The Persistence of Retro-commissioning Savings in Ten University Buildings
(Energy Systems Laboratory, 2011-10-01)
A study was performed to evaluate how well energy savings persisted over time in ten university buildings that underwent retro-commissioning in 1996. Total annualized savings for all buildings in 1997 were 45(±2)% for ...
How Important Are The Protection Systems & Valve Design That Can Contribute To The Equipment Integrity On Reciprocating Compressors
(Texas A&M University. Turbomachinery Laboratories, 2012)
Analysis of Rotor Rub in a Large Centrifugal Refrigeration Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
The purpose of this case study is to present an investigation of substantial damage to the rotor of a large centrifugal propane refrigeration compressor that is installed in an 800 MTPA Ethylene plant. After ten years of ...
Field Investigation of Gearbox Vibration Due to Cracked Motor Rotor Bars
(Texas A&M University. Turbomachinery Laboratories, 2013)
Approximately one year after installing a new gearbox, vibration levels were gradually increasing. The tire plant requested that the gearbox manufacturer investigate under warranty. A field study was performed by an ...
Case Study of Morton Effect Experienced During a Mechanical Test of a Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 2013)
Axial Vibration for a Synchronous Motor Driven Gear and In-line Compressor Train
(Texas A&M University. Turbomachinery Laboratories, 2013)
Revamp/Re-Rate Design Considerations
(Texas A&M University. Turbomachinery Laboratories, 2013)
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 ...
Shop Rotordynamic Testing - Options, Objectives, Benefits and Practices
(Texas A&M University. Turbomachinery Laboratories, 2013)
Understanding the lateral rotordynamic behavior is critical in determining the reliability/operability of rotating equipment. Whether examining a centrifugal pump or compressor, steam or gas turbine, motor or generator, ...
CO2 Corrosion on Natural Gas Compressors: Criteria and Guidelines
(Texas A&M University. Turbomachinery Laboratories, 2013)
Liquid water and CO2 can easily lead to carbon steel corrosion, especially at high pressures. Corrosion can happen either during normal running or during pressurized standstill conditions. The present paper describes three ...
Electric Driven Centrifugal Compressor - Super Synchronous Vibrations of the High Speed Shaft Line: Observations, Assessment and Resolution
(Texas A&M University. Turbomachinery Laboratories, 2013)
An unacceptable vibratory behavior was encountered in 2012 during the full load string test of an electric driven centrifugal compressor. The vibrations were observed on the high speed part of the shaft line and both ...
