Case history: Failure analysis of a syngas compressor

SABIC Technology Centre: van Zyl, G.  |  Al-Zahrani, E.  |  Al-Meshari, A.  |  Al-Haroon, M.

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

Hydrocarbon Processing Staff: Bloch, Heinz P.

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

Consulting Engineer: Sofronas, A.

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.
