INFLUENCE OF IMPELLER LEADING EDGE PROFILES ON CAVITATION AND SUCTION PERFORMANCE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The cavitation behavior and suction performance of a pump are
largely influenced by the geometry at the impeller eye. A
number of geometric factors at the impeller eye have an
influence on cavitation, such as, the inlet ...
Upgrading To Fully-Electric Actuation and Control of Steam Turbines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The use of an electric actuator for steam turbine governor valve operation is a cutting-edge technology in steam turbine control. With this design, the use of turbine oil for turbine speed control purposes is eliminated. ...
CO2 COMPRESSION AT WORLD’S LARGEST CARBON DIOXIDE INJECTION PROJECT
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Compressors for carbon dioxide (CO2) applications have been widely used in the O&G industry for urea production, enhanced oil recovery (EOR) and CO2 pipeline services for many years.
New environmental challenges have ...
Investigation of Corrosion Fatigue Phenomena in Transient Zone of Mechanical Drive Steam Turbines and its Preventive Measures
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
For mechanical drive steam turbines, the investigation
results of corrosion fatigue phenomena in the transient zone
are introduced, including basic phenomena on expansion
line and actual design and damage experience. ...
INLET FOGGING AND OVERSPRAY IMPACT ON INDUSTRIAL GAS TURBINE LIFE AND PERFORMANCE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The usage of an industrial inlet fogging and overspraying system on a 35,000 hp frame type industrial gas turbine in high pressure gas reinjection service was aimed to provide additional shaft power output and improved ...
PERFORMANCE ASSESSMENT OF GAS TURBINE DRIVEN CENTRIFUGAL COMPRESSOR TRAINS DERIVED FROM FIELD TESTING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Field testing of gas turbine driven centrifugal compressor
units at operational production facilities can provide valuable
information about the condition of the equipment. In this
paper, a case study is presented based ...
THE INFLUENCE OF THERMAL LOADING ON THE LEAK TIGHTNESS BEHAVIOUR OF HORIZONTALLY SPLIT CENTRIFUGAL COMPRESSORS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
For the purpose of maintenance requirements or for some applications in the chemical industry (for instance chlorine) the centrifugal compressor must be designed with a horizontally (axially) split casing.
Beyond the ...
Impact of Degradation on the Operational Behaviour of a Stationary Gas Turbine and in Detail on the Associated Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Degradation of stationary gas turbines is a quite often observed burden and can impact financial revenues of end-users significantly. In addition to the well-known occurrence of increased pressure losses in the intake ...
Experimentally Based Statistical Forced Response Analysis for Purpose of Impeller Mistuning Identification
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
A Root Cause Failure Analysis (RCFA) for repeated fourth stage impeller blade failures in a five stage centrifugal propane compressor used in Liquefied Natural Gas service is expanded upon by examining the amount and effect ...
POLYMER SEAL USE IN CENTRIFUGAL COMPRESSORS – TWO USERS’ EXPERIENCES OVER 15 YEARS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
For over 20 years now, the efficiency and reliability of centrifugal compressors has been enhanced by the application of engineered thermoplastic materials to the eye, shaft, and balance piston labyrinth seals. Traditionally ...
