About PSV capacity evaluation

[Jim111]

One question popped up, about heat exchanger with two tube( one for steam and one for ammonia liquid), between the two tubes is methonal. The RV of shell side is 6890 lb/hr( Methonal), the tubeside of ammonia is in liquid condition(-32 C@ 900 Kpa), flow rate is 399kg/hr). I just do not know how to check if the RV is good for pressure releaving when have tube rupture in ammonia tube.

Thank you for your time.

I'm not following what this heat exchanger looks like configuration wise, can you post a sketch?
