gas vent overpressurized

[Melonchief]

what should i do when it says gas vent over pressurized?

[Pusteblume!]

move the outlet to a place were the pressure is lower.

[Zervo⭐]

built a gas valve to lower the pressure.
and the last time i tried, you need to rebuilt the vent.
don't know if this is intended or a bug.

You need to depresurize room with vent. For example suck out other gas (CO2 or something). Or make better flow possible (with more space or improved tales which would let gas go through them).

I have a gas pressure of about 50g on the vent, it still says it's overpressured

I still dont get how this works... In my games, it doesnt matter how far or close the vents are to the pump. Do I need to use pressure locks everywhere?

[BladesAndRazors]

So what's up with this vents? My also get overpressurized although i use a valve.
Where should the pressure go in a closed habitat like this asteroid?
Can anybody please explain how to use them?

Vacating a tile of whatever is in it creates a vacuum. That's one way to lessen pressure. Just chop out a new area.

However with things like slime that belch out PO2, at a ludicrous rate, you won't get much benefit from chopping out the area unless you also remove all that slime a.s.a.p. It will mostly generate PO2 as fast as you're clearing things, so in an emergency with an overpressurized vent it won't help much in the immediate sense.

If you have the ability to use up some of the things you want to get rid of, that will certainly help. Maybe the area you want to vent into already has some CO2 in it, for instance. Throw a scrubber up there. That will lessen the pressure, and free up space for new gases to fill in. Or maybe there's hydrogen floating around in the upper regions. There usually is after a while. Throw a pump up there and take advantage of it. Suck out the hyrdrogen, and you may be able to simply vent the PO2 right back into the same room, since you'll be removing some pressure by drawing off the hydrogen and using it to power things.

I do something very similar with my main base. There's a hydrogen pumping system at the top, and a series of filters. The first sends the hyrdrogen to the generator. The next filter sends any pure O2 it sucks up back down to the bottom of the base where I can use it for other things. The last filter grabs anything that might be left, bits of PO2 or whatever, and vents it off into another area.

The thing is that the longer it all goes on the more Rube Goldberg-y it all gets, and you find yourself building a new subsytem simply to be able to clear out another place in which you're eventually going to have to also build a new subsystem and on and on it never stops until you run out of certain resources entirely. But if you actually reach that point you'll be pretty bored anyway, and won't care when it all comes to a rattling, choking halt.

When the pressure around the vent is above ~1.5 - 1.8 kg (can't remember exactly) the vent is overpressurized and stops working until the pressure outside is dropping again. Wether that is a bad thing or not depends on the situation. Valves don't really matter, the vents WILLwork again, when they can. When this thread was made there still was an issue with the icon not going away, leading people to believe vents were totally borked.

If it's your oxygen distribution, well great you got enough O2, nothing to worry about. Maybe build more vents across a bigger area if you don't have your whole base filled up with O2 yet.

If it's the CO2 vent that's supposed to vent the gas generator's exhaust, that's more of problem. Build more scrubbers, excavate more, move the CO2 room to location thats better suited... It's pretty hard to give a general solution, this really depends on the particular situation.

Or, you can space out your gas vents about 10 tiles apart, and they will fill the room with whatever gas you are pumping.

You can also strategically place gas permeable tiles. Light gases move up and to the left (oxygen for example), heavy gases move down and to the right (co2)

In my power generator room (huge, with five levels, 35 tiles long each level), I have gas/liquid permeable floors. The lowest level collects polluted water, has a pump there to suck out dirty water to irrigate plants and for water purification.

Level two contains an algie terrarium, a co2 scrubber, and three natural gas generators.

Level three contains algie terrarium, a co2 scrubber, and three coal generators.

Level four and five contain batteries and power transformers.

Up at the very top left corner is a gas pump with some gas filters to filter out oxygen, and pump it throughout the base. At the level two and three are algie terrariums to recycle CO2 into oxygen. I also have one CO2 scrubber at level two and three, when algie terraruims can't keep up with CO2 production. This set up works great.

The problem is that your base is full of gas. There is no room for more gas. The vent is trying to "push" the gas into the room, but the room is full. Thus, there is too much air pressure and the vent is "over-pressured."

But wait, you say, I need oxygen! How can I make more oxygen if my base is totally pressurized?

The answer is that your base is filled with too many non-oxygen gasses. You need to remove unwanted gas to releave the pressure. You can build hydrogen generators to remove hydrogen. You can build CO2 scrubbers or algae terrariums to remove CO2. Once those gasses are gone, the pressure will be lowered, and there will be room for more oxygen.

Hey thank you all.
Sadly it's my Natural Gas generators stopping because of CO2 output pipe is clogging.

So i need to dig more.
Has the game some sense of air pressure so the air gets thinner in the upper area? May this help?

Some players posted pictures of voids but i found none on my map.
This would solve all overpressure problems.

If the coal generators would burn (polluted) oxygen there would be some air flow...

So let*s see what the next updates will bring.

You need air scrubbers to remove the CO2, everything else is just a stopgap measure.

can only run 4 gens per vent
set the scrubbers up under the vent outlets like this

I had that issue as well. Natural gas generators absolutely need a couple of support systems to operate properly (they are an unlimite energy source and therefor worth the trouble). Just digging out mire room for the CO2 will at best delay the colapse a bit, but it won't solve your issue. You rly need to get rid of that CO2 a lot more effectively. There are a couple of solutions for this, but many of them take large, complex setups (like freezing the stuff into a solid) and you usually don't have that time when your main power supply is about to fail.

The best option for the moment is almost certainly to build one or two air scrubbers. They are easy to set up and it buys you a lot more time to fix the next issues.
Keep in mind that they do consume some more of your water and sand. And you'll also have to deal with poluted water. But those issues are manageable and more importantly, they are unlikely to wipe out your base over night. CO2 overpressure on the other hand often gets critical very quickly.

[Generalkoko]

could always super cool Hydrogen and turn the materials Solid that should solve that issue xD
just freeze the co2 into pellets and leave it in a super cooled room.
