World’s First Aeroderivative Based LNG Liquefaction Plant – Design, Operational Experience and Debottlenecking
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The Darwin LNG Facility is the world’s first liquefaction
facility to utilize high efficiency aeroderivative gas turbines for
its refrigeration compressors. The plant’s design, startup,
successful operation for over ...
ON-SITE DETERMINATION OF THE CONTROL LINE FOR INTEGRALLY GEARED COMPRESSORS FOR AVOIDANCE OF IMPELLER FATIGUE FAILURES
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
In this lecture a root cause analysis (RCA) is presented for a fatigue failure of a semi-open impeller of an integrally geared compressor. The compressor had been in service for about one year in an air separ
3rd stage impeller.
GAS TURBINES DURABILITY IN HARSH ENVIRONMENTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The performance and durability of industrial gas turbines are
strongly dependent on the operating conditions and the
environment in which they function at. Engine performance and
durability must be equally considered ...
FLUID FILM BEARINGS FUNDAMENTALS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Bearings constitute one of the most critical components in
turbo and rotating machinery today. Their influence on the
rotordynamic performance, life, and reliability of the machine
cannot be ignored. Many of the problems ...
NEW APPROACH TO TORSIONAL VIBRATION MONITORING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
This paper presents a summary of the authors' experience
gained from implementation of model-based monitoring
systems for LNG string vibration. The development of a novel
train torsional vibration monitoring approach ...
Fifteen Years of Field Experience in LNG Expander Technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
From the earliest days of gas liquefaction, the
thermodynamic process advantage of employing cryogenic
liquefied gas expanders in place of throttling valves was very
well recognized. The available technology was unable ...
RECIPROCATING COMPRESSOR CONDITION MONITORING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Technology for reciprocating compressor condition monitoring has been around since the 1950’s, however until the last 20 years or so it seemed that only the pipeline companies spent much effort on this activity. Technology ...
Large Vibrations on a Centrifugal Compressor Caused by High Windage Heating on a Flexible Coupling–Root Cause Analysis and Solutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Background: 2 parallel trains consisting of a Low Pressure (LPC) and High Pressure (HPC) compressors were supplied for an offshore reinjection application near the coast of Angola. During the commissioning on site large ...
Seal Condition Monitoring Principles
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
As many of you have experienced throughout your career, Mechanical Seals are the number 1 failed component within pumps. So, how do we fix that? In this tutorial, we will discuss why seals are the # 1 failed component, but ...
