Upgrading Centrifugal Compressors With Polymer Seals In An Ethylene Plant - A Case History.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Thermoplastic use a labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal ...
Gas Turbine Performance - What Makes The Map?
(Texas A&M University. Turbomachinery Laboratories, 2000)
The power and efficiency characteristics of a gas turbine are the result of a complex interaction of different turbomachines and a combustion system. This tutorial addresses the basic characteristics of each of the components, ...
Critical Review Of Compressor Impeller Vibration Parameters For Failure Prevention.
(Texas A&M University. Turbomachinery Laboratories, 2000)
One of the most difficult diagnostic problems for centrifugal compressors is fatigue failure of an impeller, especially those with covers. The structure of a covered impeller is inherently resistant to alternating forces ...
Multiple Resonance Vibration Mitigation On A 54,000 HP Parallel Shaft Double Helical Speed Increaser.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Test stand vibration measurements on a partially loaded 54,000 hp, parallel shaft, double helical speed increaser revealed synchronous resonant vibrations near normal operating speed. Further testing confirmed the lateral ...
Turbomachinery Vision - 2000 (Getting the Most out of What You Got).
(Texas A&M University. Turbomachinery Laboratories, 2000)
The Historical Evolution Of Turbomachinery.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper presents a comprehensive treatise of the antecedents, evolution, developments, and inventions relating to turbomachinery from early paddle wheels to modern turbojets emphasizing the constant challenge, failures, ...
Low Emissions Combustion Technology For Stationary Gas Turbines Engines.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The need to control exhaust emissions from stationary power sources is dictated by environmental regulations that limit the amount of smoke (particulates), sulfur dioxide, carbon monoxide, hydrocarbons, and oxides of ...
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 ...
