Looks like anybody’s ring muscle, also referred to as ass, after a bowl of Mexican chili bought from a questionable street vendor.

Ahh... reminds me of the good old days working on the Nord Stream....

... Mach diamonds?!

Each tonne of methane is equivalent to 36 tonnes of CO2. Just consider that. In most of Europe and the developed countries, this kind of venting is illegal unless there is an emergency.

And here we have an example of why some regulation/enforcement of things like safety standards is necessary.

Just joking ! ( that blow off would heat my house for a LONG time ) .... ( ? ) ......... DAVE™🛑

Any idea what the PSI is?

Pilot operated relief valve? What was the line pressure? Anyone have a match?

I don´t have any Idea whats going on but the mountain view is niceeee.

That was probably enough gas to power a fair sized town for a month

8 years later youtube suggests this to me.

for reference purposes, 170 db is what the space shuttle launch is. so this guy basically knows what it would be like to stand beside the launch tower of the space shuttle launches.

The gas was coming out so fast at first there were visible shock diamonds

Call Greta , NOW ( ? ) ... Methane emissions ... ( OMG , global warming ? ) ............... DAVE™🛑

Is there any way to attach an extension to the pipe before you do the blowdown? A standoff with a diffuser at the end would move the frequency spectrum higher, and the source farther from the person. Any vent with a pressure ratio above 2:1 will have sonic flow at the exit (as shown by the huge mach diamonds in the flow). Those mach diamonds are 194 dB (the max from a shock wave) at their source, with a base radius of the plume diameter. If you can add a showerhead with a hundred smaller openings for the same area, the R_0 is ten times smaller and the sound power level will be much lower at any distance because the individual noise sources partially interfere with each other. Just moving it up six feet gets it farther from your head, and the high directionality will also help. (In testing rocket engines, I really could feel how the loudest area was about 45 degrees off the blast direction, so getting the vent up higher will help a lot.) There are drugs which if taken before or shortly after a noise exposure, can reduce the immune system cascade that make the damage permanent. Avenanthramide is one of them, if you search on it you should be able to find more references. www.nature.com/articles/s41420-019-0195-1

Is that natural gas being vented? Or just compressed air used to test the pipeline?

One should think that these days this operation should be doable by a remotely operated robot, which does not care the least of 170dB. I mean, we are flying to the moon and mars, landing on them, with highly complicated calculations and manoeuvers, but the act of going to a certain position and turn a wheel still requires human interaction? If there is one useful use of robots, then this is it.

Seems like a waste of gas

Anyone got a light?

and on that day, we learned why there were no smoking signs all around that area.

Where is this compressor station? And what kind of engines does it use?

Good video. What is this DLP? Thanks.

Hey, there's a wikipedia page about pipeline blowdowns producing shock diamonds that's in need of a citation. This seems to at least provide visual evidence that it happens at both 0:18 and 0:55 Mind if I grab a screenshot from either timestamp for use on the Shock Diamond wikipedia page, with attribution? If so, what license from the Wikipedia File Copyright Tags page can I use? (hoping for Creative Commons Attribution Share-Alike 4.0, but up to you)

Anyone got a light?

They should at least have some sort of riser on that valve to help protect you guys!

I think they blew through five years worth of emissions.

Damn, there's 3 mach diamonds at the start. I can't imagine the sound the operator experiences. From a noise-level perspective that's gotta be like sticking your head three or four feet from a fighter jet running the afterburner.

I would love to see what would happen if someone shot a flare gun at that.

Gas control quick as fuck rerouting the low pressure

Why they shut down?

Its the portable CNC mill cutter!

That was 129 db at 50 ft loud i bet.

That's really cool

Preparing for liftoff in T-,minus: 3..2..1

Jesus! Save us!

Been on the compressor stations. We do a lot of field commissioning with our company. I've seen, and heard an ESD. It's the loudest thing I've ever heard in my life. This video only represents a small fraction of how loud it actually is.

Heavy pollution man

Geez!

Damn those shock diamonds are insane

Poison

As awesome as it is on video, nothing can capture the sound or just how menacing that plume really looks and feels. Opening one intentionally is nervewracking enough; walking up to one to close it after an unplanned release feels like sure death every time.

Bettis actuator in the mlv, next monday we will perform the purge and load process on chihuahuas nat gas pipeline 560 km

That's looks like very high pressure, what causes that pattern where the gas comes out?

the speed of that blow is beyond sound barrier... cool

I used to dive by one of these. When my mom was a kid they actually had to close the highway for a while because they had to dump a bunch of gas. I never witnessed that but did drive through the intense smell of gas a few times. Was thankful I didn't blow up. I know natural gas is lighter than air, what about the odorant?

You know, another way to stop greenhouse gas emissions is if everyone stopped farting so much!

This just happened where i live this week. The residents nearby had no idea what was going on. Their houses filled up with gas odor and they think they have hearing damage. Some want to move now. Must suck having that near your house. It is tenessee gases pipeline.

Thx for greenhouse effect mate 😡

Do you happen to know how much gas was emitted in this 1 min video? Also, is there some way to collect and use the gas instead of wasting it in the atmosphere?

psi?
