The Use of Online Condition Monitoring in The Identification of Gas Compressor Rotor Damage
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Investigation and management of a rotordynamic issue affecting a production-critical centrifugal gas compressor. Following a restart of the compressor after a plant trip, radial vibration at the non-drive end of the shaft ...
A New Bolted Joint Profile, Optimized with FEA, Fixes a Leaking Propane Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
A bolted raised face Joint (with O-ring gasket) was failure prone. An axisymmetric FEA (finite element analysis) of the Joint verified why: the flanges were not stiff enough (not thick enough); too much flange rotation ...
INTRODUCTION TO DRY GAS SEALS AND SYSTEMS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
This tutorial presents an introduction to dry gas seals (DGSs) and their associated systems. DGSs are used as a shaft end seals for compressors and turbines, and they are installed on virtually all centrifugal compressors ...
Vibration Spike During Start up of an Integrally Geared Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
During workshop testing of a new 3-stage main air compressor, higher than expected vibration levels were detected at stage 1 and 2 at start up. They are high enough that the machine could not be brought to the full speed. ...
MODERN RISKS OF VARNISH AND DEFLAGRATIONS IN COMPRESSOR AND TURBINE LUBRICATION OIL SYSTEMS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
This presentation looks at a case study of a main air compressor that developed severe varnish ultimately linked to change in modern oil chemistry. It reviews actions that can be taken to minimize oil degradation resulting ...
L120: THERMO-STRUCTURAL TRANSIENT ANALYSIS OF A BOILER FEEDWATER PUMP
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
In the last few years, the installed capacity and production of electricity from all the renewable energies have significantly risen, supported by an ever-increasing spread of new energy policies all around the world. ...
DESIGN, TESTING, COMMISSIONING AND OPERATING EXPERIENCE OF A 2000HP HYDRAULIC TURBOCHARGER FOR ACID GAS RECOVERY PROCESS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Four sets of hydraulic turbocharger based energy recovery systems (2000 hp each) were successfully designed, manufactured, tested and commissioned for Acid Gas Recovery plants (AGR) in Saudi Arabia. The hydraulic turbocharger ...
Development and Application of Very High Flow Covered Stages for Process Centrifugal Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
For process centrifugal compressor applications, achieving higher flow rates through a given sized compressor can reduce capital cost while still meeting process requirements. Key technologies for enabling such higher flow ...
AN EFFECTIVE METHOD TO SEPARATE THE FORWARD AND BACKWARD NATURAL FREQUENCIES IN TURBOMACHINERY VIBRATION TEST MEASUREMENTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
As speed and power density increase, validation of analytical prediction with actual test data plays an important role to ensure avoidance of critical speeds in high-speed turbomachinery and a reliable design. For a typical ...
Operating Strategy of Oil - Flooded Screw Compressor Experiencing Oil Dilution in Fuel Gas System
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
Two 2,900 kW (3,900 hp) oil – flooded twin screw compressors deliver fuel gas from sour gas processing system to Gas Turbine Generators (GTG) at Banyu Urip oil production facility in Indonesia. The compressors operate with ...
