    Thank you for posting this video. It has been 14 years since I left my boat, and this really put me right back. This was the same class and size as my sub as well. I heard a shipmate say he had never seen a candle burned, and that was the case for me too. I was aboard for 2.5 -3 years and never seen one burned. I guess that's a good thing =D

    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.

    Cold liquid dissolves more gas than warm liquid thats why the amine gets heated. It is also why your pop goes flat faster when it's warm.
