Air Compressor Site Performance Testing: Apparent Simplicity & Practical Complexity
(Texas A&M University. Turbomachinery Laboratories, 2004)
Air Compressor Site Performance Testing: Apparent Simplicity and Practical Complexity: The performance of a steam turbine driven air compressor deteriorated by 35% over a span of four months. This Case Study elaborates ...
New Technique For Online Washing Of Large Mechanical-Drive Condensing Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 2004)
To compete in today’s economic climate, petrochemical plants are strategizing on continuous long-term operation to reduce maintenance costs and increase productivity. This strategy has led some plants to go from eight years ...
High Pressure Oil-Injected Screw Gas Compressors (API 619 Design) For Heavy Duty Process Gas Applications.
(Texas A&M University. Turbomachinery Laboratories, 2004)
Oil-free screw compressors have been used for process gas application since the 1970s. Oil-flooded screw compressors have been used in many process related applications since the 1980s. Inclusion of oil-flooded screw ...
Determining The Root Causes Of Subsynchronous Instability Problems In Two Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2003)
This paper discusses the rotordynamic instability problems experienced with two separate centrifugal compressors. While the root causes of the instabilities are very different, the analysis methodology of reconciling the ...
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, ...
