(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Lubricating oil systems are vital to operation, long-term reliability, and availability of turbomachinery trains (or strings) which are strategic and expensive components of industrial plants. Sometimes, the entities that ...
-
(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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)This study starts by presenting a typical ethylene plant which will act as the ‘base plant’ for this case study. Then, a ‘low�emission’ ethylene plant is introduced which employs a new cracker technology having ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Laser cladding is gaining acceptance for restoration of turbine and compressor shafts, which has resulted in increased customer demand for laser cladding options. This has increased the number of laser welding suppliers, ...
-
(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 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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)The Oil and Gas industry is increasingly facing with more complex and hazardous operations. This is resultant from integration with a more complex feed and product properties as well as requirement for operation in harsher ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)The paper discusses the development of a novel impeller design concept that addresses changing requirements for radial centrifugal compressors applied in the polymer/downstream petrochemical industry. The impeller design ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)The governor actuator for a steam turbine was observed to be hunting and failed to maintain stable operating speed. The steam turbine is used to drive a centrifugal compressor for H2 service in a recycle loop. The extent ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Global demands for petrochemicals and green hydrogen usage are on the rise and are expected to continue for at least the next decade. Green hydrogen liquefiers are needed for the worldwide reduction of greenhouse gases and ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)The case study describes rotor crack detection using vibration measurements, documented on real case of Induction Motor driven Compressor Unit. The study highlights the complexity of rotor crack diagnostics as the primary ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Centrifugal compressor is the heart of upstream and downstream oil and gas operation as its ability to move large volume of fluid to its end destination. Centrifugal compressors are designed at certain range of 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 ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)Additive manufacturing has been utilized in an increasing number of applications for many different types of services. Cryogenic pump impellers can be manufactured to ASTM F3318 for AlSi10Mg in the HIP + T6 condition through ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)In a centrifugal compressor, interactions between impeller blades and stationary parts such as diffuser vanes will generate high frequency pressure pulsations. The frequencies of these pulsations, so called “blade passing ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)In rotating machinery, squeeze film dampers (SFDs) reduce rotor synchronous response amplitude motions, provide structural isolation and enhance rotordynamic stability. Compared to conventional squirrel cage supported SFDs, ...
