Sub-Synchronous Vibration on Centrifugal Compressor with Tilt-Pad Bearings
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This presentation provides a success story that sub- synchronous vibration was eliminated on a centrifugal compressor. The sub-synchronous vibration originally occurred at high operational speed on this 5-stage hydrogen ...
Vibration Analysis for Turbomachinery
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Turbomachinery requires a higher level of vibration analysis than general purpose machinery. This includes identifying natural frequencies or modes of a system to determine if a potential resonance occurs. The complexity ...
Continuous Control of Lube Oil Water Contamination - Never get Surprised Again
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Problem: High water contamination of lube oil damaged a turbine driven process blower on multiple occasions. Traditional solution:• Monitor oil for milky appearance – only qualitative • Drain free water from reservoir, but ...
Resolving Cyclic Vibration on an Instrument Air Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Instrument Air Compressors are considered critical equipment in the plants, supplying compressed air to the instrumentations in the field. This case study focuses on cyclic vibration phenomena observed in the 2nd and 3rd ...
Adapting Hermetically Sealed Compressor Technology To Deal With Sour And Corrosive Gases
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The Oil & Gas industry faces increasing challenges to meet growing energy demands with the most sustainable exploration and production techniques. Compressor manufacturers have responded to these challenges with the ...
Performance Test Of A Liquid Tolerant Impeller And Validation Of Wet Compression Predictive Model
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Standard centrifugal compressors are designed to process gas with limited liquid content: significant presence of liquid may be responsible for the rapid erosion and corrosion of both static and rotating components that ...
Effect Of Relative Journal Bearing And Honeycomb Seal Direct Stiffness On Radial Synchronous Vibrations Of High-Pressure Centrifugal Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
High pressure compressors are commonly equipped with honeycomb seal on the balance piston, as an effective mean to improve the rotordynamic stability of the system. The gas leakage flow across the honeycomb seal clearance ...
Rotor Balancing Tutorial
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The purpose of this tutorial is to describe details related to shop and field balancing of turbomachinery. The target machinery is API type turbomachinery such as steam turbines, compressors, and other rotating machinery ...
Subsea Compression - Current Technology and its Use to Maximize Late Life Production
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Oil and gas production from offshore fields has been established since the second half of the last century. The continuous need and search for new fossil resources has driven the technology to adapt towards harsher and ...
Compressor Loadsharing Control And Surge Detection Techniques
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Centrifugal compressor trains operating in parallel or series arrangements are complex when it comes to turbomachinery control. Methodologies for controlling compressor trains in these arrangements piping layout considerations ...
