how can i reduce the gas pressure inside my base?

[Black Dee]

my gas ducts are stoping because the high presure inside the rooms, how can i reduce it? i already have a giant room to keep this gases insideit but it´s not beeing enogth... now my natural gas power plant is stoping because this high pressure issue.

to keep natural gas generators going, throw an air scrubber near the co2 vent
have a puft cage and direct excess polluted oxygen to it, these blobs can devour metric tonnes of gas in few cycles. have a hydrogen generator at the top of your base to drink up the hydrogen buildup, and all you're left with is a balanced proper oxygen production

i use a mutli-pump circulation system, moving the gases around in a circuit, while filtering out the ones i don't want into rooms with scrubbers or purifiers.

it's reasonably effective.

The ultimate answer is to find a Void to dump gases too, but not every map has one. Otherwise, as people above said, utilize the machines that output less gas than they consume, such as CO2 scrubbers, algae terrariums, and hydrogen generators. Another (temporary) solution is to dig out a larger area, every excavated tile will need to fill with gas which will lower pressure in adjacent tiles until they are equalized. Just be careful when digging into polluted oxygen pockets, as they sometimes have pressure in the hundreds of kilograms per tile (due to the "bug" that you can take advantage of that I describe below)

Wheezeworts can also be used to create low pressure areas, as they draw in gas at the bottom of the plant and expel it at the top, and they can't "overpressure". So you can get creative and create a chamber with wheezeworts that draw gas out of it and expel it above, and then put your exhaust vent in that room.

Finally, there is also a possible "bug" that you could take advantage of. If your gas vent is built in a tile that has less than 1800 grams of liquid in it, it will not register as overpressured even if surrounding tiles have massive amounts of pressure. Build a flat surface a couple of tiles long, but blocker tiles on each end, and pump a few hundred grams of water into it. Build the vent there, right in the water tile, and you can dump unlimited gas with no regards to pressure. This may be an unintended interaction by the devs, but it takes advantage of the fact that only one "element" can occupy a tile at any one time and the vents do not discriminate between liquid or gas pressure when they read the outlet pressure.

is it like creating your own "void"?

[merccobb]

Not a void, because the gas will still exist. The gas will not be able to occupy the same tile as the water, but can merge with an adjacent gas tile even if the pressure is already very high. So you can create your own extremely high pressure tiles, similar to the pockets of polluted oxygen you can sometimes find that have hundreds of kg of pressure per tile

oooh ♥♥♥♥ so pufts devour polluted gas? well there you go man. I see the cycle now.

Now if I only had sand.

create steam from polluted water using the tepidizer. for some reason, it randomly spawns sand blocks. :)

If you can find Pufts and capture them. No idea how to capture critters.

[merccobb]

Pufts are difficult to wrangle, but with some persistence you can herd them into a useful area. They are very delicate though, you especially need to be careful around any falling water as they will fly through it and drown themselves very often.
