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 ...
Reliability Improvement At Petrotrin Refinery - Pumps At No. 8 CDU. 1997 To 2003
(Texas A&M University. Turbomachinery Laboratories, 2004)
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 ...
Solution To Corrosion/Nigh NSS Problem At Petrotrin Refinery
(Texas A&M University. Turbomachinery Laboratories, 2004)
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, ...
Introduction To Sealing Mixers In The Pharmaceutical And Biotech Industries
(Texas A&M University. Turbomachinery Laboratories, 2004)
While other segments of industry have slowed the biotech and pharmaceutical industries are emerging as strong growth industries. To participate in this promising growth the mechanical seal manufacturers have begun to focus ...
Overview Of API 682 And ISO 21049
(Texas A&M University. Turbomachinery Laboratories, 2004)
APIs recent release of Standard 682 Second Edition and the pending release of API 682 Third Edition and ISO 21049 represent a major revision to this standard. These revisions have greatly expanded the scope of the standard ...
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 ...
