My Stepdad worked at The refinery for over 15 years.

My stepdad grew up in town there and refinery life is in the blood of all those people. It could have been anyone, every man and woman rotates through all the jobs there at the refinery. My stepdad would have been out there the next week. Working on those same tanks. It was a really hard time for all of us, for my mom especially. My stepdad and several others retired over the next few months.

That's always one of the hardest parts of watching these videos. As a chemist I find them fascinating and wish there were even more videos, until I think about the cost of that. I really do wish they would stop making videos due to lack of source content. Unfortunately that seems unlikely. I just wanted to thank you for giving me a perspective (and reminder) on these videos that is easily forgotten when you are not directly involved. Hope all is well for you now and you are having a good day!

Actually, some of these videos would be useful for science classes in school: Dust explosions are something few even would think possible -- I'd have never thought flour or confectioner's sugar could explode.

@@RobGcraft confectioner's sugar explodes because it's so finely granulated. this gives it a very high surface area to volume ratio, which means it combusts more violently and rapidly. regular granulated sugar is equally flammable, but neither is all that flammable. the issue with combustible dust is that there can be huge amounts of it in a tight space where it's mixed with the air. so rather than just a pile of sugar catching fire, you get a fire that spreads through the air, and it spreads and expands very rapidly because the dust is so fine. the finer the dust, the faster it burns, and the faster it burns, the faster the combustion byproducts expand. which is essentially an explosion. there is some minutiae about what really defines an explosion, there's a strict line between detonation and deflagration, but in practice they can seem like the same thing, because a fireball doesn't need a massive shockwave to do extreme damage. a giant, rapidly expanding fireball below the speed of sound is potentially more dangerous than a grenade that breaks the sound barrier. anyway that's the deal with dust. if you have a flammable material, and you're gonna be cutting it up into super tiny particles that can float in the air in high concentrations, then you need to take a lot of precautions to prevent it from combusting, or you need to clean it up. both from the air and from surfaces.

Very informative! Thank you for your animations and narrative.

I was friends with a gentleman in my church in Burlington, WA that had a coworker switch shifts with him so he could be with his family the next day. He didn't make it and my friend was super devastating but didn't take life for granted after that!

As a mechanical engineer graduate proper material selection is of the essence when designing heat exchangers for certain chemicals as well as developing maintenance routines. Copper, SS, or aluminum for water to water, SS for naphtha, and more. Even a steam heat exchanger explosion can cause life threatening burns, blast injuries, or instant deaths.

I learn more about physics and chemistry and safety here than I did at school

Your videos are fantastic. But what a way to go......absolutely horrific. Thank you for sharing!

I've become hooked on this channel. The lack of maintenance in so many companies, this one included, totally shock 😲 me to the core. Want the fact that the CSB can't just make the changes to the law, that they can only make suggestions is disgusting. Petroleum companies have no intention of stopping these kinds of tragedies, IMHO.

The first time I watched this video, my cat was sitting in my lap. At some point she began watching the CGI people working as the Sun set and when the unit exploded she visibly startled.

Poor workers. Dying in a fire like that is brutal.

I hate it when people get hurt or die at work, because somebody decided not to replace old equipment, or do the correct maintenance.

Sad loss of life. Condolences to the families of the seven workers. Hope for a full recovery to the four injured men. This information must be shown to as many people in the industry as possible world wide, to increase safety awareness. Every accident must be learned from so improvements can be implemented, especially if there was a loss of life. Your animation quality is very very good, it clearly explains what happened.

RIP to the workers that died. That’s pretty brutal and sad.

What is more interesting to me here is to know that " At high temperature the hydrogen reacts with carbon to form methane (CH4) gas entrapped inside the shell wall and create stress enough to cause the shell failure"..... That is more valuable knowledge ... I think....failure of internal coating of the shell have occurred first which allowed the hydrogen to reach to carbon and reacts. It is really beneficial to know how much time this reaction had taken before it caused such failure in 1" thick shell.... regular inspection of these exchangers is expected to detect such failures. I think installing small by pass line for isolation valves to slowly heat up the heat exchangers before opening the main isolation valves may prevent normal observed leakages during start ups.

One would think there would have been something to look into having a nearly 40 year old piece of machinery used at the refinery replaced as soon as possible.

I wonder how many years these heat exchangers were rated for, and how many years past due for replacement these ones were...

@danielebrparish4271

There was one video that showed a disaster caused by a software upgrade. The new software inadvertently omitted the replacement dates for a piece of equipment. It was supposed to be replaced every 6 months, was missed and wasn't replaced until it blew up 3 years later.

Letting a critical high pressure system go uninspected for 40 years until the inevitable finally occurs sounds like negligence to me.

Cavalier acceptance of suboptimal functioning old equipment under pressure. Amazing. No not really. RIP men.

@emanwe01

2 жыл бұрын

If by high pressure you mean high temperature (since both hot and cold sides of the exchanger were at high pressure), I'm guessing it was because of the fouling. It's easier and faster to clean out the insides of all of those tubes than to clean the outside of the tube bundle plus the inside of the outer shell. For the former, you can just use a pressure washer. The workers in the video actually do this. For the latter, you have to remove the entire tube bundle from the exchanger. A lot more involved and time consuming.
