Steam & Liquid Oxygen how and why?


Recommended Posts

Heya everyone so i have seen a few posts now in which people talk about boiling water to get steam, or get the Temperature really low to turn contaminated oxygen into liquid oxygen. I'm fairly new on ONI and the best I could get was 56 cycles until I ran out of edible food and the butterfly effect took in and everything went to ruin. I've never really cared about the temperature but got curious. so why is it good to turn water into steam isn't it a waste of water? also, why does steam replace sand. the other question is how does that liquid oxygen thing work how could I get a room cold enough to turn oxygen into liquid oxygen. if no one minds to explain this to me and how to create such a set up I would really appreciate that.

Boiling water to get steam is done with contaminated water so that after it becomes again liquid it will be normal clean water.
It "replaces" sand because it can be used instead of filtering contaminated water which needs sand.

Check for example this video: https://www.youtube.com/watch?v=cn0nAH3Oz7s

And for cooling contaminated oxygen I use setup with only one thermo regulator, long gas pipe and gas vent which needs to be opened for "contaminated oxygen" at right moment. (when oxygen is bellow -183.15 in liquid form).
It needs about 3 days (cycles) to make liquid but there is no contaminated oxygen lost and low power is needed. I open it at -190 so everything in pipe is liquid and then when I have too much inside I can freeze my complete farm with 80 flowers so that all seeds pop out because air around them is bellow zero :)

I use my battery chambers to cook some water as the batteries where 124°C you can't just flood the room. Max amount of water output per 12 batteries is about 17g/s.  (right side of the base)

 

The cooling chamber is 5x2 in my base connected with 4 a/c's and also a long pipe to gather about 4tonns of contaminated oxygen before start injecting it to liquify. Needs about 1 or 2 cycles to convert all. (bottom left of the base)

The oxygen liquifing will need a lot of energy. This is why i built about 80 big batteries in my base so i can run processes with a high power usage without getting blackouts. Also i use a hatch mob to produce coal which i need for the coal generators. Those i turn on while i use the liquify chamber to avoid loosing to much power.

This is another example how to make liquid oxygen from my test colony with only one thermal regulator:

Little less then 72 kg (36 x 2) of contaminated oxygen changed to 58.8 kg (3 x 19.6) of liquid oxygen.

I've some questions : your Thermo Regulator have no Outake pipe?

The vacuum room is obligatory?

The vacuum is to show u that there is liquid oxygen cause vacuum is -270°C. And out take pipe is behind the thermo i think

No vacuum needed, I made this only on my test game to see how effective it is in changing contaminated oxygen to liquid and then normal oxygen.
Output from regulator goes back to input because it needs to cool that same oxygen many times (maybe around 20)... so you need to open filter manually when temperature is right.

I wanted to calculate how much oxygen I can get from toilet morb farm like this:

Normally you would let partially cooled gas out and then suck back into loop so that when it is in liquid form it drops out "automatically" but that has even lower effectiveness because of some gas being lost always when going into pump.

But I never finished that calculation because dupes are using waaaay too much oxygen for this and it is probably good only for cooling.

I mean 55kg in 3 days? ... that is only for one dupe and for one day. So for 10 dupes in 3 days I would need 30x more contaminated oxygen and that would need more regulators and less effective system with gas going out and in so I cant even imagine how many morbs that would need. Maybe 100 and in room with chlorine.

and what are u filtering in the first gas filter? I mean why do you do that? 

Only to let in just contaminated oxygen and not some other gas, not really needed for this test.

how u power up 10 thermos?

Lots of batteries to back up, 3 coal generators and 5 manual generators working 24/7

I actually use 17 to liquefy contaminated oxygen estimating a max possible temperature of 55ºC
