 Below is an extract on storage from a  sodasorb pdf that answers my question. Talking about anaesthesia machines It says it should be changed if itis left in the machine for more than 48hrs. Dehydration seems their biggestconcern.     
Storage in Warehouse – Store Sodasorb absorbent in a clean, dry environment. Avoid contact with other

chemicals, acid, or water.

Sealed packages of Sodasorb absorbent are well protected against loss of moisture and have a shelf life oftwo years from the date of manufacture. An expiration date is marked on all packages. Once opened, packages arevulnerable to moisture loss, unless they are promptly and carefully resealed.

The moisture in Sodasorb, as well as other absorbents, will expand when frozen and result in some granulefragmentation and excessive dust. Packages which have been subjected to repeated freeze/thaw cycles should beexamined closely for dust and discarded if questionable.

Indicator Sodasorb should not be stored under intense light, especially ultra-violet light, since this maydegrade the ethyl violate indicator dye in Sodasorb absorbent.

Storage within the Anesthesia Machine – Carbon monoxide (CO) has been found to build up in unusedanesthesia units.

If Sodasorb absorbent is left in the machine, the absorber unit should be sealed and airtight. ChangeSodasorb absorbent which has been in an idle absorber unit for more than 48 hours.

Flush the anesthesia system with oxygen prior to use.

Avoid storage under intense lights. Indicator Sodasorb absorbent containing ethyl violet indicator is lightsensitive and may be subject to photodeactivation. It has been demonstrated that prolonged exposure of thegranules to high intensity lights will hasten the failure of the ethyl violet indicator in Sodasorb absorbent.

We recommend discarding any absorbent tinged with color. To avoid any under capacity for absorption,use only fresh Sodasorb absorbent for each charge.

It could be done easily just a twist on some studs counter to the fan rotation. Have an extra fan or 2 for backup quick connect electrical. Turn the absorbent canister into a cartridge and wrap for easy storage and deployment.

            Hi Pete,I can do, I will try to

remember tomorrow.  I like that idea to just replace the

canister onto a fan assembly.  In fact I love that idea, it

would have to be designed to replace quickly.

Hank, Pleases post some

pictures. My thought is multiple small scrubbers sealed in

cling wrap is the to go. When one is spent unwrap another

attach the fan and rock n roll. One could make a router

template to make the flat parts for a design like Alec's

and easily churn a couple of scrubbers.

             Brian,I

made a scrubber last

year that works a treat from 4 inch PVC pipe with a 2

inch

 hollow core made

with you guessed it 2 inch PVC end caps.

  I bought some screen to

cover the aluminum mesh and had to

 do a tiny bit of

machining.  I used a PVC threaded cap with

 foam under the cap to

compress the absorbent.  Not pretty,

 but works fantastic for

under 20 dollars.  Seems anything

 can be a scrubber!Hank

 Yes but you want

maximum

 surface area

to be coming in from the perimeter of the

 canister , the outside

should be all screen I should

 think.  I also have this coming by post soon

 Brian,I

 have looked at all sorts

of filters to see if there is

 anything mass produced & cheap that might

be

 easily adapted.

Haven't found anythingyet

 that is worthwhile adapting. There may be

something ( &

 I

continue tokeep my eyes open) but there are all

 sorts of peculiarities

specific to a submarines requirements

 like fan, spring, height

to diameter ratio & a

 transparent container& it seems easier, as

 Emile says, to start with

an acrylic

tube.Alan
