[Help] What to do with high pressure?

[hyperian]

i'm on my 3rd try at about 110 cycles in with 11 dupes. I'm in a map with limited clean water so I had to start a natural gas/fertilizer combo to run a liquid tepidizer to clean my water.

But in doing so i am creating a lot of CO2. I am pushing it to the outside of my base but it's getting to be around 2kg and I haven't gotten down to the petrolum level to make plastic.

What are my options when dealing with or limiting pressure buildup, without access to high pressure vent? What should i do when I can't easily access new water source and water geyser?

for gas pressures you can use water logged vent for super pressure chamber, or use doors for compression

If carbon dioxide the problem, carbon skinmer will remove it all easy. Otherwise, do closing pressure doors still delete gas? Build a narrow passage filled with doors, hooked to an automatian wire and a clock timer. Have the doors open most of the day to fill the passage with gas and then have them all close briefly and then reopen. The passage should be a vacuum now

Wait what in the what now?

how do water logging vents and door for  compression work?

Those are essentially exploits that can be used to overpressurize rooms.

But you have 2 problems you want to solve: You have CO2 buildup and you have a clean water shortage.

To solve the first, you need convert CO2, clean water and 120W power into polluted water with the carbon skimmer. It only uses minimal amounts of water. If you found a steam geyser then use that water instead of cool water, as the skimmer has a fixed heat output of 40°C polluted water.

To solve the second you want to build a water sieve convert polluted water into clean water. You won't be needing a tepidizer. There are plenty of polluted water puddles in slime biomes that are germ free and there is plenty of ice and snow in ice biomes. The sieve has a fixed heat output of 40°C, which is ok-ish for sanitation in the short to mid term.

However depending on what you want to do with the clean water you have to cool it, especially for food irrigation. Since you don't have a powerplant in place yet, you should dig into ice. Then store ice and snow in your water tank. I recommend you use storage and put the limit to about 1-5kg or so and set it on a high enough priority so your dupes will regularly fill it until you have the temperature and mass you need.

After you done these things you have plenty enough time to set up a powerplant and look for sustainable cooling and filtering solutions.

You essentially build the vent such that it is semi submerged in water - only a minimal amount - such that the tile the vent is in reads as if it's water and not o2 or some other gas. The weight of gas or liquid pressure is checked by the vent - so long as the weight is lower than the vent max  pressure, it will release gas.

I've been expediting the melt process by building ice sculptures over my water basin, lol.

I like to do that too. You can also build them under water.

I have water sieve that i use to convert polluted water with food poisoning into clean water with food poisoning. I use that water to irrigate my food production. food poisoned water seems to spread if i use it for anything other than food production. I do see polluted water in slime biomes but I am scared to get into them because of slimelung. I have no idea how to keep my dupe safe.

What do you mean store ice and snow in water tank? put a storage container inside a water tank and it will cool down the surrounding?

The best solution is to use atmo suits. Alternatively you can dig tight corridors and use deodorizers to clean the polluted oxygen into clean oxygen. Slimelung dies on clean oxygen over time. If you do it carefully your duplicants will only get a bit of slimelung, which their natural immunity can handle. Just check the "Vitals" tab now and then and use airlocks to manage the exposure. If their immunity goes to 0% they get sick and you have to treat them in your med bay.

The ice and snow in the storage will melt over time and cool down your water tank. If you put a standard storage full of ice/snow it will take a long time so cap the storage at a few kg.

You can also build ice sculptures on top of your tank or in your tank, they are built out of 400kg of ice and have a big surface area.

don't i need plastics to get to atmo suits? i don't have access to plastics. 

Is there any other way to use water with food poisoning, other than growing food? because i made a water tepidizer but it sucks up so much power and i have to manually boil batches of water at a time. And then I have a problem cooling the water down afterwards.

In maps with limited water, should i forgo showers because grim isn't a big deal and also forgo lavatory and micro musher since they use water?

Note that for most things you don't need cool water. Only food irrigation and sanitation are temperature sensitive. For electrolyzers, carbon skimmers, super computer etc. you can use hot water directly from a steam geyser or from your boiling setup. The amount of cool water you use is very small in comparison.

To produce atmo suits you only need reed fiber and copper. For the whole infrastructure you also need refined metal.

I highly recommend using atmo suits whenever you can afford to get them. It makes expanding your base much safer and easier at a small cost. It also greatly reduces stress because your duplicants can constantly breathe in them. They are protected from heat and cold as well. They also don't get the "sopping wet" debuff when traveling through liquids, which is very useful if you seal off your base with water locks.
