TT06 - Revamp/Re-rate Design Considerations
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This tutorial paper describes the mechanical and aerodynamic factors that must be considered when revamping, re-rating or upgrading a centrifugal compressor. The possible motivations for choosing to revamp existing ...
TT07 - Methods to Effectively Evaluate Modern Journal Bearing Performance and Achieve High Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Centrifugal compressor and steam turbines commonly use hydrodynamic journal bearings. These bearings can be fixed sleeve or tilting pad type. Most end users expect bearings to trouble free from major turnaround to major ...
TT08 - Motor/Generator Set Non-Contacting Torsional Vibration Measurements
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
Owners of variable frequency drive (VFD) trains report challenges in detecting and monitoring shaft stress resulting from drive harmonics and inter harmonic distortion interactions with shaft torsional natural frequencies ...
TT03 - Computing the Safety Integrity Level (SIL) for Turbo Machinery Protection
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
SIL has become the new standard by which industry, manufacturers, and end users will be held to by regulators as good engineering practice. Specifically supporting turbomachinery, the API670 Machinery Protective Systems ...
TT09 - A Comparison of Operating Deflection Shape and Motion Amplification Video Techniques for Vibration Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
An introduction to the technology used in Motion Amplification Video (MAV) for vibration analysis of structures and machinery. The MAV technique is compared to the venerable Operating Deflection Shape (ODS) tool that has ...
TT05 - Dry Gas Seal Failure Simulation Methodology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The failure of dry gas seals is a critical event in Oil & Gas industry that if not correctly managed can lead to uncontrolled gas release to atmosphere. It is important to properly estimate the potential risks due to the ...
CSP12 - Post-Event Analysis of Subsea Electrical Submersible Pumps Using Electrical Waveform Monitoring (EWM)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
TBD
CSP10 - Extending MTBF of Seals in Boiler Feed Water Service
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The customer experienced short seal life on a set of multi-stage, double ended pumps that were commissioned in 2009. A single seal design with piping plan 23 system was used with pump cooling jackets. The average seal life ...
Landsat assessment of estuarine water quality with specific reference to coastal land-use
(1978)
The highly productive and economically valuable estuaries of the United States are under environmental stress. The effects of human beings in most cases will inevitably increase turbidity, siltation and related pollution ...
TT12 - Turbomachinery for Refinery Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This tutorial covers the basics, applications, and operation of compressors, expanders, steam turbines, and gas turbines in refinery applications. Modern refineries utilize a wide range of turbomachinery that must flexibly ...
