    Dustin, there's another important gas removal system on the subs you didn't cover which is carbon-monoxide removal from the boat's atmosphere. Also, we always described the amine smell as a very strong fish smell.

    The preheater to the boiler stripper is nothing more than heat integration. Some waste heat from somewhere else on the ship is, I'm presuming, captured via a fluid and transferred there as a means to reduce the heating requirements of the boiler. Similar techniques are used in plants to offset utility costs. Here, probably done for safety reasons.
