Modernization of Steam Turbine Diaphragms for the Saudi Aramco Gas Plants
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The critical components of the Saudi Aramco Uthmaniyah and Shedgum gas plants are eight trains of turbomachinery, 4 trains per plant. Each train consists of a steam turbine and a centrifugal compressor. At the time of their ...
OPERATION OF CENTRIFUGAL COMPRESSORS IN CHOKE CONDITIONS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
Centrifugal compressors are at times required to operate in or
near the choke region. Various limits of the degree of allowable
operation in choke have been established. Based on test data
and numerical data, the behavior ...
