Winter Vibration Problems on VS6 Booster Pumps and Solutions
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background: Three multistage canned vertically-suspended pumps are installed at Kerrobert, Canada to transfer crude oil. The pumps are driven by 1000 HP vertical motor at 885 RPM. Problem Statement: The installed pumps ...
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 ...
Mechanical Seal and Support System Considerations for Negative Temperature Hydrocarbon Services: NGL Processing and Ethylene Production Focus
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are many challenging mechanical seal applications throughout industry and perhaps none more so than those with negative operating temperatures, more succinctly, a temperature value lower than zero on respective ...
Highlights of Draft API 610 12th Edition
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 610 Eleventh Edition, Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries, has been updated to the Twelfth Edition. The Eleventh Edition was identical to the ISO 13709 Second Edition; however, API ...
Load Dependent Critical Speed
(Texas A&M University. Turbomachinery Laboratories, 2010)
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, ...
