Revamp/Re-Rate Design Considerations
(Texas A&M University. Turbomachinery Laboratories, 2014)
This tutorial paper describes the mechanical and aerodynamic factors that must be considered when revamping, re-rating or upgrading a centrifugal compressor. The possible motivations for choosing to revamp existing ...
New Active Magnetic Bearing Requirements for Compressors in API 617 Eighth Edition
(Texas A&M University. Turbomachinery Laboratories, 2014)
Active magnetic bearings (AMBs) are being used for an increasing number of compressors in the oil and gas industry. The applications include cryogenic compressor-expanders, subsea processing, pipeline and other process ...
Fundamentals of Signal Processing Applied to Rotating Machinery Diagnostics
(Texas A&M University. Turbomachinery Laboratories, 2014)
Rotating machinery diagnostics have been, and will be, a critical area in the Oil and Gas Industry. Though in the early days oscilloscopes and spectrum analyzers were typically used to analyze vibration data, in recent ...
Monitoring a Tandem Dry Gas Seal's Secondary Seal
(Texas A&M University. Turbomachinery Laboratories, 2014)
Rotating equipment and instrument engineers working with dry gas seals should attend this tutorial to increase their knowledge of methods for monitoring secondary seals. Over the last several years a number of compressor ...
Gas Turbine Degradation
(Texas A&M University. Turbomachinery Laboratories, 2014)
There is a strong incentive for gas turbine operators to minimize and control performance degradation, as this directly affects profitability. The area of gas turbine recoverable and non-recoverable performance degradation ...
Combustion, Fuels and Emissions for Industrial Gas Turbines
(Texas A&M University. Turbomachinery Laboratories, 2014)
It is important that gas turbines used in Oil & Gas applications can burn a wide variety of fuels with the minimum impact on the environment or economics. Many types of gaseous and liquid fuels that can be used in Gas ...
Save Your Centrifugal Machinery During Commissioning
(Texas A&M University. Turbomachinery Laboratories, 2014)
During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious ...
Subsea Compression Applications - Panel Session
(Texas A&M University. Turbomachinery Laboratories, 2014)
The use of Subsea gas compression technology for subsea re-injection and/or gas transport boosting represents a new and exciting application for rotating equipment, which will allow new gas/condensate field production ...
A Review of Aerodynamically Induced Forces Acting on Centrifugal Compressors, and Resulting Vibration Characteristics of Rotors
(Texas A&M University. Turbomachinery Laboratories, 2014)
There are several sources of non-synchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, ...
Technology Machinery Engineers Need to Know to Work Effectively Subsea: Session 1 and Session 2
(Texas A&M University. Turbomachinery Laboratories, 2014)
More and more equipment is being installed subsea. These include valves and manifolds, chokes, pumps, compressors, separators, etc. These installation are needed to effectively produce underwater oil and gas deposits. As ...
