Oxygen is extracted from sea water while taking sea water on board for potable uses and for reactor cooling purposes. CO2 is extracted from the boat's atmosphere by CO2 Scrubbers and released overboard. CAMS is a constant test of boat atmosphere for CO2 and other gases which helps to prove and diagnose the atmosphere throughout the boat. GO NAVY

“Yea this eog, it uses water and KOH” and now they didn't like me saying that so it's “shut down” and we must “burn candles”. Pons an fleshman, 1980, university of Utah, star in a jar. Cold fusion is easier with distilled water supplemented with KOH

The miniature nuclear submarine NR-1, in service from 1969-2008, burned chlorate candles for its oxygen supply. The only reason I know this is because one of my instructors at Navy Nuc Power School in 1979 was a chief who was the engineer on this unique little sub. Quite a career the thing had over those nearly 40 years in service.

Nitrogen generally isn't absorbed during breathing - you exhale the same amount you inhale. That means you don't have to add any significant amount.

We also use CO2 absorbent in the practice of anesthesia. Soda lime is the most common agent to remove CO2 from the breathing circuit so that anesthetic gas can be conserved and lower flows of fresh gas are required. Great job Destin!

When you pump out CO2, you are indirectly losing a certain mass of air. Will it not continuously keep reducing the atmospheric pressure inside the submarine??? Please clarify..
Smilley MLK

Think about where the CO2 is coming from: the people exhaling it. The oxygen is replaced by the methods described, and the carbon comes from the marines' food, essentially.

Very interesting video. The preheater on the CO2 scrubber is probably just a heat exchanger with the returning lean MEA as this will be hot from the boiler and will probably need to be cooled for it to absorb CO2 and also not significantly heat the air passing through the absorber. Rather than have a separate cooler transferring as much of this heat to the rich MEA before it enters the boiler will make the whole process a lot more efficient. This would be my best guess given the process you show and my experience with heat engines.

So they can't make oxygen forever, only until they run out of hydroxide, or candles.
Smilley MLK
Hour ago
Hydroxyde is a catalyst, meaning it is less (ideally) not consumed in the reaction. In practice, both the coal electrodes and the hydroxyde will run out eventually, but the sub will run out of other things - like food - much faster.

Something like those oxygen candles are what eventually killed the survivors of the Kursk sub. They were using them in the last room that still had air, but one got wet and violently reacted, basically turning into a blowtorch instead of a candle.
Dave Wong
4 hours ago
How does burning the candle releases more oxygen then it consumes by burning the candle? The chemical equation doesn't add up. 4Fe+3O2-->2Fe2O3 (consumes 3 moles of oxygen); 2NaClO3--> 2NaCl + 3O2 (release 3 moles of oxygen). Am I missing something?
Smilley MLK
Hour ago
That would only be if they were used in the same quantity. 1 mol of Fe can cause multiple mols of NaClO3 to react.

Interesting video, this makes me wonder why not just get oxygen from CO2 solving both problems at once?
Smilley MLK
57 minutes ago
Because CO2 is a very stable molecule, and both O2 and C-radicals are way too reactive. You couldn't separate them with electrolysis, and chemical separation would have its own issues. Not to mention what to do with the remaining C.
