Low Frequency Instability In A Process Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2004)
A catalytic gas process compressor experienced low frequency vibrations in excess of trip levels following installation of a honeycomb balance piston. After 12 years of operation, low seal oil differential forced an unplanned ...
High Pressure H2 Recycle Compressor Dry Gas Seals Retrofit
(Texas A&M University. Turbomachinery Laboratories, 2004)
Dry gas seal conversions over the last 20 years have progressively become a standard upgrade solution to improving reliability, efficiency, safety and environmental issues related to oil seal technology. The application ...
A Simple Alternative to Keyed Hubs - No More Torches
(Texas A&M University. Turbomachinery Laboratories, 2004)
Application And Operating History Of Moderate-Speed API 618 Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2004)
API Standard 618 (1995), “Reciprocating Compressors for Petroleum, Chemical, and Gas Industry Services,” is written to cover both moderate-speed and low-speed reciprocating compressors for critical service applications but ...
Process Output Improved through Online Monitoring of Hydrogen Reciprocating Compressor
(Texas A&M University. Turbomachinery Laboratories, 2004)
Gas Turbine Axial Compressor Fouling And Washing.
(Texas A&M University. Turbomachinery Laboratories, 2004)
The privatization of utilities, intense competition in the petrochemical and gas distribution industries, coupled with increasing fuel costs, have created a strong incentive for gas turbine operators to minimize and control ...
Rotating Component Modal Analysis And Resonance Avoidance Recommendations.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Rotating blade and disk fatigue failures cause a fairly small percentage of machine shutdowns, but can require extensive repairs and downtime. This tutorial focuses on steam turbines, centrifugal compressors, and axial ...
Resolving A Resonant Fatigue Problem On A Large Radial Inflow Expander.
(Texas A&M University. Turbomachinery Laboratories, 2004)
A series of failures of radial inflow hot gas expander driving a centrifugal compressor in a nitric acid plant plagued the second author’s former company over a 24 year period. The 19,000 hp single-stage radial inflow ...
Mechanical Behavior of a 9.7 MW Induction Motor Under Fault Conditions – A Case History
(Texas A&M University. Turbomachinery Laboratories, 2004)
