World's First 10,000 PSI Sour Gas Injection Compressor
(Texas A&M University. Turbomachinery Laboratories, 2008)
This paper traces the development of the original sour gas injection (SGI) concept, the methodology used for managing risks, detailed design and testing of compression train components, compressor train shop string tests, ...
Torsional Vibration Problem with Motor/ID Fan System Due to PWM Variable Frequency Drive
(Texas A&M University. Turbomachinery Laboratories, 2008)
Induced draft (ID) fan systems often use louvers or variable inlet guide vanes to control the flow of exhaust through the fans. An ID fan system can be made more efficient by using a variable frequency drive (VFD) to control ...
Torsional Interharmonic Interaction Study of 75 MW Direct-Driven VSDS Motor Compressor Trains for LNG Duty
(Texas A&M University. Turbomachinery Laboratories, 2008)
In all-electric-driven liquefied natural gas (LNG) plants, converter-fed synchronous motors up to a power of 100 MW are being offered. During operation of compressor trains by a variable speed drive system (VSDS), integer ...
Prediction of Subsynchronous Rotor Vibration Amplitude Caused by Rotating Stall
(Texas A&M University. Turbomachinery Laboratories, 2008)
The prediction of rotating stall is one of the most important key technologies for compressors, especially high-pressure compressors. The operating ranges of compressors are restricted by rotating stalls because they my ...
Verification Full Load Test Of 900 T/H (1,980,000 LB/H) Large Mechanical Drive Steam Turbine For ASU Up To 200 MW (268,000 HP) Based On Principle Of High Scale Model Similarity.
(Texas A&M University. Turbomachinery Laboratories, 2009)
In 2009, the authors designed a compressor drive steam turbine for air separation units (ASU) application up to 200 MW (268,000 hp), using large 500 mm (19.7 inch) blade rows, which have a low-pressure (LP) flow capacity ...
Centrifugal Compressor Applications - Upstream And Midstream.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Centrifugal compressors are used in a large number of different compression application. This tutorial addresses applications for centrifugal compressors in the upstream and midstream sector, such as LNG compression, ...
The Effects Of Pulsations On The Surge Margin Of Centrifugal Compressors In Stations With Both Reciprocating And Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Mixed operation with both centrifugal and reciprocating compressors in a compression plant poses significant operational challenges as pressure pulsations and machine mismatches lead to centrifugal compressors’ instabilities ...
Rotordynamic Stability Of A 9500 Psi Reinjection Centrifugal Compressor Equipped With A Hole Pattern Seal-Measurement Versus Prediction Taking Into Account The Operational Boundary Conditions.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Extensive stability measurements were performed during the full-load, full-pressure factory testing of a five-stage inline centrifugal compressor. The compressor, tested up to a maximum discharge pressure of 655 bar (9,500 ...
Steam Turbine Pipe Strain Case Study
(Texas A&M University. Turbomachinery Laboratories, 2008)
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
Radar-Based Sensors - A New Technology For Real-Time, Direct Temperature Monitoring Of Crank And Crosshead Bearings Of Diesels And Hazardous Media Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2006)
Surveys aiming to isolate the main causes of severe damage of large machines such as reciprocating compressors and diesel engines clearly indicate the need for a reliable method to perform real-time monitoring of the ...
