A Probabilistic Approach for Compressor Sizing and Plant Design
(Texas A&M University. Turbomachinery Laboratories, 2013)
Equipment sizing decisions in the Oil and Gas Industry often have to be made based on incomplete data. Often, the exact process conditions are based on numerous assumptions about well performance, market conditions, ...
Coupling Credible Failure Modes and Owner Options to Intervene
(Texas A&M University. Turbomachinery Laboratories, 2013)
While all machine component failures can impact reliability, cost and production, some like coupling failures may have safety risks for personnel. Intervention requires us to build appropriate steps into our machine and ...
Limitations of ASME PTC 10 in Accurately Evaluation Centrifugal Compressor Thermodynamic Performance
(Texas A&M University. Turbomachinery Laboratories, 2013)
The American Society of Mechanical Engineers (ASME) “Performance Test Code on Compressors and Exhausters,” ASME PTC 10-1997, has served worldwide as the standard for determining centrifugal compressor thermodynamic performance ...
History of Gear Failures in a Steam Turbine Driven Integrally Geared Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Innovative Design in Expander Wheel-Shaft Attachment Replaces Hirth Coupling for High Speed, High Temperature and High Power Applications
(Texas A&M University. Turbomachinery Laboratories, 2013)
Expander-Generator unit for a geothermal power plant application experienced ongoing failures during a ten year period. The longest run cycle for the machine was 18 months yet with less than 10 MW power production. The ...
Capacity Improvement of Large, Two Stage Diaphragm Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Two stage diaphragm compressor is used to pressurize a process gas stream. As delivered, compressor produced less than 75% of the required flow rate at the specified suction and discharge conditions. Improvement Goal: ...
Impact of Piping Impedance and Acoustic Characteristics on Centrifugal Compressors Surge and Operating Range
(Texas A&M University. Turbomachinery Laboratories, 2013)
Case Study: Bearing Frosting and the Unique Occurrence on a Geared Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Successful Online and Offline Cleaning of Steam Turbines With and Without Disassembly
(Texas A&M University. Turbomachinery Laboratories, 2013)
Compressor Oil Flow Case Study
(Texas A&M University. Turbomachinery Laboratories, 2013)
This is a case study of a new motor-gear-compressor train installation in which the lube oil pressure became an issue during commissioning and startup. This case study will bring to light the hidden communication gaps that ...
