Making and storing Liquid Oxygen

[Neotuck]

This is my current design making LOX.  On average this produces and stores 200g/s of LOX

Starting from a PO2 vent plus twenty morbs the PO2 gets pre cooled by the temp shift plates, the temp sensor is set to -50C

Hydrogen is pumped though a series of regulators.  The temp determines how many radiators are used

Also the cooled PO2 can only pass though the doors to the condensing room of the LOX tank if the tank on the far right has no LOX to trigger the hydro sensor AND there is no PO2 at the bottom of the condenser tank to trigger an atmosphere sensor 

A conveyor loops diamonds though the hydrogen room to the condenser room were the PO2 cools down and turns into LOX.  Where it is them pumped into the next room to be stored.  The diamonds in the LOX tank make sure the LOX stays cold

EDIT UPDATED PICTURES

I made some improvements check out latest post on my tread to see all the changes made to my LOX maker

Holy moly...

Normally morbs die when the temperature falls below 10°C. They should definately not survive -50°C but i have a slickster at -1°C in my game and he doesn't seem to mind. What's going on? Is the temperature limit for critters actually implemented in the game or not?

Nice liquid oxygen maker though

A new feature, or a new bug. God knows.

body temp at -51.1C and still have full health 

[Hakon]

I see, I hope they change that. However this bug/new feature makes a lot af things possible like feeding slicksters 500°C, same with pufts. and also liquid oxygen setups with morbs in the cooling chamber like this!

Morbs aren't necessary.  I added them so there wouldn't be any downtime during the 10 cycle dormancy of the PO2 vent

Quick question @NeotuckThe closely clustered thermo switches on the tempshift plates - why place them there?

Isn't the temperature being aggressively spread between the temp shift plates anyway, and if so wont there be virtually zero difference between switches ?

guess I forgot to explain those 

yes the temp shift plates make sure the temperature is the same for all 4 sensors

Starting from the top the sensors are set to:

above -210C

above -200C

above -190C

above -180C

 

So if the hydrogen is more than -180C then all 4 sensors are on allowing all 4 regulators to be used

If the temperature is -195C (like in the picture above) then only the 2 top sensors will activate and the hydrogen will only be pumped through 2 regulators

If the temp reaches -210C or below then all 4 sensors will be off, the pump will then turn off, and any hydrogen left in the pipes will bypass all regulators

FYI (I modified the regulator room and turned it into a borg cube to keep the water cold)

I'm not sure if diamond is the best matrial for the conveyor radiator. Diamond has great heat conductivity but relatively low heat capacity. With this size, even pipe radiator containing cooled hydrogen could be enough to freeze the oxygen at 200 g/s. I'd expect the diamond to get in equilibrium before it passes the first row of the radiator. Maybe material with greater heat capacity might be better for the task with this setup, such as Dirt or Polluted Ice.

Personally though I believe the best solution for oxygen condensing is using aquatuner and pool of liquid oxygen. Sure, you need to create that initial liquid oxygen somehow but then you're set and the aquatuner is way more power and time efficient at keeping the machine running.

I did try using an aqua tuner to cool the LOX before storing it into the tank on the left but often the LOX would freeze in the pipes.

Currently the diamond radiator as been running for over 100 cycles and the LOX stored in the tank is -200C

@Neotuck

I think kasuha is onto something. I too think efficiency wise 200g/s seem on the low end for the size it has and the 4! Regulators

Something's gobbling up your cold I think. Are all walls abysalite?

What about plastic?

all insulated tiles are abysslite

and the 200g/s is mainly due to the PO2 source (vent + 20 morbs) I did add extra PO2 with debug mode and it speed up the LOX production

Ah. Yes, of course didn't think of that. Thx

This vids a little old now (a lot of changes since September!) - but the final build is still one of my favourites

Liquid oxygen is only liquid within -218 C to -183 C - that's 35 C range, tight but safe for aquatuner. You can simply have a pump in the liquid oxygen pool and a temp switch right next to it, activating the aquatuner when the oxygen is warmer than e.g. -190 C. That's pretty safe margin to prevent it evaporating and not risking broken pipes.

Single aquatuner can condense about 400 g/s of polluted oxygen from initial 150 C (assuming heat exchange is fast enough), more if the polluted oxygen starts colder.

the LOX in my setup starts at -200C average (as seen in the picture below) I think the diamonds from the rails is the reason the temp drops so much after getting condensed from -50C PO2

well dang, I already have another LOX almost entirely built with things I'm trying out and of course I see ideas in your build that I really really want to try.  LOL   Great layout, love that you give all the overlays and the automation settings, very clear.  Thanks for posting!

Is that the one with three aquatuners?  Do you have a screenshot saved of it?

[NanoD]

hmm.. maybe cooling down the morbs to -200. 

Instant LOX

I may be missing something obvious here, but why does that even work? There is nothing that destroys heat in this design and several things that generate heat. Is this bug-using or is this just very slow to heat up and gives the appearance of working?

[Kabrute]

the water that leaves the pool runs through an aquatuner buried in more than 2 layers deep of the same liquid, this destroys heat because no liquid can be warmer than the liquid above it, after 2 layers deep it deletes heat.  That cold creation is then spread from the water directly into the hydrogen which in turn dumps it into the diamond rail.

so yeah, a borgcube grown into a loxinator would be a fair description

and that same description could very well apply to my own works.

As for heat generation, private testing shows that regulators and tuners do not create any heat and tuners for sure delete a few watts of heat per second from general running across a variety of atmospheres even pure gas with sealed piping, no drippage, in an abysalite vault, the tuner deleted heat over time.

I made an alternative to the borg cube by having heat transfer between a mech door automated with a temp sensor.  Seems to be working well so far

does that no longer exist as a part of your structure?

ya I removed the aqua tuner, didn't seem necessary anymore 

[Kabrute]

are you still using regulators?

at a certain point, call it critical mass, if you are properly keeping all of your cold within your system you can "recycle" that cold almost infinitely
