    hahahahaha they don't burn candles! hahahahaha those are for emergency situations! the environmental systems on the subs are MORE than capable of producing all the oxygen (and hydrogen) needed for the coners and the engine room.... i'll just leave it at that... if you're lighting those candles for real.... you're probably in a REAL BAD situation...

    I'm not going to watch the video but just wanted to say that if you run an electrical current threw water from point a to point b you get oxygen bubbles in the center. Now leave this technology to the imagination & you can invent many things to help a human breath under water. You can even create a rebreather under water is done correctly and safely.

    the MEA is turned into a carbonate salt would be my guess. they would probably preheat the carbonate salt to keep it liquid when they put it under pressure so they get a smooth crack of the carbonate back to freebase amine. many amines form carbonate salts that are mostly solid with often low melting points hence the need for preheating so they can be pumped and pressurized. when ethanolamine carbonate is heated to the right temp it will crack the salt allowing the carbon dioxide to leave. this could be over the boiling point of ethanolamine hence the need for the pressure. I would say the ethanolamine was there choice in the least toxic amine to use as some of the other options are not too friendly :) the great thing about using a base like an amine to capture CO2 is that it is a simple acid base reaction to remove the amine from the breathable air that is expelled so I would say the scrubbers are just acid tanks. many amines that are small like this one smell of ammonia in there freebase state but as a salt have a fishy smell,. this fishy smell would be the smell that the sailors would be talking of I think. im going to make me one of those oxygen candles now :) I have never heard of them before but can think of some great uses for them. as always thanx for a great channel and another great video.
