Siemens to supply new compressor trains for three LNG plants in China
The compressor trains in the three plants each consists of a six-stage vertically-split compressor and a Siemens constant speed electric motor. This type of drive and control, using inlet guide vane assemblies, provides more efficient and reliable operation than conventional compressor solutions.
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.
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..

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 ..
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 Reliability: Gain more flexibility with special liners for reciprocating compressor cylinders
By changing only the crank-end head, piston and rod assembly, the same cylinder body can be mounted on any of the common 5-in. to 7-in. stroke compressor frames that have been manufactured in the last five decades.
