Pumping Oil Sand Froth
(Texas A&M University. Turbomachinery Laboratories, 2004)
Froth is the basis to the extraction of bitumen from oil sand. Its components include sand, bitumen, water, and air. The technology of extraction and processing is evolving toward lower temperature of operation where the ...
Demonstration Of Cavitation Life Extension For Suction-Stage Impellers In High Energy Pumps
(Texas A&M University. Turbomachinery Laboratories, 2004)
Cavitation occurring in high-energy pump impellers often results in material erosion and system instabilities. Excessive erosion rates compromise life and increase ownership costs through higher maintenance and reduced ...
Determining The Cause Of Bearing Failures In Circulating Water Pump Motors
(Texas A&M University. Turbomachinery Laboratories, 2004)
Eight vertical circulating water pumps are used to circulate condenser water at the generation station in a nuclear power plant. The pump installation is pictured in Figure 1. The motor pump system is arranged vertically ...
Abnormal Vertical Pump Suction Recirculation Problems Due To Pump-System Interaction
(Texas A&M University. Turbomachinery Laboratories, 2004)
It is well documented that the proper operation of vertical centrifugal pumps is greatly dependent upon the entire pump/piping system, which includes the piping geometry and the system operating conditions. Oftentimes, ...
Mechanical Seals With Wavy Sic Faces For A Severe Duty NGL/Crude Pipeline Application
(Texas A&M University. Turbomachinery Laboratories, 2004)
Mechanical seals were developed for a pipeline with demanding operation conditions. Natural gas liquids (NGL), refined products, and crude oil are pumped in batch mode. Seal pressure varies over a wide range and the pumps ...
Multistage Pump Efficiency Gains Through The Elimination Of The Seal Chamber Pressure Equalization Line
(Texas A&M University. Turbomachinery Laboratories, 2004)
The majority of horizontally split multistage pumps were designed when packing was the only cost effective method of sealing the pumpage from atmosphere. As a result, even modern pumps employ a stuffing box pressure ...
Centrifugal Pumps In Heated Bitumen Pipeline Service
(Texas A&M University. Turbomachinery Laboratories, 2004)
World scale deposits of oil sands (bitumen) in North Alberta are being developed to extract hydrocarbons from the sand. A pilot facility was built to pump raw heavy tar-like bitumen in a heated state through an insulated ...
Selection Of Large Water Transport Pumps And Field Experiences
(Texas A&M University. Turbomachinery Laboratories, 2004)
This paper covers the selection criteria with respect to suction behavior and optimum efficiency of large water transport pumps to meet various system requirements. Simplicity of pump design and operating behavior of pumps ...
Enhanced Multiphase Flow Predictions In Twin-Screw Pumps
(Texas A&M University. Turbomachinery Laboratories, 2004)
In oil field applications it is often required to pump oil, gas, and water as mixtures rather than separating the fluid. Although the performance prediction of twin-screw pumps on liquids is well established, the prediction ...
Grouting Of Small Pump Baseplates? Is It Worth It?
(Texas A&M University. Turbomachinery Laboratories, 2004)
For pump installation most experts recommend installing conventional metallic baseplates on concrete foundations and securing them to the foundation with a combination of anchor bolts and epoxy grout. Many papers have been ...
