Methods to Determine and Specify Rotodynamic Pump Dynamic Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Vibration caused by resonance is an industry problem for new and retrofit applications that persists due to lack of specification and upfront analysis. To limit the chances of resonant vibration, dynamic analysis of the ...
Commissioning A New Multiphase Pump Visualization Test Rig To Investigate The Internal Flow Field And Its Connection With Pump Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Pumps with helico-axial impellers are used to boost mixtures of gas and liquid, for instance in subsea production of unprocessed oil and gas. Experimental data is essential to fully understand and characterize the internal ...
An Alternative Option to Provide Seal Gas for Dry Gas Seals Which was Used During the First Start Up of Pipeline Booster Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This case study covers the initial start up (“black� start up) of a centrifugal compressor at a pipeline station located in a remote desert environment in Saudi Arabia, focusing on the issue that the suction and discharge ...
A Novel Approach to Installation of New Crude Bottoms Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Metallurgy upgrades for high TAN crudes and existing NPSH problems required the installation of two (2) new Atmospheric Towers and two (2) new Vacuum Tower Bottoms Pumps. • The new pumps are 450 HP and 1800 rpm versus ...
Integrally Geared Compressor Failure due to excessive pipe strain
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Following a complete overhaul of an integrally geared compressor, the compressor failed upon startup. The compressor ran for 7 seconds before the machinery protection system tripped the machine. During disassembly, it was ...
Prediction Of Lateral Vibration Behavior Of Integrally Geared Centrifugal Compressor During Synchronous Motor Startup By Transient Torsional-Lateral Coupled Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Startup transients of both torsional and lateral vibration behaviors of an integrally geared centrifugal compressor driven by a synchronous motor are examined by transient torsional-lateral coupled analyses, and the numerical ...
Fast and Ultimate Vibration Field Solution: From Problem Detection to Field Performance Validation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Predictive Merit of Computational Fluid Dynamics in Determining Marginal NPSH of Hydrocarbon Centrifugal Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
At inlet, sufficient pressure and NPSH margin is crucial for centrifugal pumpoperation. In cold and light hydrocarbon services; such as Liquefied Natural Gas,vapor pressure variations that is dependent on the temperature ...
Compression Turbomachinery For The Decarbonizing World
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
In the context of carbon reduction efforts, discussions evolve around hydrogen compression, as well as compression requirements related to CO2 capture, transportation and sequestration. In this paper, compression requirements ...
Predicting And Correcting Nonlinear Vibration Growth In Tilting Pad Journal Bearings Undergoing Large-Amplitude Whirl
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
When machines equipped with tilting pad bearings are well enough balanced to limit the journal whirl amplitudes to less than 40% to 50% of the bearing clearance, the bearing behavior can usually be considered linear and ...
