Reciprocating Compressor Motor Vibration During Initial Start-up
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Shortly after start-up of a new 4 throw 3 stage reciprocating compressor, high motor vibration was recorded on a machinery monitoring system. The single bearing motor vibration levels reached 260 microns (10.25 mils) during ...
Annular Clearance Gas Seals In The 21st Century: A REVIEW OF THE EXPERIMENTAL RECORD ON LEAKAGE AND DYNAMIC FORCE COEFFICIENTS, INCLUDING COMPARISONS OF MODEL PREDICTIONS TO TEST DATA
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...
Centrifugal Compressor Configuration, Selection And Arrangement: A User's Perspective
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The detailed sizing and selection of centrifugal compressors may be somewhat of a mystery to the typical user. Once the suction and discharge process conditions and required flow rates are established, they are submitted ...
Materials And Coatings For Turbomachinery In Hydrogen Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Centrifugal compressors are commonly utilized for hydrogen compression in refineries for critical applications, and a potential “Hydrogen Economy� to lowering the carbon footprint on a worldwide scale will require ...
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 IMPROVED THRUST PREDICTION MODEL FOR HIGH PRESSURE MULTI-STAGE CENTRIFUGAL COMPRESSORS
(2022)
Axial thrust load predictions are an important aspect when it comes to predicting the performance of centrifugal compressors. The accurate prediction of axial thrust forces is necessary to size the appropriate balance ...
Case Study on Additive Manufacturing Metallic and Non-Metallic Pump Impellers for Corrosive Application
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2024-02-27)
At one of our customer/end-user chemical plants in Singapore, they had a problem with frequent replacement of the Hastelloy C impellars casted used in their centrifugal pumps in service with Sodium Hypochlorite application. ...
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 ...
