Maximizing An Ethylene Plant's Turbomachinery Reliability.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The ethylene plant in DuPont's major petrochemical complex
in Orange, Texas was designed and built in the late 1960s,
using the latest proven technology of that period. From plant
startup in 1967 to 1981, there were ...
Instrumented Couplings: The What, The Why And The How Of The Indikon Hot-Alignment Measuring System
(Texas A&M University. Gas Turbine Laboratories, 1980)
The Analysis Of Surge
(Texas A&M University. Gas Turbine Laboratories, 1980)
Recently, considerable attention has been given to the phenomenon of surge in compressors and pumps. Typically, the model under study is a Helmholtz resonator and driver where the flow in the delivery duct to the resonator ...
Compressor Performance Modelling And Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 1987)
One of Du Pont's plants operates a 20,000 hp synchronous motor driven process air compressor consisting offour compression sections and three intercoolers (Figure 1). A six percent capacity increase from refitting the first ...
Revamping The Air Compressor In An Ammonia Plant.
(Texas A&M University. Turbomachinery Laboratories, 1987)
Revamping the compression equipment in an ammonia plant can help optimize plant output and improve overall efficiency. In this case, proper sizing of the revamp is important for optimum results.
The reformer air compressor ...
Stall, Stage Stall, and Surge
(Texas A&M University. Turbomachinery Laboratories, 1981)
An extensive introduction to stall, stage stall and surge is given with examples of the various stall phenomena including recirculation. Particular components including the inducer, impeller, vaneless diffuser, channel ...
Field Testing Of Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 1981)
Field testing of compressors may be carried out to monitor for performance shortfall in normal operation or to verify performance following an overhaul or revamp. Testing requires careful measurements of pressures, ...
A Practical Guide To In-Place Balancing
(Texas A&M University. Turbomachinery Laboratories, 1981)
Rotor unbalance remains one of the leading causes of deterioration and vibration of rotating machinery; but, if physical weight corrections can be made, many machines can be successfully balanced in-place with considerable ...
