HP Engineering Case Histories: Case 75: Analyzing wear when troubleshooting
Wear occurs frequently on machinery. In its simplest terms, it is the undesirable removal of material. When troubleshooting the root cause of wear in equipment, the engineer’s interest should be ..
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..
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.
Digital is the solution for modern compressor protection
Compared to traditional analog communications technologies, digital systems cost less, offer greater flexibility, and are more reliable thanks to built-in self-checking systems and resistance to interference.
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 Reliability: Expect adversity, but plan for success
Consider that a major oil refinery was planning a substantial modernization project in 2008. Energy efficiency gains and the ability to process a more readily available crude slate were key motivating..
Rerating rotating equipment optimizes olefins plant performance
Rerating your installed compressors and steam turbines can become a cost-effective, time-saving solution for increasing throughput without having to invest in new equipment.
Investigate power limitations in a large steam turbine
An investigation was carried out to rectify power limitations for a steam-turbine driver of a cracked-gas compressor (CGC) in a world-class ethylene plant.DescriptionThe turbine is a nine-stage, impul..
Seal safety may require going beyond typical standards
Top industry professionals believe users must reach beyond typical standards in applying safer mechanical seals when hazardous and toxic chemicals are involved.
