Flooded Scrubber

Is wet scrubber material wasted scrubber material? If/when the loop/scrubber floods, can one dry the materiel out and re-use, or is it a total loss of absorbent?

Damp or staurated ? why take the chance. I would bin it and worry about fixing the leak to prevent wasting any more.

Once you've unpacked part used scrubber everybody says trash it. What was layered between used and unused is now mixed and the time to break through has become a statistical entity not a predictable one.

I also don't believe you could dry it in situ without a complicated system blowing a CO2 free dry gas through it for ages.

If it flooded and you got out OK congratulate yourself on your error recovery and damn yourself for letting it happen in the first place. Loosing a part used fill is the least of your worries.

Dump it!
For the sake of £8 would you take a chance with your life ?
I wouldn't but it is your call.

I can remember one of my tight Scots buds delaying everyone's dinner on the boat one nightwhile he had his left over sorb in the oven

....wonder if he's here somewhere (ye know who ye are Laddie!!). Right on cue took a CO2 hit the next day- made the Orkney papers and everything! Happily he's alright but I 'd think now he'd be the first to advise against it

This is when a little knowledge of chemistry becomes a dangerous thing. YES the reaction is reversible and yes theoretically you could re-use your sorb. But as with every reaction you need to take away one of the components to make the reaction complete or it will reverse as well.
So you need to refresh the air in the over to blow away the released carbon dioxide. AND the oven needs to be much hotter. This asks for an industrial oven. Is it done? Yes on an industrial scale CaO (Lime) is produced from Limestone (CaCO3) . don't try this at home, an kitchn oven is just not good enough.... You'll need just over 800 degrees Celsius or the Carbon Dioxide will react back into Limestone...
