Dear Friends,
I have some questions about gas recovery line in reciprocating hydrogen compressors, We have 3 Double-acting compressors which in every stage, in the distance piece part, there is a connection called gas recovery. this connection is piped to atm or flare.
I want to know the application of gas recovery and the difference of this connection with vent connection. Moreover, I want to know the application of Nitrogen in distance piece.
I have attached a figure of distance piece connections.
Thank you for your time and consideration.
