A New Methodology for Verifying Pressurized Start-Up of Centrifugal Compressors Driven by Direct-On-Line Electric Motor by Leveraging String Test Results and Dynamic Simulation Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Fixed-Speed Electric Motors driving Centrifugal Compressors are designed considering the pressurized start-up as the most critical condition in terms of the torque requirement. Their capability is checked during the design ...
Development of New Heat Treatment Method to Impart High Creep Strength and High Toughness to Rotor Material for Condensing Steam Turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Higher temperatures in the HP section of the condensing Turbine requires rotor with high creep strength while low temperatures in the LP section require the rotor to have high toughness. The design basis for current rotor ...
Development of New On-Line Wash Oil Injection System for Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The process gas compressor is the most critical unit in ethylene plants and several types of contamination can often foul the
compressor flow path and plant production is significantly lost. In order to prevent this ...
High Reliability Pistons for Reciprocating Compressors with Validated Performance Modelling
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Piston ring leakage on reciprocating compressors is predictable due to defined leakage paths at the end gaps of piston rings. A new engineering approach quantifies the slippage and determines the dynamic pressure difference ...
API High Speed Balancing Acceptance Criteria and Pedestal Dynamics
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Acceptance criteria for high-speed balancing of turbomachinery are specified in API standards based on either pedestal velocity or shaft displacement. In addition to performing balancing, the measured displacements can ...
Additive Manufacturing and Topology Optimization Applied to Impeller to Enhance Mechanical Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The paper describes the link between additive manufacturing techniques and topological optimization design process.
An overview of Inconel718 printed material characteristics and as printed quality is given
Finally ...
New Challenges and Design for High Mach High Flow Coefficient Impeller for Large Size LNG Plant
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The new generation of LNG plant are moving toward a larger size, that mean larger compression stations, driven by higher power gas turbine that can arrive and exceed 100 MW. This increase of specific power means also ...
Successful Application of Nitrogen Turboexpanders-Compressors to Floating and Land-Based Liquified Natural Gas (LNG) Facilities
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
LNG production in the form of large land-based Mega-trains and floating production, storage and offloading facilities (FPSOs) have been of particular interest in recent years. The task of designing and building these ...
Testing of A 10 MWE Supercritical CO2 Turbine
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A new high temperature turbine was developed for use a sCO2 closed-loop recompression Brayton cycle. This turbine was developed for Concentrating Solar Power (CSP) applications (700+C), but its application includes traditional ...
Surge Exploration Tests and Second Quadrant Characteristic Dynamic Modeling on Full-Scale Centrifugal Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Surge exploration tests on a full-scale centrifugal compressor have been performed allowing an evaluation of the transient behavior and the mechanical robustness of the compressor even during a critical event such as Surge. ...
