Investigating & Improving the Drooping Curve of A Two-Stage Feed Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A two-stage between-bearing pump of the upgraded material was supplied to replace the existing machine. The pump utilized a higher number of impeller blades to obtain higher efficiency at its design point, but exhibited a ...
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 ...
Drivetrain Protection Through Coupling Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
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 ...
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 ...
