You should check with your Insurance Underwriter to make sure that you are covered under these conditions. You can size a relief device set at 14.5 psig and protect the vessel. If you design your vessel for 14.5 psig, I believe you can use it as a non-pressure vessel.

Why do you want to use the MAWP of 65 psig instead of the 15 psig? If your state is a “stamp state” (requires that the pressure vessel carry an ASME stamp) then, you must abide by the ASME rules. I am not familiar with “SuperChems” and I don’t know how you set up your relief scenario, but you should be able to protect your vessel. You say that calculated relief valve size (fire case, two-phase flow, SuperChems modeling) was inflated to a point that it is not feasible”. I request the size because I find it had to believe that you can’t find a PSV to fit on the vessel. This may have changed recently, but I think the 15 psig design limit is correct. of capacity (I believe I remember this correctly) or more. ASME classified a pressure vessel as one that had a design pressure of 15 psig and 1 cu. You left out the size (capacity) of the vessel, the fluid involved, your calculations, the fill capacity, and the relief cases studied. I am sure I left out some necessary details so, please, if there are any other details you need, I will do my best to supply. 40psig higher than the design pressure) to determine the PRV size, will I run into an issue with having to categorize this vessel as a 'pressure vessel'. If I set my relief pressure to 15psig and use the MAWP (which is approx. Does the 'design pressure' calculated MAWP, 'relief pressure', 'operating pressure', or some other variable (or combination of) determine if the vessel is considered a 'pressure vessel'? When I did that though, my calculated relief valve size (fire case, two-phase flow, SuperChems modeling) was inflated to a point that it is not feasible. I would prefer that this vessel NOT be considered a 'pressure vessel' as I want to avoid the necessity of having an NB number, but I am a bit confused as to what defines a vessel as a 'pressure vessel'.įrom direction internally, I had initially set my design pressure at 15psig and set my relief device (PRV) to relieve at 15psig as well with the goal of avoiding the 'pressure vessel' designation. During packaging, the unit will operate at roughly 12-13 psig (fluid will be transferred to smaller containers). During blending, the unit will operate at atmospheric conditions (it will be vented).

I am working to purchase a portable (non DOT) 1250L nominal, 1430L total size vessel that will be used in various locations in my plant to blend chemicals (mostly flammable solvents) into and package from. That being said, I am hoping to find some clarification to an issue I encountered. First, let me say I am new to the forum (and to the Chemical Engineering discipline) and I have been impressed with the knowledge that can be gleamed from this site.
