New Designs And Applications For Increased Power Recovery And Improved Reliability In FCC Expanders.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Fluid catalytic cracking (FCC) hot gas expanders were developed in the early 1960s and were improved in the early 1980s with updates in airfoil technology. Since then, units designed for pressure ratios of approximately ...
Practical Use Of Rotordynamic Analysis And Troubleshooting Skills To Correct A Long-Term Synchronous Vibration Problem In An Overhung Turboblower.
(Texas A&M University. Turbomachinery Laboratories, 2002)
The two subject blowers operate in parallel to circulate wet chlorine gas. Both units had large synchronous vibrations that led to multiple bearing failures. After simple rotordynamic studies failed to identify the problem, ...
Current And Vibration Monitoring For Fault Diagnosis And Root Cause Analysis Of Induction Motor Drives.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Induction motor drives are the most widely used electrical drive systems and they typically consume 40 percent of an industrialized nation’s total generating capacity. In the USA the total generating capacity is approximately ...
Assessment Of Technology And Economic Benefits Of Reciprocating Machine Condition Monitoring And Diagnostic Systems.
(Texas A&M University. Turbomachinery Laboratories, 2002)
The ongoing trend toward automation of the oil, gas, and chemical industry has significantly changed the entire industry. Digital control systems utilizing advanced computer technologies are installed to manage integrated ...
Rotordynamic Stability Measurement During Full-Load, Full-Pressure Testing Of A 6000 Psi Reinjection Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Full-load, full-pressure rotordynamic stability measurements were conducted on a seven-stage, back-to-back centrifugal compressor. To validate rotordynamic predictions, the rotor was excited while operating at full load ...
Compressor Discharge Pipe Failure Investigation With A Review Of Surge, Rotating Stall, And Piping Resonance.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Rotating stall, even with multiple cells, can contribute to piping excitation due to acoustic energy traveling down the pipe as a plane wave. The main objective of the paper is to describe causes and solution of fatigue ...
Rotordynamic Tests Of A Flexible Rotor On Flexure Pivot Journal Bearings And Stability Correlation With Frequency Dependent Characteristics.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A series of performance, unbalance response, and stability tests were performed on a flexible rotor incorporating two flexure pivot tilt-pad journal bearings, followed by a theoretical correlations using synchronous and ...
New Technologies Of Synthesis Gas Compressor Drive Steam Turbines For Increasing Efficiency And Reliability.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Recently, synthesis gas compressor drive steam turbines have required upgrading to increase efficiency and reliability for saving both operation and maintenance costs in many ammonia plants. This paper introduces the latest ...
Compressor Seals For Hydrogen Recycle Service.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Hydrogen recycle service has presented a special challenge for centrifugal compressors and particularly the casing seals. Typical problems include the presence of liquids (condensables and water), hydrogen sulfide, chlorides, ...
