Ahh, neat! You even used that technique where you turn a negative into a positive. So "Thanks for understanding" instead of "Sorry for the inconvenience". Just kidding, i enjoyed the video.
These animations are excellent and very instructive. I work as a training standards manager and safety investigator in the transportation industry and being able to show detailed visuals of hazardous situations such as this is a hugely helpful communication tool. Out of interest, what tools do you use to creat the animations?
Some times bosses tell their employess to do unsafe things or they will get fired. Most of the time its because they are too cheap to buy the right parts or pay the worker for the time it takes to do it properly. I have been in this situation many times and if you cant walk off the job because you have a family to feed its not always easy to tell your boss " No Im going to do it the safe way and I expect you to buy the approved equipment to do it that way"
That arms massive punching power must have crushed his bones even the mere sound of air pressure gushing out should have scared him away unless of course some ill conceived jack ass supervisor instructed him to fix it.
Great Post. I have seen guys get hurt while purging air from a hopper scale which contained 1/8inch lime granuals. They shot out like bullets right through the clothing and into the skin and it began to burn them, Lime reacts with moisture. Proper purging procedure was in place, This was operator error. The operator was 100% blinded at the age of 33. For anyone in the idustrial field, Take Caution, Go home at the end of your shift, Not to the morgue.
I can bet if he saw the hazard and refuse to work without an engineered solution he would be no hero to the employer, though he remain alive. This is happening to workers everywhere - near misses; because employers want the go forward mentality in their sheep.
If I've learned anything, a lot of these hack work half rigged solutions come from men who think that their improvised fixes make them smarter than the engineers. Some people take such pride in their rigging ability that they don't want those "stupid" engineers and their instructions, and WANT to go it alone. Call it pride, call it people enjoying part of their job, but far too many people who work with their hands desire to find their own "clever" ways of fixing things, even if the proper methods and materials are sometimes available. Likely, if this guy didn't get killed, he'd be bragging about it. Its the kind of thing these kinda guys do.
kingduckford - I'm an aircraft structures mechanic. We are never allowed to improvise anything without an engineer's going through CAD and designing a modification. Often the solution must be FAA approved. However, I've seen time and again mechanics, myself included, think up the quick-fix solutions to problems incurred during aircraft structures work, especially when doing modifications. Often a part won't fit, somethings in the way, or a Hi-Lok or bolt will work better than a rivet. If an aircraft mechanic goes it on his/her own, the work will not be approved by the inspector, a job will usually be lost, and the mechanic could face FAA action including license suspension or revocation, lawsuits and criminal charges, etc... Not to mention that the "fix" could fail and hundreds of lives could be lost if the airplane crashes. Fortunately this is a highly-regulated industry. That said, often engineers will submit to mechanics ideas for a fix or work-around because we are the ones doing the hands-on work. We see and experience things the engineer does not. Some aircraft modification places I've worked had a daily meeting where an engineer or two comes to the airplane daily to see the problems encountered. Many times a mechanic's "fix" will be taken seriously, but engineering still always runs it through CAD to assure it's a workable & safe solution. So, while I don't think were "smarter than engineers" or have the capabilities they possess, both parties can and do work hand-in-hand to get the job done.
You'd think that it would be MANDATORY, for a tank that is EXPECTED to be vented every time it is relocated, that the vent be upward, from a valve on top of the tank.
quaztron but do they ever need these queens where they are covered by something? ? i think they should put a pressure reducer on the venting lower it down to a safer #.. or maybe have various vents instead of that 1, 3" line maybe a tee with 4, 2" lines. .??
A few years back there was an incident in the gas fields where I worked. Well, someone cross-threaded one of the ball valves along a high pressure line and when the psi hit, it blew the thing off. A nearby worker was hit by the flying valve. He lived, but it shattered his left hip.
Yes, but operational considerations are often not part of the engineering design of the product. I see this in software all the time, when applications are designed and written with no thought given to how they will be operated and supported on day 2, so operators need to come up with "creative" solutions to make their lives easier. Sad to see this is also the standard practice in the physical world.
Yes and no, for safety the chimney is much better, with out the chminey they vented with the valve that they used for filling and emptying to, so no extra venting valve are required.
Many times a worker will knowingly ignore the proper protocols in order to either save time or because its plain easier . I can understand that this man had no idea that the shear force from pressure would unthread that fitting. I'm a firm believer that equipment should be manufactured with safeguards in place that prevent unsafe practices.
there is no perfect way to manufacture everything to prevent all accidents. things are already made to mitigate risks but there will always be situations that have not been thought of
The one time I was told to help move around 1/2-1 ton stoplight poles. Very dangerous work, especially when the boom is swinging around and you're still grabbed onto it. After the first time, I said to my co workers while the bosses were around "I dont get paid hazard pay and I dont even have insurance. Its triple pay for hazard pay, and they're too cheap to give it to us." So, they got the other guys who did get appropriately paid to do it. Just open your mouth sometimes, it could save your life.
Sad story, but the real criticism needs to be aimed at the owner and then whoever designed the outlets on the side like that. Even if the worker did the job as suggested in the manual, that would involve moving around huge tanks, and it still blasts the gas at ground level where humans and animals walk.. Ridiculous and dangerous design. Most venting and exhaust systems go straight up in the air for a reason. Its easily blown away by the wind, and theres no people up there.
I totally agree. As I started this video, I expected the worker to die from asphyxiation. That assumption alone should have come to mind to manufacturing engineers, and given their knowledge about the extreme pressures involved, no human should have been put in proximity to that kind of power. Total engineering and management failure. As paying customers and decision makers, management should have sought better designs or forced for them to happen through industry safety groups.
Travis Ryno it's the workers dying from these pieces of equipment that come from engineers who say they know better..it's the workers who take the sh*t end of the scenario. That's why a finger needs to be pointed. Engineers are supposed to know better...Have you ever worked in the oilfield ? Tell your boss you aren't doing something and they'll find someone else. Report it and you'll be annexed. Not saying it's right, but it's what happens. Welcome to life, the engineers should have known better..the workers make far less and are held accountable at every corner. For engineers, it's back to the drawing board.
I have worked at numerous manufacturing facilities and have seen the resulting injuries of numerous accident where workers were seriously injured and, it tow cases, killed. In every one of them, the cause has always been the same...failure to follow proper safety procedures. You can always make something safe, but you cannot make it idiot proof.
Somewhat like 'billions of dollars', the power of explosive forces can be hard to comprehend for the everyday worker. Thank you , Work Safe BC, for making these videos public on TH-cam!
This was one of the scenarios that crossed my mind in just few seconds before the video revealed the horrible truth. One must always consider every possibility including the mechanical aspects of something especially with that much force be exerted.
In Alberta, we have the right to refuse to go do a specific job if we say, it is unsafe. More places should have that same right so people can go home to their families,
That was the hardest punch he ever took, did more than knock the breath out of him, it knocked the life out of him literally. He was lucky the first time but luck has a tendency to run out and his certainly did. RIP
This guy did not clearly understand the magnitude of the pressure that comes out and what it could do. Thats why the procedure calls for 300 feet of clearance. I use to charge and discharge Co2 bottles. These were very small compared to a truck, however one day while discharge a 25 man life raft bottle the the hole top valve can completely off. Thank god all safety procedures were followed and we only lost 7 roof tiles 17 feet above the bench. The roof tiles completely discenagraded, it look as if it snowed in the Co2 room. Never improvise when working with high pressure gasess.
I saw this coming. When I saw the pipe attachment, I'm thinking , that thing will spin of from the thrust. And that's what happened? Creeps me out that someone thought that would work.
@HelloHansSolo Probably a company name. Why can't venting be done using a remote solenoid? the oil companies have used that to regulate pipelines with successes for years
was it necessary to go to full pressure asap while venting the queens? I would have turned the valve SLOWLY and made sure I was out of the way of any possible problem. Seems like a lot of pressure to be allowed to vent at 100% asap.
They probably did open slowly because whipping open the valve would be a major blast. I do agree though they shouldn't have been standing right beside it. The sound coming from it would have been loud as hell.
2000 -3000 psi is no joke!!! There should be a regulator on those valves too!!!! Hvac nitrogen tanks use regulators too! Slowly dial up pressure for leak test & drain clog clearance!? Just a valve is not a well controlled set up!? I'm not a trucker or fool with carbon dioxide & I know better than to let employees feel safe with no regulators on that!? Smh.... No wonder I can't find work!? I have too much common sense?! Bosses fire me when I question their motives?! Had one lay me off after I told him they were using hydraulic hoses for refrigeratant lines Instead of braided hvac hoses!!! It's ok tho.... next person if I work again will be blessed to have a worker with common sense(goes a long way!!!)
@@leighcurran3423 wow, dude fire you for pointing that flaw out? In the long run, will see who'll be going to court for failing to comply with health regulations
You know, most of us would be expected to improvise on the job. It's part of the 'get er done' approach seen on all jobsites. I've been congratulated in the past for my on-the-fly fixes. But this time it went terribly wrong. Let's all learn from this man's tragedy.
Very unfortunate death. Would backing up the tanker have been easier or moving the tankers on the outside away from the inside 2? I mean they are mobile for crying out loud. Laziness cost a life this day.
Had the torque been clockwise he probably wouldn't have been hurt, very unlucky there. That said they're also very lucky that nothing else happened bc when the improvised nozzle came off the co2 would have been directed right at the adjacent queen. I wonder if another option would be to stager the tankers, enough to offset the side vents, allowing one to vent all queens at once in the same direction. I'm assuming the 300 ft clearance required is for objects in the direct path of the vent.
And they say computer science is still young with all the mistakes software makes....these videos go to show mistakes happen everywhere in every industry
I would never have the balls to mess around with that kind of PSI. You should not be making on site modification when you are dealing with 2 tons of thrust, unless you have all the necessary equipment and expertise.
I'm thinking that the employee didn't think. The second I saw that connection after being told the pressure and volume of the CO2 coming out of that valve I knew exactly what was going to happen before they even showed it. And I'm just a stupid carpet installer.
This is an example of "Vectored Thrust". There are a couple of ways this could have been done safer. 1) transfer the liquid Co2 into the next tank. 2) connect hard piping to a pressure vessel and out a flare stack. However, the solution of the vertical riser is very good and very useful (albeit after the fact). Excess Co2 is common on 90% of all jobs.
I work for Schlumberger in Canada abd all of our Queens are "blowndown" through plumming that is routed straight up and fastened to the side of the queen making this accident impossible on our equipment.
Why don't they use smaller pipes and valves to vent them ? You open it,and let it vent,no need to have CO² cannons to vent tanks,it's not like they were in a hurry.
me too. I learned today about how a cousin of mine died 20 years ago, squished by his Sears work truck while he repaired it. Trying to find a noise, he raised the back end, put it on jack stands, and put a jack slightly underneath the rear diff, in case it fell. THEN, the dumbass put it in drive, because the noise only happened when the wheels were moving, and went to go look under it. I think he deserved what he got, for being so stupid. What do you think?
vanamburgben, there was a man in the news last month (May 2018) who was performing car repair and jacked up his car.......................wait for it.........................are you ready?.................................. on soft ground. You can pretty much guess the outcome. Slid underneath, jiggled a part of the vehicle only to have the vehicle pin him down asphyxiating him. Luckily, his thrashing around caught the attention of several people who were able to lift the vehicle and perform CPR. Personally, i would have lifted the vehicle via jack, pulled him out only to throw the jack on his stupid head.
it is so important .... your job should be definitely taken to a higher level , not only investigating accidents, but more important as PREVENTION ... thank you and keep on with your good work !
He had the last elbow facing to the right so it just unscrewed itself mad fast. If he had turned the elbow 180 facing the rear it would tighten itself. Those are little things you got to think about when working with tankers and high pressures. 15 lbs of air pressure in a tanker and you stand on a top hatch and kick the locks off it will send you 30 feet in the air,add 10 ' to that cause you are up there.
It's companies like this that makes hard workers look bad, but the saying goes if you want something some right, do it yourself that's why I'm working on running under my own authority in the transportation industry. I may not have the most money but I'll have the best equipment.
open that valve slowly, I guess, and don't have it pointed so it will unscrew. He did not think this though. Still a discharge pipe in the back , pointed up is/was the solution, but sometimes it takes incidents like this for a problem to be discovered.
You'd think it would be acceptable to move a "queen" that is not completely empty, as long as it is below a specified weight. You'd think it would be normal to transfer to CO2 BACK to a tanker, rather than just vent it. They paid for it; why throw it away?
CO2 is liquid under pressure, just like LNG ("propane"). (That's why they can store so much in a container. Gases that don't liquefy at normal temperatures, like nitrogen, oxygen, and helium, are harder to deal with. You can liquefy them using extreme cold, or squeeze more into a strong thick-walled container using extreme pressure.) You would return the liquid to the tanker the same way it came from the tanker, by pumping it. CO2 is not as dangerous or expensive as propane, so it can pump itself. Connect the containers at the bottom (liquid), and then vent gas from the top of the intended destination container. The pressure in the source container will keep pushing the liquid across to the destination container.
LNG is natural gas (methane), not propane. LNG, like air, H2, N2, etc., are non liquifiable gas at room temperature. Regardless the pressure, they always stay gaseous. The only way to keep them as liquid it to keep them cold. CO2 can be liquified at below 31 degree C, above that, it stays gaseous with liquid like density, called super critical state. It's not easy to pump super critical gas to another tank, and this operation would require high cost equipment, anything to pump 10Mpa+ would be f*ing expensive.
Did this guy open the valve fast or what? I would of slowly cracked it and had gears that stepped down the turning speed ie. 10 full turns to open. A wheel probably would of been safer than a lever
The other solution is to have the driver vent the tank, eliminating all problems. The driver can be directed to hitch to the queen and check everything, pull out a short distance and once in a safe area, vent. A driver could also continue to vent while underway with this gas.
Liquid CO2? Carbon Dioxide forms dry ice when super cooled CO2 sublimates and transitions directly from a solid to a gas. These are high pressure tanks and not cryogenic tanks.
it would be liquid at ambient temperatures at ~80 atmospheres but 300 psi is just 20 atmospheres so it would be in the gas phase in the queens. possibly the CO2 is delivered as a liquid but is stored as a gas in the queens.
i work with steam and pressurized tanks. i have to open manholes to the tanks so that our lab can inspect the tanks and have to swing pipes that route our systems to different areas which hold pressure from the tanks they are connected to, depending on the current operation. i don't give a CRAP who says what and huh.. i vent those tanks MULTIPLE times through our exhaust pipe that blows through to the roof outside of our plant. vent once.. vent twice.. vent thrice... save ya life!!! (i made that up if ya wanna use it.) when your gauges act up and computer programs like to fault out.. it is better to be super sure.
after working the field i tend to read between the lines. sad truth is that super visor most likely knew full well the dangers and had those parked that way to save space for more trailers and put it on the workers to "just get it done!" and they came up with that pipe out of a lack of options otherwise because it was cheaper and faster to not move them. we had a mule that had a bad 5th wheel and i reported it several times, i refused to use it, i logged it in the driver log, the swing shift guy logged it and refused to use it, next day the new guy just did as he was told and lost a trailer. Exon came down hard on management ,,,,,,guess what .....they removed the logs! so now there is no accountability and its back on the drivers. now management can say....."i didnt know"

@@jutlan854 and what?
Queens are used for the temporary storage of CO2. They can only be moved when empty.
That event surprised me. The whole time, I thought he was going to die from asphyxiation.
zhzhuiui its hard to as you choke on it, unlike methane, etc
I heard tanker and thought explosion, then I heard high pressure CO2 and thought asphyxiation, but no, an impact.
I was thinking he opened the outlet valve for a septic pump truck.
That arms massive punching power must have crushed his bones even the mere sound of air pressure gushing out should have scared him away unless of course some ill conceived jack ass supervisor instructed him to fix it.
I thought the CO2 thrust was going to cut him apart. Rip poor guy
I like how it takes someone to die before anything is changed.
Yup, that seems to be the only way,...
Construction.
you can not learn without doing mistakes, altho for some ppl it ends with the last mistake they ever make
How are you supposed to change it beofre a problem occurs? Humans ignoring safety will always happen.

This was one of the scenarios that crossed my mind in just few seconds before the video revealed the horrible truth. One must always consider every possibility including the mechanical aspects of something especially with that much force be exerted.
high pressure can unthread things
Why didn't he just vent the outside queens and have them moved before moving on to the center ones?
Shane Brobst he didnt think or didnt have a driver or cab
Lazy?
They can only be moved after venting. They are used for temp co2 storage and should never have been positioned that way
Too simple
It's possible the outside ones were full and the middle ones were empty and not needed any longer.
Shortcuts always come with risks
In Alberta, we have the right to refuse to go do a specific job if we say, it is unsafe. More places should have that same right so people can go home to their families,

Nice, wait til somebody dies to fix your equipment, I hope the family sues the hell out of this company.
R.I.P. Mr.
Rest in peace ✝️
That's terrible. I hope his family is well.
I saw this coming. When I saw the pipe attachment, I'm thinking , that thing will spin of from the thrust. And that's what happened? Creeps me out that someone thought that would work.
@HelloHansSolo Probably a company name. Why can't venting be done using a remote solenoid? the oil companies have used that to regulate pipelines with successes for years
I worked for Sanjel frac and cement division. They are pretty safety orientated
was it necessary to go to full pressure asap while venting the queens? I would have turned the valve SLOWLY and made sure I was out of the way of any possible problem. Seems like a lot of pressure to be allowed to vent at 100% asap.
They probably did open slowly because whipping open the valve would be a major blast. I do agree though they shouldn't have been standing right beside it. The sound coming from it would have been loud as hell.
The torque produced by the momentum of the CO2 came as a surprise to me. Though it is easily noticed in a regular water hose.
2000 -3000 psi is no joke!!!
There should be a regulator on those valves too!!!!
Hvac nitrogen tanks use regulators too!
Slowly dial up pressure for leak test & drain clog clearance!?
Just a valve is not a well controlled set up!?
I'm not a trucker or fool with carbon dioxide & I know better than to let employees feel safe with no regulators on that!? Smh....
No wonder I can't find work!?
I have too much common sense?!
Bosses fire me when I question their motives?!
Had one lay me off after I told him they were using hydraulic hoses for refrigeratant lines Instead of braided hvac hoses!!!
It's ok tho.... next person if I work again will be blessed to have a worker with common sense(goes a long way!!!)
Orlando Johnson you can only say so much! Shame he didn’t listen to your advice.
@@leighcurran3423 wow, dude fire you for pointing that flaw out? In the long run, will see who'll be going to court for failing to comply with health regulations
You know, most of us would be expected to improvise on the job. It's part of the 'get er done' approach seen on all jobsites. I've been congratulated in the past for my on-the-fly fixes. But this time it went terribly wrong. Let's all learn from this man's tragedy.
never cut corners, take extra time for safety 🦺
Good, I'm glad they changed their safety regs on this, but as always it's little too late for the person who's dead.
Very unfortunate death. Would backing up the tanker have been easier or moving the tankers on the outside away from the inside 2? I mean they are mobile for crying out loud. Laziness cost a life this day.
The operator did not see it coming in more ways than one, and never knew what hit him, sadly.
Good educational vid for the rest of us.
Such method shoud be filed as LCO2 operation manual. There should be a mandatory training course for the truck driver by law.
This accident could have been PRE-VENTED.
The elbow became an impeller, probably because he fail to tighten enough. Possibly because there was dirt on the threads. It's really sad.
I have a pretty good sense of "This is a bad idea" but probably wouldn't have figured on the thrust unthreading a 4" pipe
Had the torque been clockwise he probably wouldn't have been hurt, very unlucky there. That said they're also very lucky that nothing else happened bc when the improvised nozzle came off the co2 would have been directed right at the adjacent queen. I wonder if another option would be to stager the tankers, enough to offset the side vents, allowing one to vent all queens at once in the same direction. I'm assuming the 300 ft clearance required is for objects in the direct path of the vent.
Engineering solutions should not be first.. elimination is first. Run the process to eliminate the need for blow down
Gawd, you are right!
As soon as I seen the way that was put together I knew exactly what happened anyone with a garden hose should have known better
And they say computer science is still young with all the mistakes software makes....these videos go to show mistakes happen everywhere in every industry
Maybe vent the outer two queens then move them then vent the inner two then move them and no problems?
Unfortunate guy. I coulda made the same mistake in that position.
I would never have the balls to mess around with that kind of PSI. You should not be making on site modification when you are dealing with 2 tons of thrust, unless you have all the necessary equipment and expertise.
How could the worker not see that coming?
The worker was doing what should have been formally done by engineers and integrated into the trailers.
I hope the family sued the company seen companies like this so many times they don't care all they think about is a dollar bill
I'm thinking that the employee didn't think. The second I saw that connection after being told the pressure and volume of the CO2 coming out of that valve I knew exactly what was going to happen before they even showed it.
And I'm just a stupid carpet installer.
This is an example of "Vectored Thrust". There are a couple of ways this could have been done safer. 1) transfer the liquid Co2 into the next tank. 2) connect hard piping to a pressure vessel and out a flare stack. However, the solution of the vertical riser is very good and very useful (albeit after the fact). Excess Co2 is common on 90% of all jobs.
I work for Schlumberger in Canada abd all of our Queens are "blowndown" through plumming that is routed straight up and fastened to the side of the queen making this accident impossible on our equipment.
yeah, all you have to do is stagger the queens so the next one in line is further back and the vents can just blow behind the next trailer
Not enough space on a lease
Or just point the valve up. Then it's the bird's problem.
@@fifthbusiness2591 That's literally what the worker did, thus causing the accident.
Looks a bit like Titan submersible.
Once I took the diffuser cone off a large CO2 fire extinguisher and I had an exciting torque experience too! Like a flying tank!
junkdeal 80
Thankfully you’re here to tell about it.. bet that made the adrenaline flow for a few
Why don't they use smaller pipes and valves to vent them ?
You open it,and let it vent,no need to have CO² cannons to vent tanks,it's not like they were in a hurry.
Educational but sad. One small mistep, one mistake, and it's over. God rest his soul. Work safe men. Please.
Me: time to sleep.
TH-cam: Safety video?
Me: yes
the man made a difference
I figured fittings would be involved somehow but that outcome was still surprising.
Should've moved the outside queen's when they were empty , then empty the middle ones
Rest In Peace ✌️
These kind of accidents piss me off
me too. I learned today about how a cousin of mine died 20 years ago, squished by his Sears work truck while he repaired it. Trying to find a noise, he raised the back end, put it on jack stands, and put a jack slightly underneath the rear diff, in case it fell. THEN, the dumbass put it in drive, because the noise only happened when the wheels were moving, and went to go look under it. I think he deserved what he got, for being so stupid. What do you think?
vanamburgben, there was a man in the news last month (May 2018) who was performing car repair and jacked up his car.......................wait for it.........................are you ready?.................................. on soft ground. You can pretty much guess the outcome. Slid underneath, jiggled a part of the vehicle only to have the vehicle pin him down asphyxiating him. Luckily, his thrashing around caught the attention of several people who were able to lift the vehicle and perform CPR. Personally, i would have lifted the vehicle via jack, pulled him out only to throw the jack on his stupid head.
Woah. So sorry for the workers family.
it is so important .... your job should be definitely taken to a higher level , not only investigating accidents, but more important as PREVENTION ... thank you and keep on with your good work !
@AugustusLarch you mean that its a lever ball valve? those open in one quarter turn, full open to full closed
He had the last elbow facing to the right so it just unscrewed itself mad fast. If he had turned the elbow 180 facing the rear it would tighten itself. Those are little things you got to think about when working with tankers and high pressures. 15 lbs of air pressure in a tanker and you stand on a top hatch and kick the locks off it will send you 30 feet in the air,add 10 ' to that cause you are up there.
You should be able to vent it from a distance. A remote control system would be good
Seems like a good idea at the time
But wouldn’t venting up leave residual in the tank and pipe CO2 being heavy and all
not enough to matter
What a tragic & totally avoidable loss of life! The victim's family should file a lawsuit demanding millions.
The worker made the wrong decision on his own!!! (nobody forced him to improvise). His own fault!
It's companies like this that makes hard workers look bad, but the saying goes if you want something some right, do it yourself that's why I'm working on running under my own authority in the transportation industry. I may not have the most money but I'll have the best equipment.
Wow how sad. Some times a little mistake could cause a deadly disaster.
I've been binge watching these for the last few hours and I'm afraid to leave the house at this stage. I see danger everywhere now.
A little paranoia is a healthy thing
open that valve slowly, I guess, and don't have it pointed so it will unscrew. He did not think this though. Still a discharge pipe in the back , pointed up is/was the solution, but sometimes it takes incidents like this for a problem to be discovered.
You'd think it would be acceptable to move a "queen" that is not completely empty, as long as it is below a specified weight.
You'd think it would be normal to transfer to CO2 BACK to a tanker, rather than just vent it. They paid for it; why throw it away?
CO2 is liquid under pressure, just like LNG ("propane"). (That's why they can store so much in a container. Gases that don't liquefy at normal temperatures, like nitrogen, oxygen, and helium, are harder to deal with. You can liquefy them using extreme cold, or squeeze more into a strong thick-walled container using extreme pressure.) You would return the liquid to the tanker the same way it came from the tanker, by pumping it. CO2 is not as dangerous or expensive as propane, so it can pump itself. Connect the containers at the bottom (liquid), and then vent gas from the top of the intended destination container. The pressure in the source container will keep pushing the liquid across to the destination container.
LNG is natural gas (methane), not propane. LNG, like air, H2, N2, etc., are non liquifiable gas at room temperature. Regardless the pressure, they always stay gaseous. The only way to keep them as liquid it to keep them cold. CO2 can be liquified at below 31 degree C, above that, it stays gaseous with liquid like density, called super critical state. It's not easy to pump super critical gas to another tank, and this operation would require high cost equipment, anything to pump 10Mpa+ would be f*ing expensive.
Always takes a death for shit to be redone
Did this guy open the valve fast or what? I would of slowly cracked it and had gears that stepped down the turning speed ie. 10 full turns to open. A wheel probably would of been safer than a lever
At least the opening valve should be mecanical remote cotrolled from the opposite side of the tanker.
And this is why I stick to dry bulk pneumatic. It’s got it’s own dangers, but compressed gases are an entirely different animal.
The other solution is to have the driver vent the tank, eliminating all problems.
The driver can be directed to hitch to the queen and check everything, pull out a short distance and once in a safe area, vent.
A driver could also continue to vent while underway with this gas.
Liquid CO2? Carbon Dioxide forms dry ice when super cooled CO2 sublimates and transitions directly from a solid to a gas. These are high pressure tanks and not cryogenic tanks.
it would be liquid at ambient temperatures at ~80 atmospheres but 300 psi is just 20 atmospheres so it would be in the gas phase in the queens. possibly the CO2 is delivered as a liquid but is stored as a gas in the queens.
And how many tons of c02 is dumped like this each year from how many wells how many countries?
Tons of pollution, they don't care
@@Nicholas-f5 c02 is pollution? It's what keeps plants alive.
@@williambrown7203 you can’t drown in water? It keeps plants alive
Mike Bertrand is not mad, he's just disappointed.
i work with steam and pressurized tanks. i have to open manholes to the tanks so that our lab can inspect the tanks and have to swing pipes that route our systems to different areas which hold pressure from the tanks they are connected to, depending on the current operation. i don't give a CRAP who says what and huh.. i vent those tanks MULTIPLE times through our exhaust pipe that blows through to the roof outside of our plant. vent once.. vent twice.. vent thrice... save ya life!!! (i made that up if ya wanna use it.) when your gauges act up and computer programs like to fault out.. it is better to be super sure.
after working the field i tend to read between the lines. sad truth is that super visor most likely knew full well the dangers and had those parked that way to save space for more trailers and put it on the workers to "just get it done!" and they came up with that pipe out of a lack of options otherwise because it was cheaper and faster to not move them. we had a mule that had a bad 5th wheel and i reported it several times, i refused to use it, i logged it in the driver log, the swing shift guy logged it and refused to use it, next day the new guy just did as he was told and lost a trailer. Exon came down hard on management ,,,,,,guess what .....they removed the logs! so now there is no accountability and its back on the drivers. now management can say....."i didnt know"
