Dear All,
I intend to check capacities of installed relief valves at ammonia plant. The objective is to limit operation of plant load higher than the design relieving capacities of RVs as we are operating plant at load higher than the design. Since API-520 is for sizing the RVs, however in my case, I just only need to perform a capacity check,
So kindly suggest which standard or method should i follow. Also, do i need to consider different scenarios in this evaluation such as fire case or non fire case, block valve case etc.
Looking forward for your valuable comments.
