    My understanding was we called them clinkers because they make a clink sound when you drop them in the canister, (my boat didn't have the nice side loading cans) so they would slide in and "clink" same with removing the burned one, you kinda had to bang them out, and that sucks when you're trying to be quiet.

    The measuring device(4:50) is called gas chromatograph. It has a capillary collum that separates a mixture of gas into its individual components. Then at the end of the collum, there are different types of sensors depending upon the type of gas and its concentration. These analytical instruments are like a miniaturized automatic laboratory. .Design, installation and commissioning of this kind of measuring instrument was a part of my former job.

    whenever i read Lithium (in this case LiOH) and water in one sentence i get shivers. So lets say, you have a hull breach and Oxygen gets low, you use the LiOH canisters, and if this stuff touches water, wont it immediatly burn all the oxygens and kill everyone? like it happened with Kursk? wasnt that the stuff that killed the remaining Sailors?

    Hey Destin, quick question. It looked as though the candles just pump out oxygen in the room they are burning in. At the start of the video you showed how every compartment has its own atmospheric monitoring. So if the bunk room is low on oxygen and the electrolysis machine is down, how do they disperse the oxygen from the candle to the rooms that need oxygen the most?

    the main takeaway of this video is that you have a 2-level redundancy for both creating O2 and scrubbing CO2, one active and one passive. That way if the active method, which is primary because it is essentially infinite as long as you have power, fails the passive backup can be used, but only for a limited time because it will be used up. Very cool.

    Would the preheating element in the MEA system be in place to reduce temperature differences and the damage that would be caused by repeated heating and cooling by ensuring a minimum temp before entry into the tank? Also, what would the contingency be for high tension alert situations when increased heart-rate and breathing would increase oxygen consumption? Burn more candles?

    You should do a deep dive on refineries. I work on a sulfur unit in a refinery and we use a lot of amine units. It's methyldiethanolamine though and we scrub hydrogen sulfide instead of co2. We do absorb some co2, but we move our nozzle up and down the tower to stop co2 absorption and maximize h2s absorption.

    Cant believe the electrolysis is used my 8th grade science fair , i thought people invented new ways for sub marines. 2 things. 1. If you creating pure o2 using electrolysis, we dont breath pure, it need to be mixed with other normal gasses including N2 to be breathable 2. If you do breath pure o2 it will burn your lungs. problem with this electrolysis is we always need pure water.

    A quick insight on the one part of the amine stripper you said you weren't clear on, and that's the preheating. In my university researcher days, we were designing an amine stripper for bio gas (from dairy cow waste) to make transportation fuel. There's a cool video idea in there somewhere for ya, and feel free to reach out if you're curious about it. The preheating of the amine is done using a heat exchanger as he said. What they're doing is rejecting heat from the hot newly lean amine into the cold rich amine, basically conserving the energy and lowering the heat load needed to boil it. Pretty simple really, he just didn't explain it super well. Typically this is done using a plate heat exchanger, and that appears to be what they're using there as well. So in your animation, between the pump and the tower that pipe would go to a heat exchanger with the pipe on the bottom.

    One would think there could be a way to remove the carbon from the CO2, because there's a whole O2 molecule being wasted pumping it out to sea, and carbon would be more compact to store and dispose of.

    With Amines in particular, there are 3 major types that are used, MEA I believe performs the best, but then there is always DEA, DGA and MDEA. In refineries, the latter is used more often (perhaps due to costs or something else). From my understanding, preheating helps increase the vapor pressure, which when it goes into the boiler, helps the regeneration process. If I am wrong, please do correct me.
