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 ...
GAS TURBINE COMPRESSOR INLET AIR FILTERS PERFORMANCE COMPARISON
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Crude Oil Non-Pusher Secondary Seal
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Crude oil pipeline pumps traditionally suffer from seal leakage due to the fretting or wearing of the dynamic O-ring. A new concept secondary seal has been developed to eliminate this fretting occurrence. All major seal ...
AN OVERVIEW OF MACHINERY IN ENERGY STORAGE AND HYDROGEN APPLICATIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Decarbonization of electric power infrastructure requires the development of cost-effective, sustainable, and reliable energy storage technologies that are capable of many Megawatts or Gigawatts of output and long storage ...
