Application Of Dry Gas Seals On A High Pressur Hydrogen Recycle Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Maintenance and operation of high pressure seal oil systems on centrifugal compressors has been a major problem faced by refinery operators. This problem is intensified when sealing gases like hydrogen and mixtures of ...
Water Contamination Of Steam Turbine Lube Oils - How To Avoid It.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Ever since steam turbines have been built, contamination of the lube oil by water has been a persistent problem. Water contamination will result in rusting of ferrous components, accelerate sludging leading to sticking of ...
A New Computer Program For Pump Rotordynamic Analysis
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A new computer program for pump rotor analysis has been developed to improve the accuracy of critical speed, stability, and response calculations for multistaging centrifugal pumps. The program capabilities include: (1) ...
Solution Of Subsynchronous Vibration Problems In Radial Flow High-Speed Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Experience, theoretical and practical, investigations are presented on two radial flow high-speed turbines, which showed unacceptable high subsynchronous vibrations during operation onsite. The first example deals with a ...
Experience With Online Condition Monitoring System.
(Texas A&M University. Turbomachinery Laboratories, 1988)
A total online condition monitoring system has been in operation on the world's largest offshore facility located off the coast of Norway. The Ekofisk platforms are operated by the Phillips Petroleum Company Norway and ...
Turbine Protection System Performance.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The need to protect a turbine generator from abnormal operating condidtions is a given. Power plant operational historical data indicate that malfunction of the turbine protection system (TPS) has been the initiator of ...
Operating Experience With Improved Steam Turbine Packing Rings.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs ...
Large Motor Specification and Selection
(Texas A&M University. Turbomachinery Laboratories, 1988)
The induction motor has been the work horse of industry for many years. It has achieved this position by virtue of its ruggedness, and relative low cost. Induction motors include the popular squirrel cage and the versatile ...
Improving Plant Economy Through Retrofit And Maintenance Of Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Retrofits on compressors can become attractive if the operating requirements of a plant change. Often, compressor modifications are imposed by process changes due to market demands or new process technologies. Sometimes, ...
Turbine-Generator Life Assessment/Extension.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The approach and methodology to life assessment/extension are described. Items considered are nondestructive testing, material testing, flaw sizing, stress analysis, fracture mechanics analysis and cumulative damage analysis. ...
