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 ...
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 ...
Steam Turbine Pipe Strain Case Study
(Texas A&M University. Turbomachinery Laboratories, 2008)
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
Rotordynamic Design Audits of AMB Supported Machinery
(Texas A&M University. Turbomachinery Laboratories, 2008)
Active magnetic bearings (AMBs) are a mature bearing technology that is being applied to many new turbomachines. They have become the bearing of choice for most new turboexpander applications. They are seen as a key enabling ...
Dynamic Instabilities in Industrial Compression Systems with Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 2008)
Compression systems involving centrifugal compressors are designed and operated in a manner to eliminate or minimize the potential for compressor surge, which is a dynamic instability that is detrimental to the integrity ...
Life Cycle Assessment of Turbomachinery for Offshore Applications -- Updated with Field Data
(Texas A&M University. Turbomachinery Laboratories, 2008)
About 40 to 50 percent of the power required for the operations of a typical offshore oil and gas platform is used for gas compression. Miranda and Brick (2004) described a comprehensive procedure that could be applied to ...
