen (dilbit) has no greater likelihood of accidental pipeline release than other crude oils, says a new report from the National Research Council. The report found that diluted bitumen has..
Optimize amine units and improve refinery profitability
The alkanolamine system in a refinery, better known as the amine unit, is used to remove hydrogen sulfide (H2S), carbon dioxide (CO2) and mercaptans (collectively referred to as acid gases) from proce..
