VSDS Motor Inverter Design Concept For Compressor Trains Avoiding Interharmonics In Operating Speed Range
(Texas A&M University. Turbomachinery Laboratories, 2012)
During operation of compressor trains by a variable speed drive system (VSDS), integer and non-integer harmonic currents are generated in the inverter. Via the electrical system of the inverter and the motor, an excitation ...
Babbitted Bearing Health Assessment
(Texas A&M University. Turbomachinery Laboratories, 2012)
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 ...

CO2 Compression At World's Largest Carbon Dioxide Injection Project
(Texas A&M University. Turbomachinery Laboratories, 2012)
Compressors for carbon dioxide (CO2) applications have been widely used in the O&G industry for urea production, enhanced oil recovery (EOR) and CO2 pipeline services for many years. New environmental challenges have ...
Hydrate Occurrence in Centrifugal Compressor Systems
(Texas A&M University. Turbomachinery Laboratories, 2012)
Gas Seal Contamination
(Texas A&M University. Turbomachinery Laboratories, 2012)
Design of seals and sealing systems requires multidisciplinary skills and deep understanding of interactions between the seals and its environment. This paper proposes to present typical gas seals contaminants and corresponding ...
Effectiveness of Windage Features on High Speed Couplings
(Texas A&M University. Turbomachinery Laboratories, 2012)
Following the changes to API 671, there is a requirement to reduce temperature around guarded coupling designs. Existing features used in high performance (HP) couplings involve various methods of shrouding and covering ...
