Torsional Rotordynamics of Machinery Equipment Strings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Root Cause Failure Analysis for Machinery and Piping Part 1: Introduction to RCFA
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
MODELING OF PRESSURE DYNAMICS DURING SURGE AND ESD
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Centrifugal compressors operability at low flow is normally limited by the onset of surge that occurs when operating near maximum achievable pressure rise. Surge is characterized by large amplitude and periodic pressure ...
IMPACT OF PIPING IMPEDANCE AND ACOUSTIC CHARACTERISTICS ON CENTRIFUGAL COMPRESSOR SURGE AND OPERATING RANGE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The performance of a centrifugal compressor is usually defined by its head versus flow map, limited by the surge and stall regions. This map is critical to assess the operating range of a compressor for both steady state ...
A PROBABILISTIC APPROACH FOR COMPRESSOR SIZING AND PLANT DESIGN
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
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, ...
STALL INDUCED AERODYNAMIC FORCING AND ROTOR VIBRATIONS IN A MULTISTAGE CENTRIFUGAL COMPRESSOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The Oil & Gas industry is looking with increased interest
at solutions for improving operating flexibility of centrifugal
compressors. The stable operation of a compressor stage or
machine is generally limited at the ...
EFFECTS OF SUPPORT STRUCTURE DYNAMICS ON CENTRIFUGAL COMPRESSOR ROTOR RESPONSE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Accurate modeling of complicated dynamic phenomena characterizing rotating machineries represents a critical aspect in the rotor dynamic field. A correct prediction of rotor behavior is fundamental to identify safe operating ...
Investigation and Resolution of Governing Valve Linkage Failure for Compressor Drive Steam Turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Fatigue failure of Governing Valve Linkage Rod end bearing and wear marks on several parts was observed on a extraction steam turbine (driving a centrifugal compressor) after it was in service for more than 9 year. The top ...
Glycol-Based Lube Oil Behavior & Its Effects In Fuel Gas Compression System
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Oil-flooded screw compressors (2 units x 100% duty) deliver fuel gas from AGRU Absorber at saturated condition to GTG to sustain oil production facilities @ ~33 MW power demand. Each Fuel Gas Compressor (FGC) is rated for ...
