Operation Analysis of Centrifugal Compressor Driven by Gas Turbine in the Purified Gas Transmission Station of CNPC International(Turkmenistan)

CNPC International(Turkmenistan) purified gas transmission station,located on the right bank of Amudarya in Turkmenistan,is the natural gas export transfer station,which produces 13×109 m3 of natural gas every year.In the station,the centrifugal compressor driven by gas turbine,which can deal with 5×109 m3/a of natural gas,is a core equipment that mainly undertakes to pressurize and measure upstream purified natural gas and transport the gas to Central Asian natural gas pipeline.According to the unit design,operation,faults,etc.,the technical performance and features of the centrifugal compressor driven by gas turbine in actual operation are summarized and analyzed.Reasonable operation schedule is put forward and implemented which has obtained phasic achivements.
