.....currently the compressor in flash gas recycle unit are sized based on the flash gas from condensate stabilization trains. But the client thinks the condensate production would be much less than the design of 60000 BLPD. This means the quantity of the flash gas generation would also be...
Good day Folks,
Can anyone tell me the difference between Asymmetrical and symmetrical RMS fault current and how to determine its values for a ring main unit
My qusetion now is how does this frequency deviations affect the no of GTGs my client is telling me to use 3 + 1 philosophy as against the 2 + 1 philosophy due to frequecy deviations.
I have a 33mW Load and intend to drive it with 3 GTGs running and 1 on standby each rated 12.9 mW,i also have the option of running 2GTS with one on stanby each rated 19mW.
can any one explain to me what frequency deviation issues could arise with either of these options
I have a load of 32mW running on a GTG of 3 + 1 philosophy at 11kV i ran the motor starting analysis(ETAP) and because of the sizes of the flash gas compressors (about 2mW each) i placed all medium voltage motors on VFD. Butt after the analysis the compressor motor are all running but not at the...
But also i have run the system on on VFD even though the compressors are starting at 110% the compressors are not running on full load current ie cannot achieve max spin on if VFD is adjusted to 250% which is unconventional
I have a peak Load of about 33Mw(at 11kV) and wish to use 3 GTGs rated 12.9Mw with an alternator of 15Mw with 3+1 philosophy included these Loads are
XHP Flash gas Compressor-2Mw
HP Flash gasCompressor-2Mw
LP Flash gasCompressor-1Mw
Surge vessel Flash gas0.8mW
All on electric drives we have run...
