Offline Chemical Wash for Internal Fouled Multistage Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
High pressure lean amine pump performance dropped within a span of about 1 month due to internal fouling. Fouling was caused by accumulation of iron sulphide. To address the fouling, pump would have been to taken out of ...
Introduction of SCC life time estimation for fir tree design on steam turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
MECHANICAL SEALING TECHNOLOGY USED IN MULTIPHASE PUMP APPLICATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Multiphase pumps have demonstrated their capability to operate successfully in pumping the product extremes, means 100% liquid up to 100% gas, as well as solids. This duty is difficult for a pump and thus even more difficult ...
Comparison of contacting wet and dry gas seals for main pipeline pumps in NGL services
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Recent incident reports and studies of pipeline equipment indicate that pump seal performance is likely at the root of a significant increase in releases to the environment. Although these releases are small compared to a ...
TURBOMACHINERY FOR HIGH CO2 APPLICATION: CHALLENGES, OBSTACLES AND LESSON LEARNT
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Turbomachinery is the heart of any platform, which generates power and compresses gas. However, the current practices of turbomachinery are entangled with various challenges and obstacles, which eventually affect the overall ...
THE USE OF ACOUSTIC COMB FILTERS TO AVOID CENTRIFUGAL COMPRESSOR DISCHARGE BLADE-PASS PULSATION INDUCED PIPING VIBRATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Centrifugal compressor blade-pass interaction periodic pulsation can cause acoustic resonance conditions and pipe vibrations in the suction and discharge lines of the compressor. A series of two or more progressively placed ...
Unexpected Vibration on a Centrifugal Compressor Caused by Vibration Probe Support
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
During the commissioning of a Main Air Compressor in an Air Separation Unit, the rotor showed increased radial vibrations at the Non-Drive End probe. The RCA revealed: The vibration resulted from the excitation ...
PNEUMATICALLY ACTUATED CONTROL VALVES IN OIL SYSTEMS: HARDWARE RECOMMENDATIONS AND TUNING CONSIDERATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Well designed and properly commissioned auxiliary systems are crucial to the reliability of rotating equipment. This paper addresses the upfront hardware selection and commissioning of pneumatically actuated control valves ...
Relation between wear ring clearances non-synchronous vibrations in BFW centrifugal pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A de-superheating boiler feed water pump was facing high vibration issue for last 19 years. Pump had been overhauled multiple times in past, but the issue was not resolved. Dominant frequency appearing in vibration spectrum ...
MECHANICAL DAMAGE TO PUMP IMPELLERS CAUSED BY LOW FLOW OPERATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
High- cycle fatigue damage imparted on a BB 5 pump impeller operating at low f low operation points was analyzed via numerical methods. A 1 - way Fluid- Structure interaction approach whereby a t ransient CFD subsequently ...
