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 ...
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 ...
Baseline Report for the Fort Hood Army Base: Sept. 1, 2002 - Aug. 31, 2003
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M University, 2003)
This report presents electricity, natural gas and cooling baselines for the thermal plant, buildings located in the 87000 block, III Corp building and other buildings that were determined to be part of the ESPC project at ...
Witness Testing Of API 610 Centrifugal Pumps And API 611 Steam Turbines
(Turbomachinery Laboratory, Texas A&M University, 2012)
The tutorial outlines the basic concepts and offers some tips on witness testing of API 610 centrifugal pumps and API 611 steam turbines. The section on API 610 pump testing discusses performance, NPSH and mechanical run ...
