Good morning all,
I have a doubt in selection of scenarios for sizing PSV.
There is diesel storage system, which consists of a diesel storage tank, diesel pump and fuelling system. The diesel pumps transfer diesel from storage tank to fuelling station. Two diesel distribution filters (1W+1S) with a PSV in each filter, are placed at the pump discharge line. Please refer attached process flow diagram.
For sizing PSV in the filter, Do I need to consider blocked in thermal expansion case or fire case? or both?
Please clarify my doubt.
Thanks in advance
Regards
S Manikandan
