[PSUBS-MAILIST] CO2 Sorb

[via Personal_Submersibles]

As far as I know, the US and British Navies both still use LiOH, both active and passive (powered scrubbers and passive sheets for emergencies).

I think they use an amine solvent sytem to remove the CO2 and it's characteristic smell permeates  everything.

Don't tell the Navy. They use it by the ton.

Doesn't lithium hydroxide burst into flames when it comes into contact with water?
Thanks,

We'll be looking into Lithium Hydroxide for emergency use in P-VI as it is longer lasting per unit of volume, more efficient, and more temperature tolerant. It is also expensive by comparison. However, the sheer volume of material will be smaller, so easier to store.

Thanks Cliff. I was also running the numbers on Pisces VI. We will have the following for 1 pilot and 3 observers for a 8 hour mission time and 5 day emergency use
*400 cuft O2 outside hull emergency use (five 80cuft tanks)
*160-81 cuft O2 inside hull for up to 8hr mission use (two 80cuft bottles allowing for full discharge)
*144 lbs sodasorb emergency use (three 48lb jugs)
*12 lbs sodasorb for up to 8hr mission use (two scrubbers loaded)

Thank you,
