This has been bothering me for a while, and It's hard for me to find a source online...

But how the fuck do some companies fill those pressurized tanks? It's boggling my mind. All this nitrogen at like 2000psi. wtf?

What about it do you find boggling? Seems pretty straightforward. Pressurize gas. Connect tank. Open valve. Close valve.

>>5468772
How is the gas fed into it? Is it a chemical reaction fed into the tank? Pretty much forcing gas in one direction?

What the fuck? The gas goes from a high pressure tank into a lower pressure tank (the one in your pic)

The source gas is at higher pressure. Open the valve and the gas rushes into the empty tank until the pressure equalizes.

That seems like a normal answer to you?

It's an endless cycle of using pressurised tanks to fill other pressurised tanks. No one knows how and where it originally started and how the first pressurised tank got filled

>> No.5468856

>>5468851

The question was how do they get it in a tank.
The answer is to connect it a volume of pressurized gas.
The next question was how to pressurize that gas.
The next answer is literally just to take a volume of gas and apply pressure. Literally. Pushing on it.

I have.

I have never squeezed a ballon into a smaller ballon, nor have I taken apart a bicycle pump to see how it works, nor have I toured an industrial setting that compresses gas and seen the machines that do it.

Do you know how gas is compressed in industrial settings? That is what I really want to know. (Not OP, btw)

>I have never squeezed a ballon into a smaller ballon

But you could, though. Decrease the volume and you increase the pressure.

>nor have I taken apart a bicycle pump to see how it works

It's just a piston in between two one way valves. Suck air in by expanding the volume, then force it out by compressing the volume (and thus increasing the pressure). In other words: take a gas and apply pressure.

>Do you know how gas is compressed in industrial settings?

No, but it's not hard to guess. Just big, fast versions of that bicycle pump, powered by motors instead of your arm.

making this up but i would imagine
>large cylindrical chamber, put gas in it
>bottom of chamber is the head of a piston
>force piston up, keep gas sealed in chamber, gas is compressed to shrinking volume of chamber
at least for the basic part, then you move the gas into another chamber, maybe you immediately force it into the other chamber through a pressure valve during the piston action so you can compress more in one pump

>> No.5468890

They probably use some kind of pump.

>> No.5468897

>>5468883
No need to be such a dick about it, if he's never seen how a pump works and doesn't know much about physics it isn't immediately obvious that "Take gas, apply pressure" refers to that mechanism and he was presumably looking for a more specific or visual answer than such a meaningless conceptual one.

>> No.5468905

They start with a very large, thin-walled tank, like a steel balloon, fill it with normal-pressure gas, and squish it down in a car crusher full of rubber balls until it's a normal-size, thick-walled tank filled with high-pressure gas.

What kind of pressure and what kind of volume do you want? Low volume and low pressure? Bike pump. Low volume high pressure? Stirrup pump. Low pressure high volume? Air compressor. High Pressure high volume? Scuba compressor. Ultimately it depends on the gas and the application, but usually a gas is initially pressurized by a compressor.

wtf?

You take a big tank of gas connected to a smaller tank and heat up the big tank. The gas gets hot and therefore pressurizes inside the little tank. Close valves between tanks and now you have a tank of pressurized gas.

You're a pure idiot!
Gas is transported and compressed by a compresser (a pump for gases) in a big tank. Then this tank is connected to small empty tanks, the pressure equalises (will be high in small tank and a little lower in big tank than it was), then it's disconnected.
They liquify air for nitrogen, oxygen and argon. Don't ask how they reach -200 degrees temperature, you will not inderstand.

>>5469712 >Don't ask how they reach -200 degrees temperature, you will not inderstand

They vent it to very low pressure rapidly resulting in a serious drop in temperature. However you can see the pressure/volume/temperature relationship and it is impossible to have liquid gas at low temperature and high pressure.

We must all believe in the Great Compressor! Just as mundane compressors push gas into areas of higher density, so too will the Great Compressor push our souls into a high plane!

How else could we have pressurized gas? There is an infinite cycle of compression, and it all began with the Great Compressor itself!

Who talked about selling nitrogen?. I'll build the worlds largest cryogenic storage tank and condense out CO2 from the atmosphere. Getting millions of green grants and investments.

Then I'll go rogue and demand even more money to not realease it all in a cataclysmic global warming disaster event(formulated as "ohnoes, or cryogenic machine thingy needs more funding or it may set the CO2 storage on fire!")

I'll then reinvest the money into an even larger storage and suck the oxygen out of the atmosphere instead(blaming those pesky plants for not producing oxygen if we don't support global warming by giving them CO2) , and repeat the cycle until I've monopolized the entire atmosphere.

Or maybe I should just look into politics
