I have centrifugal compressor. For which i want to know whether compresdor will go in surge even if surge valve is open in following cinditions during discharge valve closure or compressor trip or compressor trip or compressor countdown or compressor suction valve closure ?
The query isn't so clear...
Anyway, if antisurge valve is open, compressor won't go in surge following to above mentioned conditions provided that the valve had been properly sized...

I wish to know under which conditions compressor will go into surge ? As for most of the conditions antisurge valve will take care
When the ASV, in any reason, won't be open while needed to be open and also when it's undersized...

I want to know whether compressor will go in surge even if surge valve is sized properly and it is opened in 1 sec when operating point reaches backup line on flow vs head curve. Also i wish to know whether compressor will go in surge if emergency shutdown is done or normal stop of compressor or compressor trip or compressor countdown or suction valve is closed. Request your advice?

Dear
It is posssible if your anti surge valve or antisurge line size (i. e the flow at anitisurge condition is higher than choke flow in the anti surge line) is inadequatly sized.
