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 ...
