Desktop Use Of Computational Fluid Dynamics To Design And Troubleshoot Compressors And Turboexpanders.
(Texas A&M University. Turbomachinery Laboratories, 2003)
For several decades, turboexpander designers have relied on experience and traditional design tools to create their products. Recent advances in CFD (computation fluid dynamics) software and desktop computing power have ...
Solving Stability Problems While Commissioning A 100 MW Turbine Generator Set.
(Texas A&M University. Turbomachinery Laboratories, 2003)
A new cogeneration installation was in the process of being commissioned when severe subsynchronous vibration was detected on the generator during no load tests. Subsequently, two rotordynamics problems were discovered. ...
Steam Turbine Corrosion and Deposits -- Problems and Solutions
(Texas A&M University. Turbomachinery Laboratories, 2008)
This tutorial paper discusses the basics of corrosion, steam and deposit chemistry, and turbine and steam cycle design and operation - as they relate to steam turbine problems and problem solutions. Major steam turbine ...
Selection of Materials and Material Related Processes for Centrifugal Compressors and Steam Turbines in the Oil and Petrochemical Industry
(Texas A&M University. Turbomachinery Laboratories, 2008)
In today’s marketplace the selection of materials for the various components for centrifugal compressors and steam turbines is very competitive and an important factor in the overall cost and delivery of the product. This ...
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, ...
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 ...
