Jun 2 - Tehran, #Iran Large fire reported at the Tondguyan Oil Refinery in Tehran. The Director-General of Tehran's Crisis Office said an emergency liquefied gas line at the Tondguyan Refinery in Tehran has caught fire.

Reported to involve 18 oil storage tanks. https://english.alarabiya.net/News/middle-east/202...

In the video in the Instagram link ((McDermott1711's post), you can see that there was a partial failure allowing a cascade of ?? for an unknown period - certainly before the start of the video, prior to the complete ring failure. The containment was already saturated before the major release.

RE: Tehran Oil Refinery - Fire moment

The tank in the middle failed in ring tension. Not sure what it contained, but it ignited instantaneously.

The Iranians are having a bit of bad luck recently, the poor things.

RE: Tehran Oil Refinery - Fire moment

Is the movement caused by a camera on a mast, in the wind? I wrote a program about 30 years back to remove the motion so that the camera could be used for intrusion detection...

What was posted appears to be a handheld cellphone video taken of the closed-circuit security video playing back on a computer screen. If you watch, about halfway through the video the cellphone was moved back enough to see the edge of the monitor.

RE: Tehran Oil Refinery - Fire moment

The initial failure appears to be a seam splitting open between two rings of the tank. This probably weakened one of the rings which eventually ruptured. As to what caused the fire, we can only speculate but I would put my money on a ruptured conduit leading to some sort of electrical gear in the tank farm. Not sure what the protocol would be in a situation like this, but if I saw flammable liquids spilling, even into the containment area, the first thing I would consider would be to cut power to anything electrical near that containment area.

I only saw "whitish liquid". The "black" appears to be the color of the inside walls of the tank.

RE: Tehran Oil Refinery - Fire moment

how much of their capacity has that taken out?

RE: Tehran Oil Refinery - Fire moment

The only thing I understood in the video was “LPG”. It’d be great if someone could translate what is said in the YouTube video.

Good Luck,

RE: Tehran Oil Refinery - Fire moment

That bund looks pretty small but like most others it isn't built to handle a sudden catastrophic tank failure so that's why the spillage is so large.

Just as well it caught fire very rapidly. I wouldn't want it burning away under those LPG tanks. A BLEVE of those would be seen from space.

RE: Tehran Oil Refinery - Fire moment

Being the liquid was "whitish" and it ignited as quickly as it did, it was some sort of refined product, perhaps gasoline or jet-fuel.

Jet fuel isn't whitish its basically just diesel

RE: Tehran Oil Refinery - Fire moment

Maybe it was naphtha, which can be colorless. Note that Iran produces over 3,400 metric tons of naphtha per year.

I will make a wild guess here.
I think he is actually speaking very bad German, so you should talk to Lou Scannon.
He is saying something like this and now I will blame all the wrong words and spelling on the guy in the video.

In the second tank is the mechanical service distribution point for the LPG then something blablabla I cant hear/understand what he is saying and there is the pressure bar and main system, key.

A terrible fire in Tehran's refinery..a terrible explosion 💣💣💣💣

#Fire 🔥 breaks out at Tehran Oil #Refinery ( The fire erupted at the state-owned Tondgooyan #Petrochemical Co. to the south of Tehran)
A huge fire broke out at an oil refinery in the southern part of the Iranian capital
#Tehran on #Wednesday (2 June 2021)

According to local reports 18 storage tanks caught fire in Tehran Refinery fire, IRAN (2 June 2021) ، 11 people were injured, with four in hospitals.

This scene is due to the disintegration of the tank shell due to oxidation decay. It starts from one end of the Joint Weld.
None of the protective layers could prevent the massive leakage of hydrocarbon material from such an accident.

The problem of tank maintenance and non-compliance with welding standards over time and inspection and review according to the checklists of the mechanical unit , suspect non compliance with the MI( Mechanical Integrity ) element of
PSM.

RE: Tehran Oil Refinery - Fire moment

I reckon he is speaking Farsi.

They have loads of different lingos in the country so for most of the population they have to be able to communicate in Farsi but it may be their 3 or 4th lingo from birth.

It always a bit embarrassing for me hearing my fellow nationals going on about the accents and standard of English in these places. Most brits only speak one lingo English and for some of them I struggle with the accent and diction never mind a second language speaker which may actually be a 3rd to 6th in these sort of regions.

There is a a lot of Turkish lingo used and they mix and match some of them.

Politics aside I have always found the Irian people absolutely lovely, warm and helpful. Love their food.

RE: Tehran Oil Refinery - Fire moment

Well I will retract my former statment and say, he is speaking German.
The three first worlds it's quit clear, I am not good at German refinery terminologi but I am sure.
He is explaining to someone where the different control and monitoring devices are on that second tank which he is pointing at with the mouse pointer.

Second that. I worked on a project with someone from Iran who hit me with this from Marjane Satrapi

RE: Tehran Oil Refinery - Fire moment

That's just what there instruction manuals are in and as there are no local words for the equipment they have taken in the German into the local lingo.

RE: Tehran Oil Refinery - Fire moment

Yes I was actually trying to find a manual or a better technical translation site, google translate does not cut it here.
Just to confirm my statment that he speaks German.

Chinese is even more interesting... they may have 200 different dialects where one person cannot talk to another... but, they have the same written language. I can write a note to Freddie, even if I cannot talk to him.

RE: Tehran Oil Refinery - Fire moment

The Persian thing is a huge political fight in the region it has ramifications I don't really understand. But it also involves clashes between various flavours of Islam and which one has supremacy.

It reminds me to be honest of the subtle nonsense that goes on in Scotland between the Protestants and the Catholics and as an east coaster Aberdonian I don't really understand that, I don't have much chance with Islam either.

Yeah, pretty bad, that; I was around 10 or 11 when I visited my mom at the bank in Chinatown and this old lady came in speaking a dialect that baffled everyone but me, since it was the same dialect my babysitter spoke. And the dialect is from the same province where Cantonese is common: https://en.wikipedia.org/wiki/Taishan,_Guangdong

RE: Tehran Oil Refinery - Fire moment

We did have a Persien technical director not sure it was any different then having a Swedish one.
We have a lot of different people with different nationalities at the factory in most cases it's no different from Swedes.
The only ones I can remember that stood out a bit was actually French, we hade this division manager, he came visiting every month, threatening people that he would sack them, which isn't easy in Sweden if not impossible.
And then this Frenchman in the produktion, he got so angry with me once that his colleagues had to hold him so he wouldn't jump on me.
He hade manipulated the security system with some mechanical contraption, so I toke it away and threw it in the
scrap press.
I told them a hundred times it wasn't ok, they always managed to hide it from me, but not that time.

That's the whole daft thing its all the same bloody GOD or big man as us jocks like to call him.

There is an Irish Catholic priest in my local and we have had a few discussions about this stupidity.

I spent my youth a few times in a PIG in NI and like most solders of the period felt like we were piggy in the middle and actually supported a united Ireland. Still do to this day but would never wish those animals in NI on the southern Irish.

Sean has some great dits about when he was in Manchester and shared the chaplaincy in the Cat A prison with an ex UK SAS padre. Who in his first week went in solo with some gang land nutter who was in for life who thought it was a good idea to take him out.... He carried the same bible with blood stains on it for his two years there, and nobody touched him again. Even the prison officers were surprised at the level of violence that was dealt out in such short time period by one man with no broken bones. He did say though to the guy "I have killed more than you and buried more than you and I am not talking about the ones they know about. Lord please forgive me for educating this young man". Any thing kicking off afterwards and he was there, he would just go in solo with his book and everyone calmed down. Sean said he couldn't do it.

LI I agree but if you have ever met the same as us Iranians its pretty horrendous for them. Haven't been there for years but will always remember my time there.

Lovely people.

Well the tank was motor welded where it broke, do not know how long ago.
LittleInch you must know what kind of instruments there are on those LPG containers?

RE: Tehran Oil Refinery - Fire moment

Must have been very poor welding, as the force on the wall of a circular tank is small in that direction.

RE: Tehran Oil Refinery - Fire moment

I think it was probably lots of corrosion rather than poor welding.

LPG domes like that just have pressure and temperature usually. Level they probably just do by pressure/weight.

They should be designed for a fire case but there may be distribution valves under the tanks which are more exposed.

They may not have considered that a wave of burning liquid would arrive and sit under the tank. Anyway it clearly didn't BLEVE otherwise we would have seen it by now.

RE: Tehran Oil Refinery - Fire moment

Poor welding can lead to corrosion faster then a good weld, much faster.
BLEVE ?

RE: Tehran Oil Refinery - Fire moment

Confused messages coming from Tehran, but lots of mentions of an LPG leak/ due before the main fire. No mention though that a tank failed.

It may have been a large slops tank so maybe that was water coming out then when it failed the oil above the water layer got exposed.

The tank may have been exposed to a jet fire? Hence weakened and started leaking.

Since when has oil waste been refueled?

Why should the storage of this oil waste be close to the city and the people when it is so dangerous?

Sounds like someone who's never seen the inside of an oil refinery....

The refinery has been there 55 years - it's very likely the city has grown to encompass the refinery, not the other way around.

RE: Tehran Oil Refinery - Fire moment

(OP)
By looking at this picture, it seems that they didn't consider a dyke for the tanks and I recon the tanks was used primarily for water storage (and perhaps this is the reason we don't see a fire protection acting automatically for them).
I've heard that (due to sanctions) Iran can no longer sell its condensates (from natural gas refineries) and tried to store them everywhere possible and by reaching the end of storage capacity, the process of natural gas production is disturbed. And I guess this is why we see scheduled power outage in the country.

But, the photo does show a wall around these tanks, which is why the fire retardant is all contained in the vicinity?

Is the height enough?

RE: Tehran Oil Refinery - Fire moment

I work in a hydrocarbon storage company. Due to the characteristics of the tank (floating roof tank) it must store gasoline or something similar with a low flash point.
The collapse of the shell is spectacular and the weld must be very weak for it to open like this. That tank is not a water or LPG tank.

It looks like the product is coming out of the envelope before the collapse and the explosion. Product leakage generates an explosive atmosphere.

After detecting the initial leak, they had to trigger the fire system to fill the area with foam. In addition to removing the electrical power from the area.

RE: Tehran Oil Refinery - Fire moment

Mcdermott,

The bunds are typically sized for the largest tank and to contain its volume +10%. The safest way is for each tank to have its own bund, but that takes up a LOT of space so usually you find multiple tanks within a single bund so long as it is all the same product. Especially for tanks built in 1960's.

No bund wall I am aware of considers tank failure like we saw where you get a tidal wave of liquid.

From the garbled information we have I think this tank was possibly being used as a giant water separator, hence the flammable bit was higher than the leak area and maybe having water in a tank not designed for it has caused corrosion in a seam weld. There was also mention of an earlier LPG fire which may have stressed that tank - who knows?? Also the tank may have been repurposed over time as the reports mention this being a "slops" tank.

Remember - More details = better answers
