Gas Turbine Performance and Maintenance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this tutorial, we will address the basic characteristics of
each of the components in a gas turbine (compressor,
combustor, gas generator turbine, power turbine) and the
impact of typical control limits and control ...
HF Acid Alkylation Processes: Pump and Mechanical Seal Application and Design Considerations for Increased Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Hydrofluoric (HF) acid is an extremely corrosive solution commonly found in many oil refineries where it is used as a catalyst in the production of high octane gasoline blending stock. HF acid is almost synonymous with the ...
Examination of Methods of Dry Gas Seal Supply, Regulation, and Monitoring
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Compressor Dry Gas Seal Failure is a common issue that affects Turbomachinery train availability. Since most
turbomachinery trains are un-spared critical assets, unscheduled shutdowns have a major impact to the operating ...
Erosion Prediction of Gas Turbine Compressor Blades Subjected to Water Washing Process
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Blade fouling is a relevant problem in turbomachinery applications.
It affects both compressors and turbines. In the first
case, fouling can be generated by the presence of dust, ashes or
brackish air (in offshore ...
Drivetrain Protection Through Coupling Design

This paper is designed to explain types of coupling advanced features and modifications used in turbomachinery, where drivetrain protection is desired. The subject includes a review of flexible coupling types, their ...
Condition Monitoring of Turbomachinery with Internet-of-Things (IOT)
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Condition monitoring is one of the critical process in turbomachinery equipment. As a factory equipment, Turbormachinery mostly transfers data via controllers such as programmable-logic-controller (PLC). Parameters of the ...
Digitalisation in Medium Voltage Variable Speed Drive Systems to Increase Productivity in Oil & Gas Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this paper we talk about influence of digitalization in process industries and how it can be adapted to Medium Voltage drive systems. Various aspects of digitalization like monitoring, preventive maintenance and using ...
Conversion from Centrifugal to Rotary Positive Displacement Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A major U.S. pipeline company was experiencing multiple problems at a crude pipeline intermediate pump station. The application seemed ideal for a rotary positive displacement (PD) pump. Working with a vendor and seeing a ...
Investigation and Resolution of Propane Compressor High Axial Position Alarm
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Propane compressor in Propane Dewaxing Unit was experiencing intermittent high axial spikes coinciding with the chiller swing. The axial spikes were due to compressor surge caused by sudden drop in
flow during chiller ...
