What sabatier means?

[alphaprior]

I've built a space station one of the modules PXL-2 Shelter Deep Space Module has an option to "Start Sabatier", what the hell means that? I googled for it no translation makes sense in the game. Someone can explain/translate this to me?

Presumably it's referring to the Sabatier reaction, which produces methane and water from carbon dioxide and hydrogen.  It's a theoretical way to get rid of built-up carbon dioxide while also producing more useful products (methane can be used as a fuel, and water has obvious uses).  I know a few different life support mods have a Sabatier Recycler unit for that purpose, including TAC Life Support.

Hmm ok thanx! There is also Carbon Extractor, Water Purifier and WaterSplitter, so sabatier is another chemical process.

Those are all TAC Life Support parts, and yes, they're all chemical processors that convert life support waste products back into usable life support products.

wait  a moment, since those things also exhist in kerbalism; what's the difference between TAC life support and kerbalism life support?

I've used neither of them but I'm pretty sure TAC doesn't have all of the fancy radiation and Kerbal health stuff.

TAC, Kerbalism, and iirc USI Life Support provide several independent implementations of the life support equipment. Choose any or none.

Irl a Sabatier reactor is used in the "American" part of ISS to convert carbon dioxide into methane and vent it away.
In both ISS parts ("American" and "Russian") they use electrolysis to extract oxygen from storable water for breathing.

On Mars they (Zubrin, Musk, etc) plan to use the Sabatier reaction to produce liquid methane, from local carbon dioxide and imported or ice water, as fuel to return home.
KSPI-E mod has a methalox engine and some limited ability of the methane processing.

This discussion of modded parts has been moved to the modding sub to avoid confusion.

I'm a TAC user. TAC is a Kerbalism with less realism and TAC isn't as hard as Kerablism.
