TANDEM DRY GAS SEALS – Design and Maintenance Considerations for Enhanced Reliability and Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Dry Gas Seals have been in existence in the process centrifugal compressor industry for the last three decades and majority of the compressor units in operation today are installed with Dry Gas Seals. DGS sealing and the ...
Subsynchronous Shaft Vibration in an Integrally Geared Expander-Compressor due to Vortex Flow in an Expander
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Subsynchronous shaft vibration was observed in an integrally
geared expander-compressor when the machine was operated
with a partial load in the course of plant start up. The root
cause of the synchronous shaft vibration ...
Operator / OEM Collaboration on Trip & Alarm Rationalization
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Turbomachinery has increased in complexity and monitoring capabilities
over the last several decades. This has resulted in an increased number of
trips to protect various machinery systems. The prevailing OEM philosophy
has ...
Pump Cavitation – Physics, Prediction, Control, Troubleshooting
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This short course gives insight into roto-dynamic pump cavitation and provides
deeper understanding of particulars like cavitation inception, three-percent head
drop, 40,000 hours life criterion, cavitation damage potential, ...
Centrifugal Compressors 101: Part 1
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Reciprocating and centrifugal compressor similarities/ differences
-How do they work? (Potential Energy, Kinetic Energy, PE, KE, …)
-History of compressors
– Timeline, major advances
– Configurations, straight-through, ...
Gas Turbine Performance and Maintenance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this tutorial, we will address the basic characteristics of
each of the components in a gas turbine (compressor,
combustor, gas generator turbine, power turbine) and the
impact of typical control limits and control ...
HF Acid Alkylation Processes: Pump and Mechanical Seal Application and Design Considerations for Increased Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Hydrofluoric (HF) acid is an extremely corrosive solution commonly found in many oil refineries where it is used as a catalyst in the production of high octane gasoline blending stock. HF acid is almost synonymous with the ...
Examination of Methods of Dry Gas Seal Supply, Regulation, and Monitoring
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Compressor Dry Gas Seal Failure is a common issue that affects Turbomachinery train availability. Since most
turbomachinery trains are un-spared critical assets, unscheduled shutdowns have a major impact to the operating ...
Erosion Prediction of Gas Turbine Compressor Blades Subjected to Water Washing Process
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Blade fouling is a relevant problem in turbomachinery applications.
It affects both compressors and turbines. In the first
case, fouling can be generated by the presence of dust, ashes or
brackish air (in offshore ...
Drivetrain Protection Through Coupling Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper is designed to explain types of coupling advanced features and modifications used in turbomachinery, where drivetrain protection is desired. The subject includes a review of flexible coupling types, their ...
