Help with PW offgassing and ceramic


Recommended Posts

Hello, I'm trying to "mass" produce ceramic and would like to know if what I've built makes sense:

Do mesh tiles help or hinder PW offgassing?
Would it help if I put airflow tiles underneath the PW?
Any suggestion to make this faster? Or any better compact design?

I've read about offgassing a bit but some details to understand it are missing!

the amount of off-gas is dictated by the water "pressure". 

 

If you use the gas lock infinite storage solution, you can have only 5-10 tiles with pw, but at pressures well above the regular 1t. 

 

This is most likely be the most space / material efficient way.

The wiki states that having more that 1t liquid in the top tile doesn't make a difference, is that outdated?

Sadly wiki is sometimes wrong. the off-gassing mechanic has always been bound to amount in the tiles. afaik atleast :)

If you want to make high-density PW bottles for off-gassing, without much dupe labor, then build a liquid reservoir.  When its full, deconstruct it.  Build it again.  Repeat several times.  Any time you need to replace the bottles, build another reservoir again.  The only dupe labor is spent in building and deconstructing.

There's also a thread somewhere that someone built an automated system for using a bottle pump and a bottle emptier to make a dupe continually fill bottles with water, then drop them.   In this case, once built, it only takes dupe labor when you need more bottles.

Here's a more space efficient way that doesn't use labor, automation, or mix gasses. Off gassing in this way eliminates germs from the PO2 due to a probably unreported bug. Top vent puts out 0.1g/s to instantly vacuum the off gassing room (up to 1000kg/tile in the output room) and the bottom vent (location of brine) is where you put all your PW.

Interesting, I just learned something new about ONI physics 

I think it's been like this for a really long time? Like, the oil in the oil biome is very frequently overpressurized and if it weren't for the tile limit, the entire biome would've been swept by the oilnami. 

Incidentally, do tiles broken with pressure drop the full mass or just half? For all I know they could not drop anything to begin with...

@suxkar As already said by others, I suggest you to bottle the pwater. Offgasing is a looot more important this way.

Here's my setup, if it cans bring you ideas. Just note I'm working in a full vacuum world (world gen mod : Emptera) so I don't bother with evacuating O2, I just vent it in space using atmo sensors & doors.

But the bottling machine, relying on the mopping errand, and highly based on @Yunru 's setups (the great MOGOM series) is working pretty well I must say.

Valves are 2500g/s.

Filter gate is 6sec.

Liquid sensor on the mopping tile below 120kg.

The one below, close to the pump, is just to avoid the machine pumping tiny packets (so above 50kg).

Atmo sensors below (next to the pH2O are 1100g/s. Only one atmo where the bottle is should be enough, instead of what I've done here.

Atmo sensors above are 800g/s.

 

There's nothing special with conveyor system. Bring in rego, take out clay. I've prepared the ground but didn't reach this point yet (for rego).

Hope it helps !

 

I never tried offgasing in a larger scale, but read it is the most efficient way to get oxygen. 
I will get 100 % the mass in polluted oxygen, right? If I cool that to LOX and heat it later I will get 100% fresh oxygen plus a small amount of dirt?

That means I will have an11% bonus over Electrolyzers, but will not get any hydrogen. Is that it or did I miss anything?
Can I scale this to bring me some 5-10 kg/s without dupe time? Energy does not matter...

Half mass for natural tiles and farm tiles, no mass for constructed tiles.

Funny thing: broken farm tiles can then be deconstructed for the full mass. So you can generate 50kg of dirt/copper each time you do this.

Due to scaling, storing all of your PW in one cell for no labor germ free off gassing will be as fast as you need, once you reach a critical mass. 12T/cycle? No problem.

Yes.

No dirt.

Thanks everyone for the meaningful suggestions! I will put them to good use.

 @nakomaru I'm not sure I understand your design, what is the vent in the middle-left outputting? I've read that deodorizers have 2 tiles radius, is that the reason for the crude oil layer? They basically automatically sort O2 and PO between rooms?

Yes. You can have a deoderizer built on a mesh tile.  Beneath that you have an airflow tile.  On the mesh tile is some liquid and of course the airflow tile is in an atmosphere of whatever you're wanting to process.  For example, PO2 in the room below can't go up through the mesh tile because the liquid is in the way.  However, the deoderizer can reach the PO2 that is in the airflow tile, and pulls it through to process it.  In this way you can have your dupe accessible room completely isolated from your contaminated air and still process everything.

0.1g/s of any liquid lighter than crude oil. This swaps places with the tile to the diagonal bottom left of it. Then it destroys itself. (falling liquid tiles 10g or less destroy themselves after falling one tile)

It is used to vacuum out the evaporation chamber nearly instantly. (PW won't offgas above about 1800g)

You need to provide a loop back with a bridge in case the PO2 room reaches >1T per tile, so it doesn't ever accumulate to more than 10g, or you will start pouring the water in the room.
