Development and Testing of a Supercritical CO2 Compressor Operating Near the Dome
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Supercritical Carbon Dioxide (sCO2) power cycles are a transformational technology for the energy industry, providing higher thermal efficiency compared to traditional heat-source energy conversion including conventional ...
Advanced Sealing Solutions for Non-Crude Hydrocarbon Services
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 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 ...
Pump Tut - WHY MACHINES FAIL TO FOLLOW TEXTBOOK STATED RULES, AS ILLUSTRATED BY SHAFT CRACK AND ROTOR SELF EXCITED VIBRATION CASES IN CRITICAL MACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial demonstrates some aspects of rotating machinery diagnostics where there is an apparent difference between the actual response of a machine and its expected behavior for a certain type of malfunction as typically ...
Overview of Grid-Scale Machinery-Based Energy Storage Technologies
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Grid-scale energy storage is needed to smooth variable renewable power sources and enable deep penetration of renewable power generators into the energy mix. There are many existing or developing machinery-based energy ...
Significant cost savings in Crude oil / Multiphase pump application by using Diamond seal Face material technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In an upstream facility in Venezuela, Single Mechanical Seals in combination with API 682 Piping Plan 32 and 62 have been used in a Multiphase twin-screw pump application successfully over many years. It was clients target ...
PNEUMATICALLY ACTUATED CONTROL VALVES IN OIL SYSTEMS: HARDWARE RECOMMENDATIONS AND TUNING CONSIDERATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Well designed and properly commissioned auxiliary systems are crucial to the reliability of rotating equipment. This paper addresses the upfront hardware selection and commissioning of pneumatically actuated control valves ...
Self excited torsional vibration in single shaft combined cycle turbine-generator train
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case history describes the investigation of the source of unstable behavior of a newly commissioned single-shaft, combined cycle, power generator unit. The source was found to be nonlinear operation of the flexible ...
How to detect Electrostatic discharge (ESD) using proximity probes on rotating machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In this session, a brief introduction about electrostatic discharge phenomena will be done. Then three historical cases with Electrostatic Discharge (ESD) issue will be analyzed in order to explain how to detect Electrostatic ...
A New Approach to Large Motor Driven Pump Trains
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 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 ...
MEASURED LEAKAGE AND ROTORDYNAMIC-COEFFICIENTS FOR THE FOLLOWING LIQUID ANNULAR SEALS: (A) SMOOTH-ROTOR/GROOVED-STATOR, AND (B) GROOVED-ROTOR/SMOOTH-STATOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Test results are presented and compared for the following annular pump seal geometries: (a) a smooth-rotor/circumferentially-grooved stator (SR/GS) and (b) a smooth-stator/circumferentially-grooved rotor (GR/SS). The GR/SS ...
