In this video I'm going to Liquify Methane / Natural gas with my Mixed-Gas
Joule-Thomson Cryocooler. Methane liquifies at -162C under ambient
pressure, but at elevated pressures, it can be condensed as high as -85C.
In this experiment I'll condense some at -118C / 12 bar of pressure.
My cryocooler was meant for making liquid air or liquid nitrogen, but I
figured I'd try liquefying some methane along the way to see if there's
any pitfalls / issues with making liquefied natural gas (LNG), which there
definitely were.
The joule-thomson cycle works by compressing gas and then expanding it,
which forces it to drop its temperature. By back-flowing the cold low
pressure gas back over the high pressure gas in a counterflow heat
exchanger, the cryocooler creates a positive feedback loop that drives the
temperature down into the cryogenic range. The lowest temperature I
recorded was -180C.
Using pure methane or pure nitrogen would require hundreds of atmospheres
of pressure in the cycle to reach the desired temperature, but by using a
mixture of gases with different boiling points (similar to an
"autocascade" refrigeration system), the same effect can be achieved at
just 20-30 bar which a repurposed air conditioner compressor can handle
without any problem. For liquefying Methane, a gas mix of Propane,
Ethylene, Methane, Argon and Nitrogen is used. The same components are
used for liquefying Nitrogen, but in different proportions to optimize
heat lift at lower temperatures.

Liquid Methane / LNG is becoming used more frequently both for power
generation and vehicles because it has an energy density similar to
gasoline/diesel/kerosene, but is extremely easy to ignite/burn and burns
very clean. In the near future, hardware will be delivered to the moon via
LNG-burning rockets (starship). At the hobby level, I don't see much use
for it, but it's a fun science experiment since this is technically the
first cryogenic liquid I've produced.

    I don't know if you own or are renting your house but if you are renting it may not be code so you will want to revert the system back before inspection as I am sure such a use may fail inspection. Even if you own the house it may fail the inspection of the system to ensure it is still functional. Removing moisture is also good because moisture can destroy the compressor and even the oil. I think it causes the oil to become acidic and breaks down the varnish on the windings and causes a short.

    Do you have any hints for using old fridges as there might be very bad refrigerant in it? Would you take some precautions or would you just open it outside and let it go as the same would most likely also happen on a recycling plant? I mean also if you got a refrigerator which compressor is working but it's not cooling it has probably lost most of it's refrigerant anyway 😅

  • @KanjiasDev
    @KanjiasDev Před 2 dny

    Wouldn't it be better to have opposite flow rate in the Coaxial heat exchanger? I mean that would give you a much more stable temperature difference as the warmed up gas would cool the 'hot' gas on the condenser inlet side and towards the outlet side of the condenser both would get cooler (the refrigerant in the condenser from cooling and the one in the evaporator from being fresher) - don't feel bad if you gotta correct me, I'm happy to learn if there's a mistake in my thought process ✌️

    The cheater's method for a Joule-Thompson cycle is to throw consumable cash at the problem, you can get down to liquid nitrogen temps with a standard 150psi shop air compressor IF you precool the high-pressure air in a dry ice/alcohol bath. Yeah, you're gonna chew through dry ice like there's no tomorrow, but that stuff is dirt cheap compared to liquid nitrogen or liquid oxygen, which is the mix you're gonna achieve with it. It's even higher yield if you have a higher pressure compressor, if you use a standard tankless compressor head hooked up to a CO2 fire extinguisher tank you can get 500-800 psi if you lower the pulley ratios or put a larger motor on the compressor head. Filter/dryer can also be integrated in that case, fill the extinguisher tank through the gauge port but drain it through the hose port and you can pack the bottom half of the extinguisher with dessicant beads.
