Compressors
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.
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..
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..
Chevron expands North American compressor oils
Chevron said that Cetus PAO and the rebranded Cetus HiPerSYN (formerly HiPerSYN) have joined Cetus DE to create a family of premium compressor oils formulated for use in a wide range of applications, including portable and stationary rotary screw, rotary vane, and reciprocating compressors.
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..
HP Engineering Case Histories: Case 73: Useful troubleshooting tools to keep at hand
Over the past 45 years, the author has pursued troubleshooting machinery and pressure vessels. It has also been the subject of this column. The troubleshooting tools used in this endeavor have been an..
