Rod Drop Monitoring, Does It Really Work?.
(Texas A&M University. Turbomachinery Laboratories, 2000)
In 1994, the Twenty-Third Turbomachinery Symposium featured the first session of Discussion Group 12, “Reciprocating Compressors.” Each year since its inception, there has been one consistent discussion topic brought up ...
Torsional Vibration Analysis Of Synchronous Motor-Driven Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 2000)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral rotordynamics problems, torsional failures are especially heinous since the first symptom of a problem ...
FCC Hot Gas Expander Reliability Upgrade Evaluation.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The hot gas expander (PRT) is an integral part of the refinery’s fluid cat cracker unit’s PRT train. Since 1995, the PRT has experienced four unplanned outages due to blade and steam baffle bolting failures. These failures ...
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” ...
