Mechanical Upgrades To Improve Centrifugal Compressor Operation And Reliability.
(Texas A&M University. Turbomachinery Laboratories, 2003)
In today’s business environment, centrifugal compressor reliability is more critical than ever. Unscheduled equipment downtime has a negative impact on plant operations, oftentimes resulting in a temporary halt of production. ...
Determining The Root Causes Of Subsynchronous Instability Problems In Two Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2003)
This paper discusses the rotordynamic instability problems experienced with two separate centrifugal compressors. While the root causes of the instabilities are very different, the analysis methodology of reconciling the ...
Desktop Use Of Computational Fluid Dynamics To Design And Troubleshoot Compressors And Turboexpanders.
(Texas A&M University. Turbomachinery Laboratories, 2003)
For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computation fluid dynamics) software and desktop computing power have ...
Solving Stability Problems While Commissioning A 100 MW Turbine Generator Set.
(Texas A&M University. Turbomachinery Laboratories, 2003)
A new cogeneration installation was in the process of being commissioned when severe subsynchronous vibration was detected on the generator during no load tests. Subsequently, two rotordynamics problems were discovered. ...

Tilting Pad Journal Bearings With Spray-Bar Blockers And By-Pass Cooling For High Speed, High Load Applications.
(Texas A&M University. Turbomachinery Laboratories, 2003)
With performance considerations driving the design of rotating equipment, operating speeds and journal loads have increased greatly in recent years, often exceeding generally accepted design limits. In order for tilting ...
Recycle Gas Compressor Designed For High Unbalance Tolerance And Stability.
(Texas A&M University. Turbomachinery Laboratories, 2003)
A process recycle gas compressor was needed that would be highly reliable and tolerant of suction contaminants of sticky material that is abrasive and corrosive. Squeeze film dampers, pinched diffusers, and other technologies ...
Evaluation Of Centrifugal Compressor Stability Margin And Investigation Of Antiswirl Mechanism.
(Texas A&M University. Turbomachinery Laboratories, 2003)
Stringent stability screening criteria by the American Petroleum Institute (API) result in higher level rotor stability analyses to be performed on more intermediate-pressure compressor rotors and in more detail. These ...
