Trying to Learn Gas Liquifaction

[acolyteofrocket]

So.

 

I understand that you can use polluted water to cool things using a water sieve to remove the heat, and that a similar trick can be done with a steam turbine.

But if I have a stream of gaseous hydrogen (say) I can't put it through a thermo  aquatuner (wrong phase) or a thermo regulator (breaks gas pipe when liquid forms).

This is the part I am stuck on, plz help...

If your intent is to make liquid oxygen or liquid methane for example using hydrogen inside a thermo regulator cooling loop you have to use a pipe sensors with an automation valve before the TR to bypass the TR if the hydrogen is like 15degrees warmer than it's condensation point. Let the packets that are too cold bypass the TR and cool some more so it warms up to a save temp to get cooled again.

Another trick is to automate the TR itself with a thermo sensor that sits inside the condensation chamber. When it reaches -163°C (condensation point of oxygen I think or was it -183, dunno) the TR shuts down. Now you just need a pipe bridge that circulates the hydrogen around the TR so the hydrogen keeps circulating without TR cooling.

I will try to find somewhere a screenshot, I'm on my mobile phone atm. Maybe someone else will pitch in a screenshot

It is a mere matter of cooling something else down which of course can only be liquid or gas. That's where the new coolant liquid comes into play since hydrogen had the lowest condensation point which no liquid could reach.

"Simply" cool the Hydrogen shy of being condensed into liquid (gas pipe thermo sensor to prevent breaking) and then let the coolant run through the insulated chamber (liquid thermo sensor to let it stay as long as it should and no longer).

Gas Pumps by the by have the advantage of producing no heat or on the contrary, liquid pumps do have the disadvantage of doing so. Moving 10kg of Hydrogen heats up 4166g by 1°C but coolant should be able to easily counter that.

Ok....I found an example pic on Google for the bridge bypass when the TR is shut off

Ok, baby steps - Thx for the responses.

So I can cool a gas by using another  gas coolant that has an even lower boiling point than the gas I am trying to cool, in a Thermo Regulator - thats logical, I can do that (I think  )

But what about hydrogen ? I got the impression from the internet/youtube scene that it was possible to liquify hydrogen without needing to launch a rocket - how is this done when there is no gas available with a lower boiling point ?

You get the hydrogen near its condensation point, then use a valve to let only small amounts into the TR ( I forget how small it needs to be for gas... iirc, liquids are 1000g/s ), and the small packets of gas won't condense inside the pipe.

There is this ''bug'' at the moment...at least I consider it so, but I don't care really, don't have to exploit it...If you run small amounts of gas for example through the TR you can cool it lower than condensation point I think it's 100g...keep in mind not to overfill the condensation chamber with too much h2 that you like to condense...because the 100g inside the pipe won't cool like a huge room with 2kg per square very fast, logical, right....so to recap....100g h2 inside a cooling loop cool small amounts of h2(best to precool it close to condensation and let like 50-100g/s via valve in) inside the condensation chamber to condense

Well i think the intend of the devs was to use the super coolant. Iirc it feezes at 1K so if you manage to cool it low enough you can use it to liquify hydrogen.

Other than that i think there are a few expliots to liquify it.

[acolyteofrocket]

So then it looks like the devs intend for us to get this super coolant and they might also fix the bug/exploit. In which case now might not be the right time to learn the latter stuff.

I am in about cycle 670 and have only recently broken into the space biome for the first time ever. I was trying to get ahead of the curve and figure out if I had any long processes I needed to start to get gas liquefaction going, since I am aware it is needed for later rockets. But now I am desperately trying to save what is left of my asteroid from the meteors ..... 

I might look into the 100g trick Yoma_Nosme mentioned or at least do some calcs,  but it might be a few days away yet.

Thx for all the help guys
