What to do with Liquid Oxygen?

[ZeZesRevenge]

Hİ everyone!

 

I see videos around about liquid oxygen.I don't know what to do with it.So my question is: What to do with liquid oxygen and should I make liquid oxygen?

 

Thx for all your answers guys!

Several builds back, the best way to convert polluted oxygen to clean oxygen was to turn it into liquid oxygen.  At the time, filtration medium (sand) was extremely limited and by cycle 500 or so, you would run out.  Since then, sand (or regolith) has become an unlimited resource, so filtration is no longer an issue.  Pufts (with the addition of ranching) can consume an incredible amount of PO2 for slime, and the environmental suits let you wander around in toxic biomes without concern.  This all means that it is no longer necessary to build a  LOX machine.

That said... you can still build a LOX machine if you desire.  Maybe you need to store up a LOT of oxygen for some reason.  Liquid oxygen is far more dense than gaseous.  However, its cold -- very cold.  You'll have to warm it up before your dupes try to breathe it.  OR you can use it for a coolant for things you want kept ultra-cold.  Or if you want to flash-freeze CO2, or make your Chlorine vent spew liquid instead gaseous chlorine...

@ZeZesRevenge To turn (slimelung infested) polluted oxygen (PO2) into O2. It requires no duplicant interaction and is guaranteed to destroy slimelung during the process but it requires a lot of power and quite some time/ressources to build and prime. A deodorizer based solution requires no power but duplicant interaction and is built cheaply and quickly, however it takes time or a slightly more complicated setup for the slimelung to get destroyed in the resulting oxygen.

You might need to build a PO2 based oxygen production at some point. For example if you want to sustain a very large colony and/or greenhouses for plant based food.

@KittenIsAGeek Normally a liquid oxygen production is more or less neutral in temperature I/O. A couple of wheezeworts will help to prime the system and slightly cool it down but in the end people often use the resulting liquid oxgen to cool the regulators or aquatuners which are used to cool it in the frist place, so the output will not be all that cool.

@clickrush the deodorizer method doesn't need dupe interaction as sweepers can load the sand

Also you don't have to wait for the slimelung to die off just use it to supply exosuit docks.  

I don't know if bug but dupes don't contract slimelung using exosuits that have been charged with slimelung rich oxygen

I just realized the new gas storage might disinfect slimelung if the tanks are submerged in chlorine, I'll test this in a few hours

So I shouldn't convert my O2 into LO2 but my PO2?

Converting O2 to LO2 has applications, but they are limited.  If you have a truly massive colony, it can help because you can pump 20 kg of oxygen to your base every second, which is enough for 200 dupes (ignoring diver's lung or mouth breathers).  You would have to heat it up when it gets there though.  To do that with gaseous O2, you would have to have 20 gas pipes and 40 gas pumps, which is more of a power cost than the LOX machine.  You probably would still want to liquefy PO2 in that case.

So, essentially, no, there is no real need to do that.  200 duplicants is considered excessive by most people.  Even if you had that many dupes, you probably wouldn't have a central oxygen generation system and, instead, have many small oxygen generation plants spread out across the colony..

You could use a liquid valve and regulate it for 10, 20, 100 dupes, you only need to do the maths, and you use less power.

Again the whole point of producing liquid oxygen is the conversion from PO2. This was first introduced by players to build sustainable bases before there were any geysers, so you couldn't sustain one with electrolyzers. Now if you have enough sustainable geyser/vent water to burn there is really no actual *need* for this.

ever want a machine to counter heat creep?????  thermal regulator on a loop with a max temperature output fed to a thermal regulator or occlusion point?

Thx you guys now I know about LO2!
