oxygen purifier with crude oil radiator is amazing!

[manu_x32]

In anticipation of the new oil update, I tried doing a simple oxygen purifier with a crude oil radiator and it's simply amazing the throughput a small device like the one below can output at a very low energy cost once the room is cold enough. It can generate more than 1Kg of liquid oxygen per second with only two po2 pumps running full time and 1 aqua tuner starting once in a while, not sure how often yet, but less than once per cycle for a few seconds. Crude oil warms slowly in the pipes and liquid o2 helps keeping the cooling chamber and the pipes cold.

It's finally possible to do reliable liquid radiators where pipes don't break because crude oil has it's freezing point at -273.2 C and it's evaporation point at 399.9  (given numbers don't change in the update), so it doesn't easily change state in the pipes, which would normally break them, like with liquid 02.

Here's my first draft of such a device. Been fooling around with lots of types of oxygen purifiers recently in debug mode. Seems like this type will be the new go-to solution...

The device is using a closed-loop radiator with a bypass for the aqua tuner for when it's not running, so liquid keeps circulating.You don't actually need 2 aqua tuners, I used 2 to prime it faster, but I ended up closing one of them after only 1 cycle, it was already getting too cold in the pipes.

EDIT: adding small video of the system in action and save file that contains all sorts of oxygen purifier prototype devices, using different types of cooling systems.

They haven't changed the boiling/freezing temperature, but they did nerf the specific heat from 10 to 2...  but it's still higher than liquid oxygen, making it the best liquid for aquatuner below polluted water's freezing point.

Compare power of hydrogen loop 240w vs crude oil loop 1200w, which one giving more LOX ratio better vs production speed per cycle?

Crude oil loop should be better (theoretically speaking) in both the power efficiency and production speed.

On one hand this is good news for aquatuner shenanigans, on the other hand the nonexistent freezing point makes no sense at all... -273.2 is absolute zero, I wonder if the game still crashes if you get crude oil that low in the aquatuner.

The lowest regulators and aquatuners can get to, if I remember correctly, is 5K

Technically, crude oil doesn't have a specific freezing point. However, it does have a pour point below which it becomes plastic and therefore impossible to pour or pipe therefore by all intend and purposes for this game the same as a solid. This is usually between -32C and -57C. I too find crude oil ridiculously overpowered as it for all practical purposes have no freezing point in the game, and an evaporation point of about 400C. That's a astounding range. Then again, we have abyssalite in the game and are fine with that being totally unrealistic. I guess it just the suspension of disbelief that gets ticked off by it being named after a real world substance with quite different physical properties. Should have called it deamium or sorcerium or something just to keep the fantasy feel the properties imply.

Isn't that just because that's when hydrogen solidifies so there's no substance that could go lower? I remember the game used to crash when you froze something to below absolute zero before pipes took damage for state change in them.

I dont think ill use this on longer run, since the oil freezing point and boil point is just random number they put in my opinion. In reality check the crude oil formed by many component ,  and their shape is like gel, fast research at google i found they become solid around -50c athou not sure which oil they talking about.

I think they will balance the number when they add more interaction with subtance like flameable stuff. If they keep this number for the sake gameplay, it will be broken and overpower, like mealwood OU

If you really want a broken liquid, use Naphtha. It has no state change at all. 2.191 SHC. 0.2 TC.

Just melt plastic. I expect this to be patched real quick.

What about cooling with liquid hydrogen? You can liquefy the first batch with oil.

[Sevio]

@Kasuha Liquid Hydrogen's temperature range is pretty small, smaller than the 14 degrees C it would be cooled down by in an Aquatuner, so if it's possible at all I doubt it would be practical.

Oh, okay. I was trying to check that but the game crashed on me every time I tried it.

I wonder if they'll patch the oil, though. According to what I have found...

Quote

... it is impossible to refer to a common freezing point for a crude oil because the individual compounds solidify at different temperatures. However, the pour point—the temperature below which crude oil becomes plastic and will not flow—is important to recovery and transport and is always determined. Pour points range from 32 °C to below −57 °C (90 °F to below −70 °F)."

so it's rather high compared to liquid oxygen.

[Sevio]

Hydrogen's vaporization point is -252.2 C and its freeze point is -259.2 C, so only a 7 degree range . Even with the leeway of a few degrees with state changes, it might already be very difficult just to liquefy it without accidentally solidifying it, let alone use it as a cooling medium. Maybe that difficulty will be rewarded some day if we get to combine liquid hydrogen and liquid oxygen into an extremely powerful (read: explosive) rocket fuel.

That quote is pretty much what I wrote above about real life crude oil being completely different to the in game crude oil.

Good to know, thanks!  I guess there's no point calculating numbers currently then. And I don't want to try the update yet, it's apparently very buggy and debug mode doesn't work well.

adding small video and save file in initial post in case anyone is interested in seeing a bunch of different prototypes.
