LPG Vessel Explosion Impact on Boundary Wall

LPG Vessel Explosion Impact on Boundary Wall

LPG Vessel Explosion Impact on Boundary Wall

(OP)
Hi Experts,

I am currently analysing a scenario involving two premises, one housing an LPG (liquefied petroleum gas) vessel and the other containing a fuel tank, with a boundary wall separating them. In this scenario, I am considering the possibility of an explosion of the LPG vessel, resulting in the vessel's dish striking the wall.

I am seeking guidance on how to assess whether a typical masonry wall is capable of withstanding the impact of the vessel's dish in such an event. Are there any relevant case studies or references available for a similar scenario that could provide insight into the structural integrity requirements?

Thank you for your expertise and assistance in this matter.

RE: LPG Vessel Explosion Impact on Boundary Wall

How exactly is this LPG vessel / tank going to "explode"?

If you're talking failure of the vessel due to an external fire, look up BLEVE.... https://en.wikipedia.org/wiki/Boiling_liquid_expan...

You're going to need something more than a masonry wall, more like a 250mm thick reinforced concrete wall. It won't make much difference though when the fireball fries everything.

I would seriously question whether this is
A A credible event
B An event which you can actually reasonably protect your second fuel tank
C Something that would make any difference whatsoever to the final outcome.

Erecting a wall to prevent fire or leak from the fuel tank not affecting the LPG tank or vice versa in terms of a jet fire from the LPG tank ( more likely) might be good, but a simple block wall should provide sufficient time to either evacuate or deal with the fire.

A rocket attack might do it.

Put them in a dike, direct explosive overpressures upward.

Masonry will not work.
Reinforced concrete walls 2 ft thick might stand some chance if they are not too high.

RE: LPG Vessel Explosion Impact on Boundary Wall

The probability of an LPG vessel failure resulting in the complete unzipping of a shell end is going to be so low as to be negligible and hence whilst it might come up in a HAZID, really needs to be consigned to the not credible zone IMHO.

Protect both tanks from pool fires or jet fires by all means, but not this scenario.

RE: LPG Vessel Explosion Impact on Boundary Wall

About 40 years back I did an investigation about a propane tank explosion and the damage to a curtain wall... most of the damage was caused by the reflected 'vacuum', which had a greater impact on the connections to the aluminum extrusions.

RE: LPG Vessel Explosion Impact on Boundary Wall

How big is this LPG vessel as well?
A domestic / small industrial size or something much bigger?

Is this one premises or two adjacent properties?

Biggest issue with LPG is a reasonable sized leak from pipe work connections creating a carpet of very cold LPG drifting along the ground until it finds an ignition source....

Is reflected vacuum the implosion after the explosion occurs?
