Making Liquid Nitrogen From Scratch!

I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: starbucks.app.link/derekmuller
Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.
Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.
A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.
Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.
It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

Well, the method I thought about is much simpler but probably less efficient

[@srpenguinbr]

You cool down air and keep track of the temperature. When it is still a few degrees above -193°C, you maintain the temperature and remove all the liquid that forms. That will be the other gases you don't want. Get below the fusion point of N2 and there you get the precious liquid. Anyways, it is nice to see some of the tech he used. I had never imagined a refrigerator like that existed

[@theophrastusbombastus8019]

@@srpenguinbr The problem is that O2 has a very close boiling point so you would still liquefy it. A method more "from scratch" would maybe be like burning all the oxygen before cooling it.

[@StaceyGreenstein]

So, when liquifying a gas, it is handy to place the container on a scale during the process. As the gas liquifies, it becomes more dense. More dense, but same volume = more mass. More mass in a non-inertial frame of reference (ie, a "gravity field") has more "weight". You can then check the scale during the process without disturbing the process, to see if, and how much, liquified gas you have created.

[@virt1one]

I too was wondering why they were not using a scale. Although that could be an expensive prospect. Precision scales usually don't have a very large range, and the weight of the flask/dewar/whatever might exceed the weight limit of a scale with enough precision to notice the liquefaction. The other problem of course is the seal they had to use for the nitrogen. When doing oxygen they didn't need such a seal, and the flask could just be overlapping loosely with the nozzle. But the nitrogen required a seal, and that definitely would dampen the reading on the scale. Thinking a bit on this... they might have been able to use a simple arduino "pinger" that measures distance via ultrasonic ping, with that shooting into the flask and measuring the depth of liquid. That would only require wires leading out, and could be integrated into the seal. This might be improved by adding a "float" - a sheet of something that would float on top of liquid nitrogen, to provide a better target for the pinger or maybe a laser distance measurement tool?

[@heikoh.1618]

The container is attached to the cooler. You need an exact scale that can handle a fairly high weight

[@BeardedScienceGuy]

You could have also added a balloon to the system and set the flow rate where the balloon was neither expanding nor contracting, thus matching the flow rate to the condensation rate.

I just learned why medical fields use so much helium. I never understood how helium was used in refrigeration until now and I'm absolutely blown away. Also I'm happily supprised how well this project went.

[@riverstun]

Yup. NMR. Superconducter coils. You need very stable magnets, (sub-parts per million), so you need very stable electrical current, and the best way of getting that is to short a current into a superconducting coil. You disconnect the power, and the current just keeps going round and round. Superconducter coils need low temps, hence liquid helium. Which is sitting in a jacket of liquid nitrogen. which boils off before the helium does, keeping the helium cool and not needing refilling so much.

[@mrchangcooler]

If you want to be more specific, the reason helium is used particularly in this application is not only because it doesn't liquify, but also because helium, being a light gas, is easier to push around making it more efficient in the cryocooler- which is actually just a stirling engine in reverse.

[@drampadreg1386]

And we are running out, once it's gone it's gone.

[@nikkiofthevalley]

@@drampadreg1386 We're nowhere near running out of helium. And it's the same with any other natural resource. Technically, we're also "running out" of iron, but are we anywhere close to excavating every single iron vein in existence, and have we tapped into every single way of getting iron? No.

combine the compressor with a liquid evaporation phase change cooler, just water in a vacuum tube, 2kJ/g heat transport by gaseous form up, liquid form down after cooling at the top radiator

[@art.alagna.design]

How cool! How long does the liquid nitrogen stays liquid for, before turning back into gas state?

[@monkieassasin]

That all depends on the pressure you’re keeping it at. Phase changes depend on both temperature and pressure. If at atmospheric pressure, then it becomes a gas again at 77K. As for how fast a quantity of liquid nitrogen will completely boil away, that all depends on the container and how exposed it is to that temperature. For example putting liquid nitrogen into water will boil the nitrogen a lot faster than it simply sitting exposed to air.
