Hi everyone,
I'm checking the feasibility of adding to more user to our hot oil system (heat duty, volume...), the main problem to connect those to heat exchanger is that theirs design pressure (12 barg) is lower than the actual discharge pressure of the hot oil recirculating pump (13 barg).
My question :
1. is it possible to install any means (pressure valve) to drop the pressure just upstream the connection line feeding those two exchangers and keep the actual network working as it is?
2. what king of protection is to be installed to avoid overpressurising those two exchanger?
Thanks in advance
