Case Study on Investigation and Resolution of High Lube Oil Pump Bearing Temperature for Off Spec. Condensate Recycle Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Off Spec Condensate Recycle Pumps on an onshore gas production facility exhibited high lube oil temperature in pump bearing housing that exceeded the alert limits since commissioning. A Structured Root Cause Analysis was ...
ANNULAR CLEARANCE GAS SEALS: MODELS AND MEASUREMENTS FOR LEAKAGE, FORCE COEFFICIENTS AND THEIR EFFECT ON ROTOR STABILITY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...
Key Differences between Steam Turbines and Electric Motors as Main Compressor Driver in Olefins Plants
(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 ...
Application of Polycrystalline Diamond (PCD) Bearing for Reactor Circulation Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
The axial flow loop reactor pump installed in a polymer unit facilitates slurry circulation in the reactor. The pump is installed with triple mechanical seal having API seal flushing plans 32, 53C and 52. The seal cartridge ...
Implementation of Voted Flame Detectors to Prevent Spurious Fire Detection in Gas Turbines Enclosures.
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Fire detection inside Gas Turbine enclosures is a safety critical component to prevent unwanted consequences should a fire occur within the enclosure. The standard design and implementation strategy remains by and large ...
PITTING CORROSION LED TO CATASTROPHIC GAS TURBINE COMPRESSOR BLADE LIBERATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A gas turbine's intake system usually has 3 4 stages of filtration After the primary and secondary filter, the final marine vane separator ( is used These filters are designed to keep rainwater debris, and salt from entering ...
HIGH SPEED PUMP: MECHANICAL SEAL BAD ACTOR RESOLUTION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Case study include a vertical pump in sour water service running at high speed of 17200rpm. Pump originally equipped with single seal & Plan 21 configuration since day one. In 2018, as part of a reliability upgrade, seal ...
Wet Refrigeration Screw Compressor Failure due to Liquid Slugging
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A wet screw refrigeration compressor had three failures and all failures were related to male rotor High- High axial displacement. The failure was concluded to be due to liquid propane formation at compressor suction, ...
