You wouldn't believe how many times things go sideways and you don't hear about it or find out weeks or months after. They have an emergency alarm system they test on the first Wednesday of every month, and not ONCE during my 30 years living here, when things went wrong did that alarm ever sound. Scariest day ever was when the pacific grid shut down and the entire refinery was pouring off black smoke and every one of their burnoff stacks were in full bloom. One night they were burning off a LOT from their largest stack, a flume that had to be at least 100 ft high, and I FELT the heat from it at what I estimate at about a quarter mile away.

@@MXedos Depends on the pressure parameters in other parts of the plant and the shut down procedures and safety valve settings that might have saved the situation but also might have not. You need to go deeper into the shutdown procedures and settings to get that information. It might have been possible to find the leaking heat exchanger earlier by some some sensors in the water side or by finding changes in distillation results in laboratory - who knows - you just need more knowledge of the details. Actually they plan maintenance shutdowns to inspect all the parts and should have found the problem with the valve for the catalyst balls earlier. Sometimes there are factors you cant foresee. I have seen holes in pipelines lying in the desert 5m deep. That place the water table was only 3 meters deep and the coating of the pipe had a damage - maybe from long time ago. Another pipeline started to show one leak after another since one company pumped frequently salty water in because they were stupid, they put in corrosion inhibitor for H2S corrosion but nothing in their water phase at the desalters. When the pipeline was out of operation for some weeks the water collecting in some low sacks eat through the wall. When starting again it was a sieve.

I used to build scaffold and I've been in every bit of that system. It's fascinating to see all these things firsthand. The animation brings it all together. Steel mills are also amazing

When they broke open the flange to install the blind, the workers were met with flowing steam. This should tell them that the catalyst seal was not intact and that hydrocarbons from the distillation train could flow back. They probably figured this out but assumed that the hydrocarbon side was completely purged of flammable materials so they lowered the steam in an attempt to install the blind. The bad luck of having a leaking heat exchanger blew away all the assumptions. This is how accidents happen.

@mikec8679

No hes right this is how accidents happen. They used a shit variance that didnt allow for zero energy and proper isolation in order to save time and money. You can talk all you want about systems but this is exactly why you blind and isolate and verify zero energy. I never work inside of any vessel unless its blinded at the first flange and every flange off the vessel and i only install those blinds after a thorough loto and proven zero energy is in place. Even after that precautions should be taken. Its so easy to miss these things and thats why you need qualified people working on your equipment and redundant checks are put in place. Ive seen people mistake orfice plates for blinds or break open the wrong side of a closed valve because they didnt double check or verify. That was a 2012 variance and should have been scrapped and a newer better procedure developed. Instead they cheaped out and boom. RIP.

Man, the CSB really takes pride in producing high quality illustrations and narrations.

I just retired from working in a chemical plant for 38 years and worked in a coal fired coal plant before that for 2 more years. There are two videos I just watched where an explosion was caused by the slide gates failing thus causing the catalyst shield to lose it's level via the leakage through the damaged slide gates. if there was an alarm on the catalyst level in each of these instances it could have sounded when the catalyst level in the vessel got to too low of a level warning the operators that the catalyst was escaping through the slide gate. Also having pressure transmitters on the hydrocarbon cracker and one on the vessel the steam was going into would allow the operators to see if the steam pressure was higher than the process pressure and keeping a seal on backflow of the hydro carbons. The slide gates needed to also be on a regular checkup and replacement schedule due to them failing in both these incidents. Seems like this type stuff was overlooked or the operators ignored certain alarms.

If you watch a number of CSB videos you'll notice a definite trend of the same mistakes being made over and over again.

I worked in a chemical facility making automotive paint. Every step of every task was dissected, documented, and theoretically, even with an an equipment failure, a safety issue should never arise. But employees were pressured, and rewarded for, production. Employees who took dangerous shortcuts completed tasks quicker, and their speed soon became the standard. Production trump's safety every time. We had enough solvents in dozens of 10,000 gallon tanks to straighten the river bend we were located on. Even though we lived safety, and management preached it religeously, they turned a blind eye to short cuts employees are pressured to make, until something goes wrong.

"That'll do and lets hope for the best" sorta mentality that major companies have, or so it seems to me. Risk reduction is very expensive and companies have mandates to only increase productivity and efficiency, and thereby gain more profits. Increasing profits by slacking and going cheap on safety systems, apparently, is an acceptable risk in the CFO's cost/benefit calculations. After all, as far as corporate is concerned, nobody they (in-charge executives/corporate) care about is at risk, so what?

Robert Mintun The animation gives the impression that the flue-gas system (FGS) is dedicated solely to the run-off gasses from the fluid catalytic cracking (FCC) unit; this might not be the case, as flue-gas from other areas of the plant might be treated there as well. What this means is that shutting down the FGS doesn't just stop the FCC, but also other areas of the refinery. Shutting things down means they're no longer making money, but instead costs money. You can probably figure out how the guys up top feel about that.

LOL - the sound bytes are ADORABLE! I especially love the bubbling ones.

I love the little sound effects they add for the coking of the catalyst molecules at 1:15. They did this in a few other animations I have seen from CSB too :)

Great visuals! The slide valves on the Cat Unit I worked on were never tight shut off, big gate valves were the true isolation points. A flow reversal might have been prevented by tripping the air blower and slumping the catalyst bed, feed would also be tripped and diverted. Steam would be introduced to keep the catalyst bed fluidized and positive pressure to keep the fractionator from reverse flow. We had a CO dumpstack that prevents sending hydrocarbon saturated catalyst to the precipatators and the CO Furnaces. The Benicia Refinery has an Exxon designed FCCU now owned by Valero Energy. Variants to standard operating guides are a form of risk management. Most times they worked, but every now and then they would bite you.

These videos are truly Amazing. Not only do they explain the accident in a easy to understand format. But they also explain the complex and hidden nature of these refineries and how they work.

The well maintained refineries run and take time to shut down for maintenance and thorough inspection, and the others blow up and go back online after repairing what blew up till next time.

Slide valves have blown up other refineries...just change them out every year.

Cost cut for sure. It's an old fight of departments: maintenance vs manager. Manager says that the time needed to do the maintenance compromises profit. Maintenance says that bad things could happen if stuff don't get fixed. Who you think is the boss?

The slide valves are massive. Just one can weigh several tons. They're welded into a huge pipe. It can take a week of 2 shifts to change one out. Millions of dollars and the entire unit will be shut down.

Nice to know that my car has more pressure and temperature sensor than a chemical reactor 😄

My grandma from Dad's side lived across from rampart hospital depicted on Emergency, the adam-12 conjoined twin drama back in early to mid 70's where it actually lived? Torrance, California! Passed that refinery every week. Refinery on the left, Goodyear blimp on the right.

The effort in making these 3D models and animations is remarkable...

question: why does the ESP remain energized in safe park? Also why wasn't it turned off when they evacuated

Incredible.

No problem with the simulators. Instrumentation and operation errors are the problem.

I grew up in Houston. Fortunately on the west side of town. That was bad enough with all of their air pollution.

Probably the best animation on youtube to this day.

This is seriously amazing, great animation.

Never, ever let the reactor or regenerator go empty! You can use reactor/regenerator pressure if the slide valves pass.

Cute! They know that even with all the treatments and alloy coatings they use in the pipework, vessels, and valves, corrosion and sediment build-up is going to still occur in just a matter of years, yet no one inspects, nor replaces anything until something goes critical or explodes...

Corporations serve their greedy shareholders. They have no real interest in public safety. Their insurance company pays off the damages and they go back to making money for shareholders ASAP. Insurance costs are tax deductable. Any fines, if given at all, are relatively small potatoes. Why should they worry?

Excellent animation. Thank you!

I am grateful for the explosion animation at the end 🙏

I remember I was in class at elco when this happened... was intense.

Lets just reduce the steam pressure, the only thing preventing a flow-back of gases, to do our maintenance.

I'm binge watching these. Very informative and educational videos.

I’m a truck driver, I drive past this refinery a couple weeks ago and had a strong urge to hurry up and get away from it as fast as I can, then this pops up in my recommendations lol

So, Let me get this straight, They attempted to linebreak on a unit that hadnt been shut down properly, not isolated correctly, and had live steam in? Plus failure to inspect/test valves that had been in service for 7 years? I would honestly expect better from Exxonmobil.

Man, I worked in refineries most of my life and you've got to keep your equipment maintained, most important thing. This could have all been prevented by regular inspection and replacement of a simpe slide valve. This would probably be about 1 to 2 weeks of downtime for the plant but look at the results of what the prevention would be. Greedy Executives pocketing the money instead of reinvesting into plant maintenance I'll guarantee you that's the issue.

This was VERY well explained in great detail, I'm also glad nobody got injured.

Amazing animations, narration, and descriptions. Subscribed.

Excellent investigative work , keep up the good work

It is truly astounding how the fossil fuel industry, with all their billions in profit, won't invest enough capital into MAINTAINING their facilities!!! So many of these videos deal with facilities that are so outdated and in such disrepair that the inevitable result is a preventable catastrophic event!

@xthomasbhx

The facilities are good enough. If they were to "modernize" the place it would cost a lot of money, so they don't do it. The way the facility is designed is still good enough today. Im sure if they were to "modernize" there facility the company would still be okay, but there might be a small cut on company executive salaries, which im sure they will live, but they wont do it. Edit: the main reason why this happened was not because of the way the facility was designed. But of corporate greed: CEO and executives pushing managers and workers to work harder (e.g., me executive want my numbers higher), ignore facility maintenance (its cheaper but not safe, hence this event and video).

Great explanations and animations in your videos!

Never got to work directly on the cat unit controls but worked in the surrounding units . Was always curious bout the components this video really a good illustration.

I live five minutes from this

At least I am watching something productive at 1:30 AM I liked this narrative!

CSB videos are used for Process Safety training across the country. As a power plant worker, I have seen my share of these videos which when broken down show even though well thought out procedures exist in every industry, its never just one thing that cause these catastrophes. That's why we constantly train on PHA (process hazard analysis) & LOPA (layers of protection) to mitigate these accidents

worked at a fccu. there was a level indicator between reactor and regenerator so you should see the level going down if the catalyst barrier cant be maintained

"Its 3 in the morning, you should really go to sleep!" Me: hydrogen dioxide...interresting

Why the hell was ESP running when rest of the unit was stopped
