Vibration Diagnostic of Steam Turbine Intermittent Rubbing
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
A special purpose steam turbine has started to experience intermittent radial vibration spikes. The turbine is used to drive a Hydrogen Recycle Gas Compressor in Aromatics unit. No abnormality observed on the compressor ...
TURNING GEAR MOTOR FAILURES, CONFIRMED BY MODEL BASED VOLTAGE & CURRENT METHOD
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
This technical brief aims to showcase relevant information related to Model-Based Voltage and Current (MBVI) method. The paper discusses several fatal failures on the Turning Gear Motor (TGM) over the short time period of ...
Steam Turbine High Axial Displacement due to Governor Actuator Filter Clog
(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 ...
Vibration issue on Compressor in a Nitric Acid Plant (Part 2)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
“Part 1 of the case history for this return to service follows on from the 2021 ATPS “ presentation which covered off the Expander related issue (labyrinth seal rubs) preventing the NAP 2 plant from successfully re ...
TURBOEXPANDERS IN PETROCHEMICAL INDUSTRY ADVANCE TECHNOLOGY FOR GREEN HYDROGEN LIQUEFACTION
(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 ...
Catastrophic Mechanical Seal Failure Leading to Loss of Primary Containment (LOPC)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
Usage of mechanical seal is widely used in rotating equipment especially pump It prevents fluid or product of the pump from leaking to atmosphere Consequence of seal leaking will be more critical if the product itself is ...
CENTRIFUGAL COMPRESSOR PROLONGED LOW FLOW OPERATION CONSIDERATION FOR OPERATORS
(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. ...
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 ...
