DEVELOPMENT AND DESIGN OF ANTISURGE AND PERFORMANCE CONTROL SYSTEMS FOR CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The development and design of control systems for centrifugal and axial compressors is discussed and explanations given to bring together features of control systems on varying machine designs. Potential problems resulting ...
THE CHALLENGE FOR THE ACCURATE DETERMINATION OF THE AXIAL ROTOR THRUST IN CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The axial thrust is basically generated by a pressure imbalance across the impeller. The impeller is subjected to a great force trying to move it against the incoming flow. The cumulative thrust of all impellers on the ...
BABBITTED BEARING HEALTH ASSESSMENT
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Within most plants there is often a desire to extend the time between outages. Several factors determine this but one to consider is the bearings ability to run for the extended time.
This Tutorial will address common ...
TUTORIAL: TRANSIENT MODELING AND ANALYSIS OF CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Centrifugal compressors are subject to transient events, such as emergency shutdowns, which can cause energetic surge events during rapid shutdown transients. Many modeling tools are used to predict the behavior of compressor ...
END USER’S APPROACH TO CALCULATING COMPRESSOR PERFORMANCE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Oil and Gas industry end users have generally approached the topic of centrifugal compressor performance estimation with little consideration to the effect of process gas conditions. This is customary since end users depend ...
Head-flange O-rings on Barrel Type Centrifugal Compressor Units at RasGas: Issues & Resolutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
RasGas is operating many centrifugal compressors from different major OEM’s. Of an OEM product-line, twenty-four (24) centrifugal compressors with a total rated power of roughly ~ 900 Mega-watt are in operation, out of ...

VSD Motor Intermittent Vibrations Excursions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Solving a Coupling Unbalance Problem in the Field
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
When a large (3.4 meters long) diaphragm coupling was suspected of causing excessive (120 microns p-p) 1X unbalance vibration between a 90+ Megawatt Gas Turbine and a Propane Compressor in an LNG plant, there was not time ...
