Why? Is it dangerous? Toxic? Very volatile?

 

Would you just recommend Acetylene?

 

 

all of the above basicly.

Ethyne is fine, although not frequently occuring

How about these sorts of quantities of gases in the atmosphere?

• Methane - 36%
  
• Ethane - 7%
  
• Chlorine - 2%
  
• Acetylene/Ethyne - 6%
  
• Phosphine - 0.5%
  
• Argon - 3.5%
  
• Hydrogen - 2%
  
• Helium - 3%
  
• Nitrogen - 40%
  

 

I'm guessing this is going to be a very light atmosphere

Argon, helium, nitrogen are always safe bets

 

the antagonist would be the Chlorine and possibly the Phosphine.

Cl and Phosphine still need a bit of reducing me thinks.

 

Looks like an interesting atmosphere to say the least. I'd think it would look pretty cool too - those high enery olar discharges would cause some prrtty colours in the sky... as long as they don't become progressive. Then again they don't on Jupiter so

 

What type of planet would this be, size, composition etc. From the looks of that list it would probably have seas of liquid methane and nitrogen!

What would you suggest to keep it safe? I need chlorine to be my oxidiser don't I? And I can always leave Phosphine out.

 

In reply to #29:

The planet is supposed to be around the same size as Earth, maybe smaller, maybe bigger. The organic compound I am using instead of water is something called Tetrahydrofuran. I want there to be seas of this on most probably a silica (sandy) landscape. I am really hoping none of this will conflict. The temperature is going to be around -60 degrees celcius.

Keep then just reduce the values. If its very cold though then the values need to be reduced a little to make it reasonable

 

Wish we had some astrophysicists here... maybe they would be more help.

Would 1% chlorine and 0.2% Phosphine work? Or maybe a little less on the chlorine.

All I will do is add a little onto nitrogen to make up the differnence.

Sounds good to me but I am no expert so I can'ty say for shure it would work - your allowed some creative leway I believe

Excellent. Thats what I will do.

Ill make Chlorine 1% (so fire can still exist)

Phosphine will be 0.2%

And so Nitrogen will be 41.3%

 

So the final list is:

Methane - 36%

Ethane - 7%

Chlorine - 1%

Acetylene/Ethyne - 6%

Phosphine - 0.2%

Argon - 3.5%

Hydrogen - 2%

Helium - 3%

Nitrogen - 41.3%

 

Thank you very much all for the effort you have put in and the info given. It has really helped me. Now I know that fire can exist and I have the knowledge of how to get it to happen. Thanks.
