Troubleshooting Turbomachinery Problems Using A Statistical Analysis Of Failure Data.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The use of statistical techniques to investigate machinery failure data is one of the most powerful troubleshooting tools available to the turbomachinery engineer. This analysis tool can provide a great deal of information ...
Retrofit, Upgrade, And Demothball Of Two Crentrifugal Compressor Trains.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design premise in upgrading two operating plants for more compression capability is discussed.
The first is a syn gas plant designed for 1000 tons/day of methanol but converted to syn gas only for a primary acetic ...
Understanding The Vibration Forces In Induction Motors.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Squirrel cage induction motors have been used extensively in industry for over 50 years. While it appears that vibration problems are more pronounced nowadays, certain basic construction features have always existed and ...
Magnetic Bearings And Dry Gas Seals - A Process Compressor Application.
(Texas A&M University. Turbomachinery Laboratories, 1990)
The design considerations and features along with manufacturing and operating experiences encountered on a multistage centrifugal process compressor incorporating a dry gas seal and active magnetic bearings immersed in the ...
Considerations In Hot And Cold Alignment And Couplings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Hot and cold alignment techniques are addressed, with graphical plotting of reverse dial indicator alignment maps. An alignment program with a two sets of data for cross checking and suggested proper tooling and procedures ...
Magnetically Driven Centrifugal Pumps Eliminating Seal Problems In Refinery And Chemical Processing Plant Equipment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Centrifugal pump design plays an essential role in the safe operation of any refinery or chemical processing plant. In analyzing the performance of centrifugal pumps, pump operating time to failure is almost always limited ...
Pump Rotor Critical Speeds Diagnosis And Solutions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Delmarva Power Indian River Power Station’s Unit 4 has had boiler feed pump reliability problems since startup in 1980. The pump has been rebuilt nine times with post overhaul operability ranging from 30 minutes to 16 ...
New Developments In Standby Seals For Applications For Environmental Sensitive Duties
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Over the years, close attention has been paid in process facilities to the pumping of light hydrocarbons. Leakage of these products can and do cause environmental and health threatening situations. Since attention has been ...
Pinch Application- Heat Pump Study in a Food Plant
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
A pinch analysis normally requires a large
amount of process information. However,
this information usually adds to the overall
understanding of the process and utility
system. This better understanding of the
process ...
Investigation of Sulfur Removal by Direct Limestone Injection
(Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1990-06)
Sulfur removal by direct injection of calcium-based sorbents is an attractive option for emerging coal utilization technologies. Recent experimental results indicate the feasibility of capture by direct injection into hot ...
