(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Sometimes when tasked with an effort that has been done many times before, the same path is followed over an over again. Sometimes the saying “Just because we have always done it that way, doesn’t mean it’s right” is very ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)A bolted raised face Joint (with O-ring gasket) was failure prone. An axisymmetric FEA (finite element analysis) of the Joint verified why: the flanges were not stiff enough (not thick enough); too much flange rotation ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)A method has been developed that allows reasonably accurate sectional performance evaluation of sideload compressors based upon only external measurements available from the streams entering and exiting the compressor ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)The purpose of this work is to present the first results of a practical approach developed for measuring the performance on energy and carbon of turbomachinery installed at offshore oil production plants, based on the ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)The primary purpose of performing a lateral rotordynamic analysis for centrifugal compressors, steam turbines and other rotating machines is to ensure that there are no undesirable rotor/bearing performance issues that ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)There are several sources of non-synchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This paper describes efforts undertaken to increase the use of non-metallic components in research and development as well as component/stage validation testing. The switch to non-metallic or polymer components was driven ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)During commissioning of an open-casing test rig, a loud (above 105 dB) high pitch “squealing” sound occurred at speeds above 3,000 rpm. All elements of the rig were removed except the bearings yet the noise persisted. ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The paper describes the link between additive manufacturing techniques and topological optimization design process. An overview of Inconel718 printed material characteristics and as printed quality is given Finally ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Two-thirds of the pipelines in North America are transporting non-crude hydrocarbon products such as NGL, diesel, avaiation fuel, Copyright© 2020 by Turbomachinery Laboratory, Texas A&M Engineering Experiment Station ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Three years ago, the Non-Pushing Secondary Seal (NPSS) technology was introduced to the pipeline industry and since then it has successfully addressed challenging pipeline services. Over 300 seals have been installed ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Suggested Topics: Meeting current rotordynamics stability standards CO2 Compressors High flow coefficient/Mach number impellers Coupling and alignment impacts on asymmetric rotordynamics Sour gas/Chloride implications ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)A large aero-derivative gas turbine in electrical generation service was exhibiting high vibration at the LP compressor section (1.5 in/s peak) at low load operation. Thorough testing, using Experimental Modal Analysis ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This case study covers the aerodynamic design of a centrifugal compressor that replaced an aging compressor experiencing leakage issues. The replacement compressor was required to reuse the existing rotor, bearings, seals, ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)As speed and power density increase, validation of analytical prediction with actual test data plays an important role to ensure avoidance of critical speeds in high-speed turbomachinery and a reliable design. For a typical ...
