Transient Surge Measurements Of A Centrifugal Compressor Station During Emergency Shutdowns.
(Texas A&M University. Turbomachinery Laboratories, 2009)
For every centrifugal compressor installation, the design of the surge control system is vitally important to prevent damage of the compressor internal components, seals, and bearings. While most surge control systems are ...
Design And Experimental Evaluation Of A High-Speed, Directly-Coupled, Multi-Megawatt Permanent-Magnet Machine.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This paper reexamines some of the usual assumptions in deploying synchronous machines in multi-megawatt, high-speed application. The detailed design and experimental evaluation of a prototype high-speed, directly-coupled, ...
Using Finite Element Analysis (Fea) To Estimate Reed Frequency Of Vertical Motors For Pump Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Vertical motor/pump systems that run close to the motor reed frequency may experience significantly high vibration levels, which can damage the motor as well as the entire pump system. These damages can result in costly ...
Winter Vibration Problems on VS6 Booster Pumps and Solutions
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background: Three multistage canned vertically-suspended pumps are installed at Kerrobert, Canada to transfer crude oil. The pumps are driven by 1000 HP vertical motor at 885 RPM. Problem Statement: The installed pumps ...
World's First 10,000 PSI Sour Gas Injection Compressor
(Texas A&M University. Turbomachinery Laboratories, 2008)
This paper traces the development of the original sour gas injection (SGI) concept, the methodology used for managing risks, detailed design and testing of compression train components, compressor train shop string tests, ...
Torsional Vibration Problem with Motor/ID Fan System Due to PWM Variable Frequency Drive
(Texas A&M University. Turbomachinery Laboratories, 2008)
Induced draft (ID) fan systems often use louvers or variable inlet guide vanes to control the flow of exhaust through the fans. An ID fan system can be made more efficient by using a variable frequency drive (VFD) to control ...
Torsional Interharmonic Interaction Study of 75 MW Direct-Driven VSDS Motor Compressor Trains for LNG Duty
(Texas A&M University. Turbomachinery Laboratories, 2008)
In all-electric-driven liquefied natural gas (LNG) plants, converter-fed synchronous motors up to a power of 100 MW are being offered. During operation of compressor trains by a variable speed drive system (VSDS), integer ...
Prediction of Subsynchronous Rotor Vibration Amplitude Caused by Rotating Stall
(Texas A&M University. Turbomachinery Laboratories, 2008)
The prediction of rotating stall is one of the most important key technologies for compressors, especially high-pressure compressors. The operating ranges of compressors are restricted by rotating stalls because they my ...
Mechanical Seal and Support System Considerations for Negative Temperature Hydrocarbon Services: NGL Processing and Ethylene Production Focus
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are many challenging mechanical seal applications throughout industry and perhaps none more so than those with negative operating temperatures, more succinctly, a temperature value lower than zero on respective ...
Highlights of Draft API 610 12th Edition
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 610 Eleventh Edition, Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries, has been updated to the Twelfth Edition. The Eleventh Edition was identical to the ISO 13709 Second Edition; however, API ...
