      I thought he was going to say the headphones button Is so cool because they pause the music and turn up the outside noise to hear people better, not just to pause music like my $40cdn Poms that are a knockoff of Airbuds that are a knockoff of airpods lol but good enough.

    23:37 The explanation is simple. The "amin" wants to be fizzy when it is cold but it wants to be flat when hot. So after the amin is saturated with CO2, it is heated up, which causes it to release that CO2. That is why the tower is called "boiling tower" because the CO2 is boiled out. This results in gaseous CO2 and the lean amin. The gaseous CO2 is pumped off by that compressor, the lean amin is cooled off and fed back to the absorption tower, where it completes the cycle.

    CO2 scrubbers and H2/hydrocarbon burners are the part most people never hear about. The other two significant factors are the carbon filters in the fan room to absorb all of the farts and the electrostatic scrubbers that keep the particulates out of the air. Is it pure air? Well, after 3-4 weeks out in a sealed tube, when you pop the hatch and ventilate the boat, you can literally smell every fish in the sea.

    It's been 30 years since I served on a submarine, and I can close my eyes and still smell amine and diesel fuel. Oh and wives HATED the smell. Most guys were made to strip outside before being allowed in the house, and then were made to scrub repeatedly in the shower before even being able to be in the same room with their wives. The smell never completely comes out of fabric.
