Priming the system

 

Bridgework makes priming simpler.

To be honest this is complete and total overkill but here we are.

Each circuit is 1920 watts, roughly, as such I've put 1800 watts of coal on each to allow for 85% uptime, at most it should be running 30% but getting it down to temp I tend to run it "hot" to get it started.

I'm using a combination of liquid cooling (petroleum loops) and weeze cooling.  Temp Shift Plates are made of igneous, metal rail is made of gold (thank you gold volcano) "tiles" are abysallite.  I will be using doors for insertion and extraction pressure regulation.
Secondary Cooling system

 

By utilizing throttling nothing runs 100%.  based on previous tests each aquatuner can handle the cooling for the tower by itself "at run speed" however I had to push my aquatuner to 100% before maxing out my thermoregs getting down to temp before, that should solve this problem.

Quality post with great description.

What do you use to cool all the regulators? In hydrogen atmosphere, two Wheezeworts have hard time cooling one regulator and here you have 23 regulators and only 6 worts...?

The over cooled  hydrogen from broken pipes will. (There are liquid pipes behind regulators so I guess that's the cooling plan).

[Kabrute]

I edited the original post to show the cooling system.

[Hakon]

Are you going to use it or not? You don't pump in poluted Oxygen. And how does the automation look like? Maybe you can ad the automation overlay.

[Lifegrow]

I'm guessing - but I assume switches submerged in LOX in the central cavity (between the normal/metal tiles) and thermo switches to each "band" of cooling regulators. It won't work very well if that is the case - so i'm hoping i'm wrong.

[Kabrute]

can't start converting till all rails are primed and since I was using my hydrogen for power its been a bit of a slow process.  As for automation, there isn't much right now except on doors or for shut-offs/bypasses most of which are shown.  I'm using valves to regulate flow-rate in the radiator lines thus controlling their temps with flow-rate instead of automation.  In prior trials using 2 regulators on bottom floor allows me to set a flow rate of 75 g/s without having to worry about pipe breakages etc.  For the upper floors I've traditionally had to run 2 regulators per floor at over 300 g/s just to steer the temps down on the kinds of pressure liquid manipulation requires.  Once the system starts using the pumps though the majority of the coolant system comes from the aquatuners tied to the Lox itself.  Since these values will need adjusting over time, valves give me the means of responding.  Based on previous experimentation this system should reliably convert +10kg/s at a constant, even involving pressures beyond 100kg/cell in the PO2 side.
@lifegrow its not running full bore 1kg/s through each thermoloop so it doesn't need instant shutoffs.  Exact valve values will be given once I have the system on line, for now its still priming

the goal is to slam the po2 down to temp, get it converting, then switch cooling from air to liquid driven cooling

Addendum: Max throughput is 20kg/s

[Neotuck]

What's your PO2 source? 20Kg/s seems like a lot

[Kabrute]

PH2O, morbs, slime carving, pdirt offgassing.  20kg/s is Max, not what I can supply it but what it is the maximum throughput as set by 2 liquid pumps.  Theoretical limit more than an actual one, the limit of the machine will be announced once up am running though to be honest its throughput limit is probably going to be how much PO2 I can actively produce.

I don't think the two pumps are the bottleneck. Might be interesting to see what throughput you reach in practice.

@Kabrute

Now that's a real behemoth! Good job!

I have a few questions. 

Do you use the liquid o2 inside a heat exchanger to precool the po2? If not then do you think using the l-o2 with an aquatuner would be a good(better or smaller) radiator to cool down the p-o2 either close to condensation and then use the h2 or even as an lo2 maker on it's own? Since liquid radiator transports more heat/cold than gas radiators.

Cheers.

Edit. Scratch my questions. I didn't saw the end of your 2nd last post:D

[Neotuck]

@Kabrute what about dripping the Lox on the top regulators and letting the super cold O2 heat up on the way down?

[storm6436]

It's a damn good thing they don't model LOX like the real thing.  Suggesting industrial chilling via LOX would get you some saucer-sized eyes and more than a few nervous laughs from the chem, engineering, and physicist types in real life.  To be fair, some of us do like a "Hold my beer and watch this" type of challenge though.

! Food shortage

! Insufficient oxygen generation

I wonder how many dupes died building this monstrosity?

[Kabrute]

0Antigravity System.sav

I completely wiped out my farm for 70 cycles waiting for my geyser to start back up, thats why I ran out of food, I tapped an extra geyser though and have rebuilt the farm, all is well now.

the "Insufficient Oxygen" is a side effect of vapor locking the asteroid :2k pressure everywhere, lots of oxygen: and dupes breathing in stray PO2 that offgasses without getting counted as production.

[Kabrute]

the little dots means its working.  The "Flow control" below is for a gas valve above

If you plan things too well you will vapor lock your system and have to pull some fluid from it.  The easiest way is to break and rebuild a single section of piping, you get a small spill as seen above but otherwise no big deal. 

I have 8 floors of thermal exchange at an average of 50g/s/floor so roughly 400g/s total gas flow across all floors, so the aquatuners are set to 400/350/300.

Real Power usage is less than 2 spoms and actively dropping temp, and maintaining cooling towers temp. 

This build relies heavily on the thermal inertia of liquids to maintain cooling capacity at higher throttles.  I'm going to shut the machine down now and extend the thermal transfer rail because it is showing only 1c difference per square so I'm thinking it needs stretching.
I'm also going to include shipment systems in the extension build to deliver slime to a door compressor room for converting it safely to PO2 before injecting into the cooling tower.

I thought I'd share my pO2 Cooler, it's not nearly as impressive, and I have no idea howmuch pO2 it can theoreticly cool, but it's keeping up with a hot pO2 geyser easily, so I'm considering to add in more gas from a morb farm.

The three thermo regulators cool down the hydrogen going through the pipes, doing the initial cooling, then when the -160C pO2 comes at the bottom, the liquid O2 I pump around through an aquatuner to keep it under 200 degrees, and the diamond heat plates there do the rest.
A thermo sensor top right ensures that the hydrogen doesn't get too cold, while a thermo sensor in the liquid O2 ensures the liquid O2 doesn't freeze.
Currently, I use the pressure from the geyers waay above to push the pO2 into this area, but some door compressors might be needed to increase the flow.

I'm curious though, how do you make your morbs produce so much pO2, I have like 40 of them a little further down, and I pump all the pO2 they make into the room bottom right where I have 4 pufts, but they seem to be barely keeping up with those 4 pufts, what am I missing? should I give them more room to run around in or something?

[Kabrute]

the only reason to feed the po2 from morbs to pufts is for mushroom farming, else straight from morbs to initial cooling system.  Need to replace your gas pump with a valve and find a way to integrate heating up your Lox with cooling your PO2, the entire purpose of the metal rail in my build is to transfer the cold from the Lox to the Po2 using "Counter Current Exchange" instead of TSPs and to extract Pure o2 at as near room temperature as possible.  Your build looks likely to be limited by cooling/heating more than anything else, IMO, and no way to readily extract your O2 o.o.  As for your morbs output, "suck the breath right out of their lungs" to quote what someone told me my first week in the forum, otherwise I got nothin.

[suicide commando]

Oh, I know, currently I'm just building up my liquid O2 supply, I plan on extracting it from there eventually, I have an iron volcano and an oil well close to eachother waaay down in the oil biome, I plan on cooking oil from the well with the volcano, turn it into NG for a zillion watts of power.

After the NG has then given some of it's heat to a steam turbine I plan on running down there as well, I'm going to mix it with the liquid O2 to cool it down to managable levels, then pump the normal temp O2 into my base and the managable NG into the NG generators that will be installed there for that zillion watts of power.

As for sucking the breath out of their lungs, I believe the general pressure in that room is about 100g or so, due to a pump above them sucking up all their pO2 and pumping it into the puft room. And yes, those pufts are for mushroom farming.
I still need to install autosweeping there too.

Soo much to do...

[Kabrute]

I'm planning a similar oil system with the steam plopped down at the 210C section of the oil cooker  and thanks to finding out about pumps working partially submerged, combined with liquid temp locking with temp shift plates, you can pump gas at rediculous temperatures, way beyond normal gas pump ranges.

[Kabrute]

For now I've decided to switch the system from coal to hydrogen with coal as a backup, thusly

 

Based on reports the tower as a whole pulls less power than 2 spom so hydrogen is feasible as a power alternative and if the battery takes to long to charge the coal gene kicks in.

and extend the rail as indicated earlier

 

I'm preparing a 5 door compressor for the injection chamber.  That "volcano" is a cool co2 so I mainly just ignore it.

though trash did accumulate in the bottom of the silo while remodelling, a quick decon-recon of the bottom fixed that up.

[Kabrute]

system rushed down to temp without hardly budging the "hot"side.

 

Ran valves at 140 g/s for 4 cycles before having to back them off, now averaging 40g/s/line 
Combined with the bypass I installed in the liquid coolers because I needed the cold circulated but don't need more cold added.





 

Lastly, I don't know if its because I built it out of all Gold(probably is) but the rail isn't long enough even with the extension

and I've still got to drop another 40c, the struggle is real 
modified my doors to provide thermal buffering
