Bypass of Kickbacks
Bypass of Kickbacks
(OP)
I don't know if this is the right place to post a question with respect to the kickback lines of the centrifugal compressors.
Does any one can share his experience in an application where bypass lines are provided for min flow recycles (Kickbacks) of a big centrifugal compressor for some purposes?
The case I'm evaluating that a big compressor with kickbacks protecting refrigeration compressor (Ethylene Compressor).
Any experience is highly appreciated
Cheers

My question:
Is it possible to provide bypass of a kickback valve installed for a compresor?

i trust this helps . . .
there are other websites that may be helpful as well. use google and "centrifugal compressor surge control" for criteria.
good luck!

There is no need for bypass for large expensive valve and in clean service.
Therefore, if you got a problem in the valve, you will be forced to de-inventory the refrigeration system so you can work on the valve.
This is the reason why a bypass is highly recommended to avoid above bad situation.
Do you agree?

more thoughts to ponder . . .
first off, if problem with anti-surge valve exist, i recommend effort be focused on obtaining a valve suitable for the service and/or investigating the control system for the compressor. for normal operation, that anti-surge control valve should not be opening.
it seems that the centrifugal compressor anti-surge system (piping, valve, etc) should be installed between the compressor inlet/outlet valves. so de-inventoring the system will only be the compresor piping, drums, etc. which is not the entire refrigeration system.
hope this helps . . .
good luck!
