Gas mixer, unexpected gasses in output

[valenti_scott]

Hello-
I have O2 and H2 being routed into a gas mixer. It is mixing them 67-33.

I confirmed that the two input pipes only contain O2 and H2, using a tablet. The pressure in the output pipe was zero.

I turned on the gas mixer, just for about half a second, not to get much pressure in the output pipe.

Then I found that the output pipe contained a lot of CO2 and X, even though they weren't in the input pipe. Has anyone seen this sort of thing?

yes this is normal, CO2 and pollutants(X) are the result of the combustion of oxygen with hydrogen

[valenti_scott]

Ah, I forgot about that. So I have to make sure the pipes are below a certain temperature? Or I can't mix them (O2 and H2) at all?

[Jericho]

yes, you have to mix them to get the right combustion to be able to melt the ores. Normally if you don't put a huge amount of the mixture, you don't need to lower the temperature and the pressure to avoid the pipes exploding. I melt all my minerals without needing to lower the pressure and temperature. It is necessary to start with not too much mixture then to increase gradually according to the cooking needs. We must do tests...

[Jericho]

you have to think about the right mixing proportions (see wiki)

I looked at the temp of my input pipes (O2/H2), and they were both around 170-180C; so I guess that is the issue. I need to cool them down! (They are reacting and burning because they are so hot?)

These gasses were collected from a furnace in the first place; I guess they are retaining heat from the furnace. I suppose some radiators would help...

[Jericho]

it is above all the pressure that can be dangerous for the pipes. You can use a Back Pressure Regulator Kit out of the oven to lower the pressure. But the problem at the start is that you had to put too much fuel and turn the oven very high in temperature and pressure. I never have this problem because I dose my fuel just according to the needs of each ore melt

[valenti_scott]

I was intentionally collecting H2 and O2 using the furnace (I'm on the Moon), and the gasses were hot as they left the furnace and went into the pipes.

same happens to me.. you gotta keep the output pipe under 30-40c
also its best to mix into a tank with a pump to act as a one way valve. put the tank in vacuum and put a bunch of radiators on it so it stays negative temp.

make sure you have more than 1 pipe between the mixer and the pump.. or it will explode. as the mixer pumps faster than the volume pump.

i really wish the digital valve was one way, but its just a switch. even tho it shows as being one way when you place it.

you are lucky it didnt explode.

[valenti_scott]

OK, so 30c or cooler. I had already had explosions caused by a mixer.

I've learned to give the mixer short "on" bursts, and then check the pressure, and go back to "on" only if the pressure is still low. I also keep a meter on that pipe so I can easily check the pressure.

Why does combustion of O2 and H2 cause pollutants and CO2? I love this game but there is a lot of things that makes it insanely unrealistic and unsensical at times... It should produce H2O only.

you are thinking of fusion not combustion. fusion is joining the atoms and combustion is burning the o2 and h2.

Combusting O2 and H2 produces water, combustion is a chemical reaction between two or more molecules that wants to stick in different ways to eachother. And no im not thinking of fusion. Fusion creates heavier atoms, not molecule bindings. If two hydrogen atoms fused togheter into an heavier element, which normally creates a helium atom. Then THAT is fusion. Which is the opposite of Fission where heavier elements break down into lighter elements, like in a fission nuclear reactor. Combustion on the other hand does not exactly create heavier atoms. It combines two or more different atoms into a molecule chain. Like water for example, which is a binding between hydrogen and oxygen.

That it produces pollutants and Co2 implies an entirely different process. Co2 stands for carbon dioxide its carbon fused with oxygen molecules. That requires chemical reactions between something carbonbased with oxygen. The pollutants would come from additional molecules that would be in said chemical reaction.

H2 and O2 alone doesnt contain carbon. And they combust because hydrogen likes to stick to oxygen. This releases energy in form of heat when they merge into a water molecule (H2O).

If they create Co2 and pollutants then the devs either did this for the sake of game mechanics. Or they confused H2 (hydrogen) with carbon based fuel. If the case that it is carbon based fuel (also NOT H2) then it is more likely Co2 and Pollutants would be the product.

Im guessing its another weird game mechanic related thing since you can combust coal without any oxygen at all to produce energy.

I thought the wrong chemitry is a bug. but I was looking for the wrong chemistry in stationeers and found your post. The pollutants are ok because the melted ores contain bad things.

I think the reasons can be:

1. The developers had a 6 in chemistry.
or
2. The developers dont want a easy peasy loop for: 2 H2 + O2 <-> 2 H2O + energy

I will take a guess and say that the devs are a lot smarter than you(and me), hence why they're making money and we're spending.
