Shop Rotordynamic Testing - Options, Objectives, Benefits and Practices
(Texas A&M University. Turbomachinery Laboratories, 2013)
Understanding the lateral rotordynamic behavior is critical in determining the reliability/operability of rotating equipment. Whether examining a centrifugal pump or compressor, steam or gas turbine, motor or generator, ...
CO2 Corrosion on Natural Gas Compressors: Criteria and Guidelines
(Texas A&M University. Turbomachinery Laboratories, 2013)
Liquid water and CO2 can easily lead to carbon steel corrosion, especially at high pressures. Corrosion can happen either during normal running or during pressurized standstill conditions. The present paper describes three ...
Electric Driven Centrifugal Compressor - Super Synchronous Vibrations of the High Speed Shaft Line: Observations, Assessment and Resolution
(Texas A&M University. Turbomachinery Laboratories, 2013)
An unacceptable vibratory behavior was encountered in 2012 during the full load string test of an electric driven centrifugal compressor. The vibrations were observed on the high speed part of the shaft line and both ...
Investigation Results for Surge Phenomena of Centrifugal Compressor Related with Piping Arrangements and Test Conditions
(Texas A&M University. Turbomachinery Laboratories, 2013)
The shop performance test of a hydrogen recycle gas compressor for refinery plant was conducted with the suction pressure of 50barA based on ASME PTC-10 Type-2 test. During testing, a surge phenomenon was observed at a ...

(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 1999)
This is the Spring 1999 progress report on ASHRAE Research Project RP 1004: Determining Long-Term Performance of Cool Storage Systems from Short-Term Tests. This report presents an update concerning the work that has been ...
Reduce Building Energy Consumption by Improving the Supply Air Temperature Schedule and Recommissioning the Terminal Boxes, Submitted to the Energy Management and Operations Division at the M.D. Anderson Cancer Center
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1995)
At the request of the Energy Management and Operations Department at M.D. Anderson Cancer Center, the Energy Systems Laboratory of Texas A&M University performed a study of optimizing the HVAC operation at its Basic Research ...
Report of Energy Efficiency Study and Metering/Utilities Profile for Electric Deregulation at Tarleton State University (TSU), Stephenville, Texas
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 1999)
The director of Energy Management & Controls and staff at Tarleton State University (TSU) do a very good job of maintaining TSU and keeping expenses down. They have metering installed in many buildings and track the campus ...
A Probabilistic Approach for Compressor Sizing and Plant Design
(Texas A&M University. Turbomachinery Laboratories, 2013)
Equipment sizing decisions in the Oil and Gas Industry often have to be made based on incomplete data. Often, the exact process conditions are based on numerous assumptions about well performance, market conditions, ...
Comparison Of Different Variable Speed Compression Train Configurations With Respect To Rotordynamic Stability And Torsional Integrity
(Texas A&M University. Turbomachinery Laboratories, 2012)
Wherever a variable speed gas compression train is needed for Oil & Gas upstream applications as well as for gas storage applications the primary decision has to be made between a gas turbine driver and an electric motor ...
Improving Reliability On A Centrifugal Compressor Experiencing Frequent Bearing Failures
(Texas A&M University. Turbomachinery Laboratories, 2012)
A 1957 vintage multi-stage centrifugal compressor, critical in a refrigeration process, had a history of poor reliability and LP stage bearing failures. Around 1995 the HP casing had been replaced and upgraded. In early ...
