Recent Technologies For The Reliability And Performance Of Mechanical-Drive Steam Turbines In Ethylene Plants.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Recently, large capacity ethylene plants have been constructed in the world and the trend for the capacity of these plants is increasing. At present it reaches up to about one million tons per year and more. Accordingly, ...
Designing High Performance Steam Turbines With Rotordynamics As A Prime Consideration.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Steam turbines first produced useful work well over a century ago. Their reliability, efficiency, and versatility are possibly the three man attributes that have contributed to their widespread utilization in a wide range ...
API Centrifugal Compressor Oil Seals And Support Systems - Types, Selection, And Field Troubleshooting.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Even though dry gas seals for centrifugal compressors are becoming more popular, knowledge and understanding of oil seals and their associated support systems are still very important. Many existing compressors still have ...
Integrally Geared SPI 617 Process Gas Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Integrally geared (IG) centrifugal compressors, originally developed for plant and instrument air service, continue to gain acceptance in process gas applications as an alternative to other types of centrifugals, and in ...
Design Considerations For A 66,000 HP Motor Driving An Air Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The design of a 66,000 hp electric motor to drive an air compressor presented significant design challenges. Using conventional assumptions in assessing the bearing support and foundation stiffness yielded a scenario where ...
Review Of API Versus AGMA Gear Standards - Rating, Data Sheet Completion, And Gear Selection Guidelines.
(Texas A&M University. Turbomachinery Laboratories, 2000)
There are many gear tooth and gearbox rating standards existing in the world. For a given gearbox, the rating system that is used can give very different answers in the amount of power that can be transmitted. If a user ...
Influence Of Previous Operational Cycle On The Microstructure Of Rejuvenated Ni-Base Superalloy Gas Turbine Blades After Their Return To Service.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The practice of rejuvenating reheat treatments, with and without hot isostatic pressing (HIP), has been successful in restoring severely overaged gas turbine blade microstructure and alloy properties to a nearly “as-new” ...
Evaluation Of A High Speed, Light Load Phenomenon In Tilting-Pad Thrust Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper discusses a newly found high speed, light load hydrodynamic tilting-pad thrust bearing phenomenon was first witnessed on centrifugal compressors operating above 10,000 rpm. Testing results have shown that in ...
A Review Of Aerodynamically Induced Forces Acting On Centrifugal Compressors, And Resulting Vibration Characteristics Of Rotors.
(Texas A&M University. Turbomachinery Laboratories, 2000)
There are several sources of nonsynchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, diffuser ...
Design, Testing, And Field Experience Of A High-Pressure Natural Gas Reinjection Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper explains the design and testing of a high-pressure centrifugal compressor. It also covers commissioning and field experience. Importance issues for high-pressure compressors are highlighted in the paper in general ...
