Hello everybody,
I work on the anti surge protection of a gas centrifugal compressor, where an addionnal check valve is installed directy at the compressor discharge, upstream the recycle loop. (There is also a second check valve dowstream the recycle loop as a typical anti surge configuration).
On my mind it is not a good idea to add a check valve between the compressor discharge and the recycle loop because in case of surge, the check valve will close and avoid an efficient and quick response of the anti surge system. I have already experienced this phenomenon.
What do you think? Could you share your experience?
Thank you
