Visualization Study Of The Performance Breakdown In The Two-Phase Performance Of An Electrical Submersible Pump
(Turbomachinery Laboratory, Texas A&M University, 2010)
Barrios (2007) conducted an experimental work in which was demonstrated that the two-phase stage performance of an electrical submersible pump (ESP) is related to the impeller gas and liquid flow pattern as mentioned by ...
Upstream Pumping Technology In Centrifugal Pump Mechanical Sealing Applications—Field Experience With High Duty Seawater Injection Pumps
(Turbomachinery Laboratory, Texas A&M University, 2010)
Among the technologies developed for oil and gas production centrifugal pump sealing applications, active lift technology is one of the most promising. The reliability of any centrifugal pump in a critical application is ...
Risk-Based Pump Seal Selection Guideline Complementing ISO 21049/API 682
(Turbomachinery Laboratory, Texas A&M University, 2010)
The API 682 (2004) seal “Arrangement” selection logic is a questionnaire posing question about customer experience, local regulations and seal leakages requiring a vendor, customer iterative dialogue. The proposed selection ...
Improving The Reliability Of A Decoking Jet Pump Train With A Hydrodynamic Variable Speed Drive
(Turbomachinery Laboratory, Texas A&M University, 2010)
Delayed coking is a refining process that consists of the upgrading of petroleum residues into lighter and more valuable hydrocarbon fractions by promoting thermal cracking on the residue stream. Petroleum coke is a ...
An Improved Heat Soak Calculation For Mechanical Seals
(Turbomachinery Laboratory, Texas A&M University, 2010)
Heat soak is defined as heat transfer from the metal of a seal chamber to the fluid within the seal chamber. Many variables affect heat soak including materials, surface configurations, and film coefficients. Heat soak can ...
Improving Reliability In A High Static Head System Through VFD Application
(Turbomachinery Laboratory, Texas A&M University, 2010)
The static head content in the total head of a pumping system (static head factor - fHS) plays an important role on energy and reliability potential gains attainable with the use of variable speed (VS) controls in pumping ...
Assessment Of Wear Erosion In Pump Impellers
(Turbomachinery Laboratory, Texas A&M University, 2010)
Wear erosion needs special attention in pump design as it can lead to severe damage of the pump and restrict its lifetime significantly. It therefore determines to a large extent the selection of a pump. During the design ...
Pressurized Dual Mechanical Seals Supporting Piping Plan Developments
(Turbomachinery Laboratory, Texas A&M University, 2010)
The American Petroleum Institute recognizes four auxiliary piping plans for supporting pressurized dual wet mechanical seals. There is limited published information guidance as to which plan will offer the most suitable ...
